LRMI Metadata in use⤴

from @ Sharing and learning

There was no Dublin Core conference this year, but there was the DCMI Virtual Event over the second half of September, and for the last session of that I hosted a panel session on LRMI Metadata in use. The recordings for many of the sessions are now available, including our LRMI panel.

Further Details

We had four presentations, each fifteen minutes long, and a discussion at the end. Here’s an index for the recording and links to further resources mentioned. The four presentations were:

The discussion follows.

I have linked the title of each presentation to its starting point in the YouTube video.

About LRMI

You can find many of the LRMI properties in schema.org under the LearniningResource type, but you can also find LRMI Specifications on DCMI Website, including the version 1.1 of the specification as it was handed to DCMI, the terms in RDF (currently being updated), and concept schemes to provide controlled vocabularies for the values for some of those terms.

The DCMI LRMI Task Group curates LRMI and liases with other standards bodies that use the properties (notably schema.org). We meet the first Tuesday of every month. To join us, simply join the task group Mailing list.

If you’re interested in LRMI, join the google group for occasional updates about the spec, or to ask questions of the wider community.


I’ve not had any formal feedback from attendees, but I felt it went well and kind people are telling me similar (or not saying anything). A colleague on LRMI made a useful comment, that we should have had a few questions for audience at the start that would have helped us understand their background. That would help us gauge whether we had got the technical level of the content right.

I’m quite happy with the structure of the session, starting with design priniciples for LRMI as a whole, looking at how it has been applied to the description of learning resources, and finally how it has been applied to a search solution.  I hope there is enough of a logical flow there to give some coherence to what is a fairly long session. I was also happy with the discussion session afterwards, and the overall balance of how we used the time. Hopefully the recording and slides will be useful resources themselves, and in our latest LRMI call we agreed that it would be useful to repeat this type of presentation for other audiences (though I hope not as a manel). Many thanks to the presenters and others who took part.

Finally, I had a small role in organizing the event as a whole, enough to recognise how much effort Paul Walk and the other people on the organizing committee put in to making this a successful event–thank you.

LearningResource added to schema.org⤴

from @ Sharing and learning

A new type was added to the ‘pending’ terms in schema.org in the July release (release 9.0), LearningResource. It sits in the type hierarchy as a subtype of CreativeWork, and the definition and notes read:

The LearningResource type can be used to indicate CreativeWorks (whether physical or digital) that have a particular and explicit orientation towards learning, education, skill acquisition, and other educational purposes.

LearningResource is expected to be used as an addition to a primary type such as BookVideoProduct etc.

EducationEvent serves a similar purpose for event-like things (e.g. a Trip). A LearningResource may be created as a result of an EducationEvent, for example by recording one.

The properties in the domain of LearningResource are those that come from LRMI, nameley:  assesses, educationalAlignment, educationalLevel, educationalUse, and teaches. [Oops, learningResourceType is missing]

Although listed as pending, people using schema.org to describe educational resources are encouraged to use the term and report any issues. The only way terms can move from pending to the core of schema.org is if there is sufficient evidence of use.

The Whys and Why Nots

Before saying something about why LearningResource has been added, perhaps it’s worth saying why it wasn’t added before. After all LRMI is the Learning Resource Metadata Initiative, wouldn’t the first thing it did be say what is and isn’t a learning resource? Well, yes and no. In answering that question we acknowledged two facts. First, learning resources can be of any of the subtypes of Creative Work: Books, Videos, Articles, Atlases, Games and so on. Would  we add a “learning resource” subtype to each of these for Book-as-a-learning-resource, Video-as-a-learning-resource…? Secondly, what is and isn’t a learning resource often depends on use (a common definition for learning resource is “anything that can be used for learning”). So while a textbook is a learning resource by design, who would say you don’t learn something by reading Shakespeare? or reading a newspaper? or a recipe? I’ve seen custard used to help learning two distinct topics in physics (crystal nucleation when making ice cream, and thixotropic fluids)–does that make custard a learning resource? So the decision was made not to create learning resource as a separate type, but to add properties to all types of CreativeWork that allowed you to describe its educational characteristics and how it might be used for learning.

So why change now? It’s not because the argument above is wrong, especially not in pedagogic terms. However, such arguments have been seen to have a detrimental effect on efforts to curate learning resources. We are not teaching here, we are trying to help people find resources, and a different type of thinking is required. Creating a collection policy based on the definition of “anything can be a learning resource” has lead to unfocused, unsustainable collections, for example OER repositories that are 90% images, badly described because the description schema wasn’t set up for images, and swamping all other types of resources. Yes, images are useful for learning, but there are better ways to curate images than in a system designed fo learning resources. So the schema.org LearningResource type is for those resources that “that have a particular and explicit orientation towards learning, education, skill acquisition, and other educational purposes”. Although I wouldn’t want to put a hard boundary around this definition there are instances that clearly meet it–text books, instructional videos, assessments, lesson plans, online courses, infographics and so on. As an analogy: many things can be used as a hammer, or as a paperweight, you can even use hammers as paperweights and vice versa (with varying degress of success); that does not mean that there are things that are definitely hammers, or paperweights. Imagine what would happen if you set up a hammer store and all people could see in it were rocks (because, you know, who would say a rock can’t be used as a hammer?) Would that help anyone find your wonderfully specialized peen hammers, maul hammers, sledge hammers, soft-headed hammers, claw hammers and gavels?

We also found that, without a LearningResource type, we could not say that there is a schema for describing learning resources in the way that there is a schema for describing recipes.  This made it unneccesarily difficult for people wanting to describe educational charcteristics of resources to find the properties that would be useful. We hope this new type will improve the visibility and uptake of LRMI properties in schema.org

Finally, does this mean that a schema.org:Video cannot be a Learning Resource? After all LearningResource comes under CreativeWork not Video. Fortunately multiple typed entities are now well supported, so the best approach is to declare your instruction video as being both a Video and a LearningResource:

    "@context": "https://schema.org/",
    "@type": ["Video", "LearningResource"],
    "url": "https://www.youtube.com/watch?v=TIsUte5kfNw"
    "about": "Thixotropic liquids"

This has the added advantage that the use of LRMI properties is not limited to CreativeWorks, so if you have a Product that is designed “a particular and explicit orientation towards learning”, for example an educational toy, you can declare it as a schema:Product and a schema:LearningResource. As in noted in defintion about, some educational things are not really like CreativeWorks at all, for example lectures, museum visits, educational trips; for these the EducationEvent type serves a similar purpose to LearningResource.

Year 3⤴

from @ Sharing and learning

It is now three years since I left Heriot-Watt to become an independent consultant, and an anniversary is as good as time as any to look back and reflect. I cannot do so without thinking how this year has been a much harder for many of my friends and former colleagues than for me. Many of them had to strike because of issues relating to simple matters of equity and justice concerning pensions, pay gaps, and precarity; immediately after which they were hit with the massive systemic shock brought by covid-19. It annoyed me so much to hear reports of “dons on strike” (elitist bullshit that erases the work of my friends in learning technology, library, information services and other  professional services), and then to hear that “universities are closed” when I’ve seen my former colleagues  working miracles. Don’t get me started on having that work described as “so called blended learning” and conclusions being drawn from emergency provision extrapolated to online learning as a whole.

In comparison to all that my own work has been plain sailing. The second half of 2019 was fairly quiet. My work on K12-OCX, a metadata specification to help reusers of curriculum and content material, was paused while the project looked for more implementors; but I think it looks good. I was focusing on the Talent Marketplace Signaling W3C community, which made great progress in improving how schema.org to can be used to describe job postings. I was also involved in some work with Cetis LLP colleagues looking at Curriculum Analytics for Jisc. The idea is that, rather than use data to analyse learners, use it to analyse which aspects of a course or program work well, and look for clues as to why. I also kept up my voluntary work with Dublin Core groups, mainly the LRMI Task Group, where we added some new terms to schema.org, and with the Application Profile Interest Group, which let me explore some of the issues in using schema.org, for example in the K12-OCX spec.

Then around Christmas work started picking up. I got a contract from the USCCF to work supporting their T3 innovation network, mostly mapping data standards (exciting results on that soon) and keeping the Talent Signal community group ticking over. I also got new work from the Credential Engine, people I have loved working with since they were just a project on credential transparency. We are hoping to be able to work with Google to supply data from the Credential Registry that supports their Job Training (beta) Search. I have written before that I find some aspects of the work in the “Talent Marketplace” uncomfortable. Nothing encapsulates that more than seeing Melania Trump announce that the US Government  federal hiring process will value skills over degrees, and recognising how it links to the work I have been involved in linking job postings to skills and showing the competencies required to earn a credential. But, whoever takes the credit, it is work that has been building for five or more years; and whatever motives the people who announce it have, it benefits people who take non-traditional routes into jobs. I still think it is good work. My hope is that it shows the falsness of assuming Arts, Humanities and Social Sciences are inferior to STEM subjects in what they offer society, and that it helps people who aren’t able to follow the comparatively easy route of school to university to well-paid job.

Things are looking good for next year. There are some really interesting results coming. I am confident there will be interesting projects to work on, and I am looking forward to a couple of not-your-traditional-conferences I’m involved in. More on that soon.

#PressEdConf20 presentation: WordPress as technology for OER⤴

from @ Sharing and learning

The last couple of years I’ve been a keen follower of #PressEdConf, @pgogy and @nlafferty‘s Twitter-based conference on WordPress in Education. I haven’t been able to present in the previous two editions because they have taken place on a day that I have been travelling for an Easter visit to my parents. This year the the date changed, so I was able to present. I’ve been thinking about technologies for OER recently,  partly prompted by Risquez et al paper  Towards a Devolved Model of Management of OER? The Case of the Irish Higher Education Sector(see my thoughts here) and further stimulated by being asked to write a little about why open book publishing is important, so I thought I would take a look at WordPress as technology for OER through the lens of David Wiley’s ALMS framework.

The Tweets


I wish I knew a way to create a thread and schedule each tweet separately. I used tweetdeck’s scheduler, which reduced the stress of getting the tweets out (once I saw it working) but couldn’t thread those tweets.

Writing a presentation in 15 tweets is an interesting challenge. It’s not easy to distil what you want to say into ~15 statements and then to make each of those statement in 280 characters. Then you realise that people expect relevant gifs or engaging images of cats… whatever, I hope my holiday snaps were not too distracting.

With that in mind, thank you to all the other presenters.

It’s really rewarding to take part in this conference. Thanks to all those nice people that I interacted with during my presentation and others.

Huge thanks and respect to Pat at pgogy for running the conference. There have been a lot of comments about how the format was so opportune in this time of physical isolation, but I also know how Pat has faced extra stress and how he has responded like a hero.

Devolved Management of OER in Irish Higher Education?⤴

from @ Sharing and learning

I sometimes get asked for asked for advice by people who are thinking of setting up national infrastructure for OER based on institutional open access research repositories or similar, often with the rationale that doing such would mirror what has worked for open access research papers and cultural heritage. My advice is to think hard about whether it is appropriate to treat OER in the same way as these other types of resource. This week I read a paper, Towards a Devolved Model of Management of OER? The Case of the Irish Higher Education Sectorby  Angelica Risquez, Claire McAvinia, Yvonne Desmond, Catherine Bruen, Deirdre Ryan, and Ann Coughlan which provides important evidence and analysis on this topic.

The state of the nations

For some years Ireland had a National Digital Learning Resources (NDLR) service. As the Risquez et al report

“This centralised ecosystem provided a platform for creating OER, produced from funded digital projects available nationally and internationally, while harvesting and disseminating OER from other national repositories.[…] However, the centralised model also faced substantial financial and funding challenges: the network of coordinators was resource-intensive; the project remained reliant on recurrent strategic funding, which came under threat following the unprecedented global economic downturn; and it required significant recurring technical investment. Direct financial support for the NDLR was discontinued in 2012 in the middle of severe financial cutbacks across the HEI sector.

This mirrors almost exactly what happened in the UK with UKOER and Jorum. The paper sets out to examine

the potential for using existing institutional research repository infrastructure  for the purpose of ingesting, managing, and discovering OER produced by academics. This approach would imply a move from previous strategy around a centralised repository at the national level to a devolved model that relies on institutional research repositories.

It concludes

research repositories could potentially also serve as repositories of teaching materials, fostering parity of esteem between teaching and research. However, a range of important challenges were present, and alternative solutions emerged

Reading in to the paper, that ‘however’ is a big one, it’s like my “think hard” advice and here it is supported by thorough research and analysis.

The authors rightly start by emphasising what people like Catherine Cronin have said about the  need to have “policies in place at the institutional and national level to promote the curation and dissemination of OER beyond the individual responsibility of academics” My empahsis on national, because when the strains placed on the centralised national infrastucture in for OER in Ireland is contrasted with organic sustained growth of institutional repositories in the UK and elsewhere for OA research material,  I would argue that much of what is called organic sustained growth in OA research repositories is the result of open access mandates from funders. This is coupled with commitment from many researchers involved in open science (and other reseach areas, but there are some more complex arguments there that I can’t speak to). The personal commitment for OER is there. When I tweeted about this paper Viv Rolfe replied that her UKOER blogs are ten years old and she has supported their upkeep personally; I can easily think of a dozen or more similar cases– and ALT’s OER conference is driven by people who attend as self-funded delegates. Indeed the existance of the the OER conference depends on the community-based commitment of ALT. So I was really pleased that resourcing and recognition are rightly highlighted in the paper as important issues to address properly. OER are difficult, complex beasts, the people who produce them and care for them should be looked after. This also links to recognition of teaching in Higher Education. [Aside: I want to note that many of the people I think of in connection with this commitment are women, as are the authors of this paper, as were 60% of the respondents to the questionaire for this research. There’s a gender equity point here.] Back to the comparison with what makes OA repository infrastructure “sustainable”: there is plenty of commitment to Open Education from individuals, but barely any national policy. In my own context point to the important work of my friends Joe Wilson and Lorna M Campbell in keeping Open Scotland running. Absent national policy, the insitutional policy that we see tends to be driven by committed individuals and happens only when there is co-location of the right people in the right positions, as has happened at Edinburgh University and Glasgow Caledonian (pause to remember Marion Kelt).

OA research and OER are different

Commitment in the wrong cause, or policy for the wrong thing is not helpful. So we whould ask, is a respository infrastructure right for OERs? To investigate this Risquez et al were careful “to explore the voices often unheard, those of the teachers and professional service staff with whom we are engaging”, through focus groups, questionnaire including academics, learning technologists, librarians, repository managers. The evidence from this raises the crucial caveats and surfaces some important attitudes.

Questionaire results showed a majority thinking that Insititutional research repositories are not suitable for OER (by 26 to 10 responses, when those who felt they didn’t know enough to answer were removed):

The 10 reasons (from 5% of respondents) given to support the premise that institutional repositories were suitable for educational resources included ease of access, sharing and collaboration, and raising their own profile. For example, one of the respondents stated that: “It is a means to marketing and attracting growth, cross fertilisation and collaboration, thereby ensuring a broader perspective on educational relevance and application of material.

The 26 reasons (from 14% of respondents) given for the view that repositories were inappropriate for the sharing of educational resources included: other more flexible platforms available (7); lack of visibility and critical mass (7); the need for research and teaching outputs to remain separate (3); and other concerns such as lack of culture of sharing and the need for quality control.

To me, the results reported from a focus group of repository managers highlight differences between OER and OA research outputs. This group rightly identified curation of learning resources as new and challenging compared to collecting OA research papers, due to the OERs being complex, contextual, inhomogenous and editable. However I have less sympathy with some of the other comments, for example: “As data sets are being brought into repositories, so OER could be a type of ‘associated material’ to evidence the impact of research in teaching practice”–Nope. You won’t serve OER well by thinking of it as a side product of research, OERs are proper first-class resources to support what is the primary activity of most Universities and Colleges. Another example: “The only way I could ever see OER in my repository would be if they… have been through a rigorous peer review process and are the best of the best.” Also no, that’s not what OER are for. I mean it’s nice when you have “treasures” that you want to highlight, and it’s great if you want to share them, but for most it is better to think of sharing OER as sharing the effort in creating fantastic learning resources, not as the end point.

There were some interesting results on what would motivate sharing OER: altruistic motivations, recognition/credit/profile raising, collegiality and opportunities for collaboration and networking, and reciprocity; and equally interesting results on concerns in sharing via repository: “loss of control/ownership/intellectual property (42); repository functionality (20); time (17); lack of confidence in resources/fear of being ‘judged’ (15); lack of quality control (9), and lack of participation/reciprocity (5)”. For me the clincher is noted in the focus groups:

“those who were more experienced in OER use and production were also able to provide more historically contextualised views that were informed by their own and their colleagues’ practice. In some cases, they had taken a more flexible approach that had moved away from repositories towards the use of broader reaching social media tools, or their own professional networks: “Over time I’ve used repositories less and relied on my learning networks… with Creative Commons licenses”; “The concept of a repository is gone. It’s more about branding something within the open web environment e.g., a YouTube Channel”; and “I just put a skeleton of my course on [the Virtual Learning Environment] and share content through my WordPress blog.””

Valid concerns are reported about safeguarding the effort that has gone into producing resources, and assurance that copyright & licensing are handled properly, with interesting ideas about the repository not as a warehouse but as a point of curation. With respect to this I must note that similar concerns were raised when Cetis recommended the use of social sharing sites for disseminating OER, e.g. Flickr, YouTube, Vimeo, SlideShare etc. Whatever problems Flickr and others have had, they outlived Jorum. Looking back the only qualms I have about recommending those sites centre on the use of personal data in the business models that have kept some of them running.

Analysing the evidence from research repository managers and from those experiences in OER, the authors reach what I think it the correct conclusion:

“the culture of an institutional research repository is very different to that of a teaching and learning resource repository”

They say OER in a research repository runs the risk of being a square peg in a round hole, and conclude

“Overall, the rationale for supporting the accommodation of OER in institutional research repositories, which have a long-established history and a very different culture to that of learning resource repositories, was seriously questioned.”

So what’s the alternative?

I felt challenged by a comment from Catherine Cronin “(please!) let’s imagine infrastructure beyond repositories”, so here goes.

Let’s go back to that idea of the repository not as a warehouse but as a point of curation, and learn from those most experienced in OER as to how they with to care for and disseminate their resources. Let’s think of creating services that foster the collaborative creation of OER (H5P and PressBooks are among my favourites), and let’s create conduits to the open web. We tried to create such a conduit in the Core Materials project. Sure there was a centralised point of submission and search, and a copy was held locally, but the point wasn’t that resource ‘reposed’ there (there’s no rest for OERs). So we linkeded to where they were being sourced, and used APIs to post resources from the Core Materials hub to as many apropriate sites as possible (they can still be found on Flickr, YouTube and  SlideShare etc. ). Furthermore, we collected back the comments from users on those site to inform our searches. a similar approach can  be seen in OpenEd, where content is stored in format-appropriate institutional services (media hopper, library and archive collections etc.), but there is a central service providing promotion, assistance, curation, access, and dissemination through sites like TES learning resources and Wikimedia.

Let’s also think carefully about what we have learnt over the last ten years about how internet companies make their money, and try to avoid being one of next decades ed-tech debacles. Can we avoid selling ourselves (and our students) by working together through  platform coorperatives such as OpenETC? Open collaboratives building and using open source software to support open education seems like an idea, doesn’t it? Can we get committed people to push for national policies that support it?

Finally, there is an important note in the conclusions by Risquez et al, that:

“Ultimately, in the context of the enhancement of teaching and learning, any OER initiative should have an OEP component, which includes practices that support the reuse and production of OER through institutional policies, promote innovative pedagogical models, and respect and empower learners as co-producers on their lifelong learning paths (Ehlers, 2011).”

In fact, rather than trying to define Open Education in terms of the use of OER, let’s think of OER as resources for open education, and build the infrastructure for that.


This post started as a twitter thread, and much of the further thinking to build it into a blog post was prompted by the wonderfully supportive comments made on those tweets by @magsamond @catherinecronin @francesbell @clairemca @VivienRolfe @bmuramatsu and @joecar (apologies if I missed anyone)

Sharing and caring for Open Scotland⤴

from @ Sharing and learning

This month I will be curating for Open Scotland,  that is writing a blog post or two and tweeting a bit on the #OpenScot hashtag.  I’ve published the first blog post, Sharing curation in Open Scotland, and I am not going to reproduce the content here, so follow that link to read what I have to say about Dorothy Hodgkin, kindness in scientific research and how that relates to Open Scotland.

If you don’t know it,

Open Scotland is a voluntary cross sector initiative that aims to raise awareness of open education, encourage the sharing of open educational resources, and explore the potential of open policy and practice to benefit all sectors of Scottish education.

Open Scotland about page

The scope of Open Scotland includes

  • Open education practice
  • Open educational resources
  • Open policy
  • Open assessment practices
  • Open textbooks
  • Open source software
  • Open standards
  • Open online courses
  • MOOCs
  • Wikimedia projects

I have been (lightly) involved in Open Scotland one way or another since its inception with the Open Scotland Summit at the National Museum of Scotland in June 2013, subsequent creation of the Scottish Open Education Declaration. I’ve been increasingly aware that the effort for sustaining Open initiatives has fallen on too few people, and that’s as true of Open Scotland as it is for any other part of the open world, so when Lorna and Joe asked for volunteers to share the curation, I was happy to put my name down. If you feel similar please do likewise.

Resources and Objects: RDF and OOP talk about different things⤴

from @ Sharing and learning

Here’s a thing that I think has been at the root of some long discussions that I have been involved in where people involved in modelling data just don’t seem to agree on what goes in to a domain model, or on fine details of definitions. If it seems wrong or trivial to you, I’ld really appreciate any comments along the lines of ‘nope, you’ve misunderstood that …’ or ‘nope, everyone knows this and works around it, the disagreement must have been about something else’.

What I’m thinking causes these long discussions is that RDF and Object Oriented modeling methods (e.g. UML) talk about different things with the same terms. The resulting confusion is somewhat like a speaker of British English asking for something to be tabled in a meeting with folk from the US only to be mystified and offended when it is ignored

table transitive verb

1 a [US] to remove (something, such as a parliamentary motion) from consideration indefinitely
b British to place on the agenda

Merriam-Webster dictionary definition of table

RDF starts with resources, which are the things being described. Although identified with web identifiers (URIs, IRIs) they can be concrete objects, concepts, imaginary beings, in fact “anything that can be identified”. A relationship between a resource and something else can be asserted as being a property of the described resource. Resources of the same type can be grouped into classes so that a property can be associated with all instances of that type of resource. For example, in schema.org resources of type Person have a property name that is a string.In RDF terms I am a resource identified by <http://people.pjjk.net/phil#id> of type <http://schema.org/Person>. I am an instance of a <http://schema.org/Person>. Note that while I am identified by a URI you cannot retrieve me via that URI, instead you get sent a different resource with a different URI, that is a description of me.

Object Oriented methods start with objects, which are constructs that live only in information systems; the most important type of object in metadata contexts is a data object that is a description of something. Objects of the same type can be created through the definition of a class that defines the properties and methods of a type of object. While it is common practice to name object classes after the real-world thing that they represent, e.g. Person, when we create an object instance of such a class we do not create a person in the real world. The identifier for an object instance of type person is the identifier of the artifact in the computer.

So in RDF we have real things and write descriptions of them; in object oriented methods we have data things that we define. But we use terms like class, type, object, resource, instance when talking about both.

Context and shared understanding within communities is enough to avoid confusion between RDF and Object Oriented terms most of the time, but in JSON-LD they collide. In JSON-LD I can express the information about myself provided above as a description about me, or in terms of the W3C web architecture a representation of me.

{ "@context": {
        "sdo": "http://schema.org/"
    "@id": "http://pjjk.net/phil#id",
    "@type": "sdo:Person",
    "sdo:name": "Phil Barker",
    "sdo:url": "http://blogs.pjjk.net/phil/about/"

This translates to RDFXML as

<?xml version="1.0" encoding="UTF-8"?>
  <rdf:Description rdf:about="http://pjjk.net/phil#id">
    <rdf:type rdf:resource="http://schema.org/Person"/>
    <sdo:name>Phil Barker</sdo:name>

I could represent the UML class diagram for the JSON data object as something like: I could represent the UML class diagram for the JSON data object as something like:Note that @id and @type, which identify and provide a type for the JSON node, refer to objects in the real world for RDF.

Why does this matter? Well, it’s one thing to say that you like/don’t like me, it’s another to say that you like/don’t like a description of me. It’s one thing to make a copy of a description of me, another to make a copy of me.  We can make descriptions of things in RDF and make assertions about things in RDF, but if we say that a thing in our RDF model is a Description of Assertion, then we had better have a reason for wanting to be so meta as using RDF to make descriptions of Descriptions and assertions about Assertions. But when someone suggests that an RDF model should have PersonDescription in a oval in place of Person, maybe they really want a PersonDescription in box in a different type of entity relationship diagram.

Women in our time⤴

from @ Sharing and learning

A play list of programs about women from the BBC’s In Our Time radio programme.

I’m a big fan of In Our Time, the BBC radio programme where Melvyn Bragg discusses the history of ideas with academics. Some time back the BBC released the entire In Our Time back catalogue as episodes to download, via podcasts and the web. A while back I created a selection from the podcast feed for Roman History, presenting the episodes in more-or-less chronological order. Here’s a similar chronological selection of women who have been topics of In Our Time programmes. I’ve also edited together an rss file for a podcast feed if you would like this selection delivered direct to your listening device.

Discussions about individual women (natural or supernatural) are left-aligned; discussions of themes, movements or works by or concerning women are right aligned.


Lakshmi (लक्ष्मी) or Laxmi, is the Hindu goddess of wealth, fortune and prosperity. She is the wife and shakti (energy) of Vishnu, one of the principal deities of Hinduism and the Supreme Being in the Vaishnavism Tradition.

Marriage, also called matrimony or wedlock, is a socially or ritually recognised union between spouses that establishes rights and obligations between those spouses.

Antiquities (pre-5th century)

Hatshepsut (1507–1458 BC) was the fifth pharaoh of the Eighteenth Dynasty of Egypt and the second historically-confirmed female pharaoh.

Sappho (c. 630 – c. 570 BC) was an archaic Greek poet from the island of Lesbos. Sappho is known for her lyric poetry, written to be sung while accompanied by a lyre.

The Muses
In ancient Greek religion and mythology, the Muses are the inspirational goddesses of literature, science, and the arts. They are considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in these ancient cultures.

In creating this list I notice that:

The coverage of women in the series seems to have improved over time.

The geographic / cultural breakdown of the 36 individuals covered is rather Eurocentric:

  • African: 1 (Hatshepsut; who arguably predates Africa as a cultural identity)
  • Native American: 1 (Pocohontas)
  • Latin American: 1 (Frida Kahlo)
  • Asian: 3 (Lakshmi, Zenobia and Mary Magdalen; again, arguable about whether all these would have identified as Asian)
  • US: 2 (Emily Dickinson & Edith Warton) + 2 who moved there (Hannah Arendt & Emmy Noether).
  • European: 29
    • of whom: 15 were British

(This is my lame excuse for the Eurocentric headings by which I have divided the time line above.)

The field of endeavour of the Women covered breaks down as

  • Literature & Art 8
  • Social reform 10
  • Science 4
  • Religion & Philosophy  6
  • Rulers 8

(though if you want to object that someone being an author or a philosopher doesn’t preclude her from being a social reformer then I wouldn’t disagree)

Cycle route planning for Garmin eTrex Vista on Ubuntu 18.04⤴

from @ Sharing and learning

Obviously, this is a summer holidays post, not work related. One of my long-term popular posts on this blog is about Using Garmin eTrex Vista HCx with Ubuntu 14.04LTS & QLandkarte GT. That post has the info about how my eTrex is set up to connect to Ubuntu and to use OpenCycleMap, which still works for me. This post is just about the route planning, which has moved on. In short I use Google Maps in cycle mode plot the route, mapsToGPX.com to download a GPX of that route, gps babel to simplify and transfer the GPX file to the eTrex, and QMapShack to view and manage the various GPX files on Ubuntu. For navigation en route I follow a planned track on eTrex and/or on my phone using OSMAnd.

I tend to do my route planning for bike rides on Google Maps. I’ve tried lots of others, including the following a route using the Garmin eTrex or phone/OSMAnd as satnav, and routing on QMapShack, on Cycle Streets and Bing Maps; they all have their strengths, but Google wins because of two features. First, it’s dead easy to change the route by adding and dragging an intermediary way point; second street view and the aerial photos let me check out the type of road/track that it’s sending me on. There are still one or two stretches of cycle routes that it won’t add to routes, but another factor when compared to some other routing services is that it won’t send me on a detour over a rough path instead of a short distance on a medium busy road.

Once I have the route I want, I use mapsToGPX.com to convert it into a gpx files of the track point and route points that I download. For the route points I use the advanced options to get next turn info and turn directions. There may be other options, I haven’t looked because this does the job nice and simple (it’s nice to leave a donation if you think so too).

The only problem with the route points gpx file is that is has way too many  points for the Garmin. gpsbabel has a great option that will simplify by removing any points that are within a set distance of the line drawn between its neighbours. So if you’re happy with the line being up to 100m from the actual route point (which I find works fine) you can use

$ gpsbabel -i gpx -f track.gpx -x simplify,crosstrack,error=0.1k -o gpx -F track_s.gpx

That done I use QMapShack with the OpenCycleMap map to view and manipulate the route and track gpx files. I check that the route isn’t missing any obvious cycle routes. Google Maps is good enough at using cycle routes, but doesn’t display them particularly well, so they’re easy to miss. Actually editing the track or route on QMapShack is a bit of a pain, but it’s really quite quick to edit on Google Maps and re-download. I sometimes create waypoints in QMapShack with the name of the route point turn instructions. I put the route the track and the waypoints into a single project, (and if I am planning a multi-day tour I put all days into a single project) and save as a single GPX.

Three cycle rides in QMapShack as routes and tracks, one highlighted with waypoints.

I haven’t been able to get QMapShack to talk to eTrex, so I use gpsbabel to transfer the files:

$ gpsbabel [-t|r] -i gpx -f filename.gpx -o garmin -F usb:

Using -t at the front transfers track, -r transfers routes, using neither transfers the waypoints. See the docs for more options.

To transfer to my phone I just plug my phone into the USB and mount it for file transfer copy the file over and choose to display the GPX file from the Configure Maps option.

When riding, I just follow the track on the GPS device (phone or eTrex) with the waypoints giving me text hints (I would love to know if there is an easy way of setting proximity alarms for way points in bulk on the eTrex, to give alerts when a turn is coming). Having the route to display can be useful at times, but I have found that both devices tend to send me on unwanted detours and down unsuitable paths if I allow them to use the route for navigation. On the phone with OSMAnd, using a track for navigation works better, but there is a problem with the battery life on longer rides.

PressBooks and ePub as an OER format.⤴

from @ Sharing and learning

PressBooks does a reasonable job of importing ePub, so that ePub can be used as a portable format for open text books. But, of course, there are limits.

I have been really impressed with PressBooks, the extension to WordPress for authoring eBooks. Like WordPress it is available as a hosted service from PressBooks.com and to host yourself from PressBooks.org. I have been using the latter for a few months. It looks like a great way of authoring, hosting, using, and distributing open books. Reports like this from Steel Wagstaff about Publishing Open Textbooks at UW-Madison really show the possibilities for education that open up if you do that. There you can read what work Steel and others have been doing around PressBooks for authoring open textbooks, with interaction (using hypothe.is, and h5p), connections to their VLE (LTI), and responsible learning analytics (xAPI).

PressBooks also supports replication of content from one PressBook install to another, which is great, but what is even greater is support of import from other content creation systems. We’re not wanting monoculture here.

Open text books are, of course, a type of Open Educational Resource, and so when thinking about PressBooks as a platform for open text books you’re also thinking about PressBooks and OER. So what aspects of text-books-as-OER does PressBooks support? What aspects should it support?

OER: DERPable, 5Rs & ALMS

Frameworks for thinking about requirements for openness in educational resources go back to the very start of the OER movement. Back in the early 2000s, when JISC was thinking about repositories and Learning Objects as ways of sharing educational resources, Charles Duncan used to talk about the need for resources to be DERPable: Discoverable, Editable, Repurposable and Portable. At about the same time in the US, David Wiley was defining Open Content in terms of four, later five Rs and ALMS. The five Rs are well known: the permissions to Retain, Reuse, Revise, Remix and Redistribute. ALMS is a less memorable, more tortured acronym, relating to technical choices that affect openness in practice. The choices relate to: Access to editing tools, the Level of expertise required to use these tools, the content being Meaningfully editable, and being Self-sourced (i.e. there not being separate source and distribution files).

Portability of ePub and editing in PressBooks

I tend to approach these terms back to front: I am interested in portable formats for disseminating resources, and systems that allow these to be edited. For eBooks / open textbooks my format of choice for portability is currently ePub, which is essentially HTML and other assets (images, stylesheets, etc.) with metadata, in a zip archive. Being HTML-based, ePub is largely self-sourced, and can be edited with suitable tools (though there may be caveats around some of the other assets such as images and diagrams). Furthermore, WordPress in general and PressBooks specifically makes editing, repurposing and distributing easy without requiring knowledge of HTML. It’s a good platform for remixing, revising, reusing, retaining content. And the key to this whole ramble of a blog post is the ‘import from ePub‘ feature.

So how does  the combination of ePub and PressBooks work in practice. I can go to OpenStax, and download one of their text books as ePub. As far as I can see the best-known open textbook project doesn’t seem to make ePub available (Apple’s iPub is similar, but I don’t do iBooks so couldn’t download one). So I went to Siyavula and downloaded one of their CC:BY textbooks as an ePub. Chose that download for import into PressBooks and got a screen that lets me choose which parts of the ePub to import and what type of content to import it as.

List of sections of the ePub with tick box for whether to import in PressBooks, and radio button options for what type of book part to import as

After choosing which parts to import and hitting the import button at the bottom of the page, the content is there to edit and republish in PressBooks.

From here you can edit or add content (including by import from other sources), rearrange the content, and set options for publishing it. There is other work to be done. You will need to choose a decent theme to display your book with style. You will also need to make sure internal links work as your PressBooks permalink URL scheme might not match the URLs embedded in the content. How easy this is will vary depending on choices made when the book was created and your own knowledge of some of the WordPress tools that can be used to make bulk edits.

I am not really interested in distributing maths text books, so I won’t link to the end result of this specific example. I did once write a book in a book sprint with some colleagues, and that was published as an ePub. So here an imported & republished version of Into The Wild (PressBook edition).  I didn’t do much polishing of this: it uses a stock theme, and I haven’t fixed internal links, e.g. footnotes.


Of course there are limits to this approach. I do not expect that much (if any) of the really interesting interactive content would survive a trip through ePub. Also much of Steel’s work that I described up at the top is PressBook platform specific. So that’s where cloning from PressBooks to PressBooks becomes useful. But ePub remains a viable way of getting textbook content into the PressBooks platform.

Also, while WordPress in general, and hence PressBooks, is a great way of distributing content, I haven’t looked much at whether metadata from the ePub is imported. On first sight none of it is, so there is work to do here in order to make the imported books discoverable. That applies to the package level metadata in ePubs, which is a separate file from the content. However, what also really interests me is the possibility of embedding education-specific schema.org metadata into the HTML content in such a way that it becomes transportable (easy, I think) and editable on import (harder).
