Global micro-credential mapping project report⤴

from @ Sharing and learning

A project I worked on with Credential Engine has just had its (first?) report published: Global Micro-Credential Schema Mapping: A Vital Step Towards Interoperability and Mobility.

This project was suggested by the Credential Engine‘s CTDL Advisory Group, and ran from January to June this year. That was slightly longer than its initial 3 month estimate, but we covered more than we initially expected. The intended benefits were outlined by the CTDL Advisory group, and centre on making sure that micro-credentials issued in one jurisdiction are understandable in others, even when different data specifications have to be used in order to comply with local technical and political requirements and practices where they are issued. The end result envisaged is that individuals can have their achievements recognized globally.

We used the Data Ecosystem Mapping Tool to map elements from various specifications and standards related micro-credentials, such as CTDL, Open Badges, the versions of Open Badges used by a commercial badge issuer in Canada and Australia, W3C Verifiable Credentials and the European Learning Model: more information on those and specs and who I mean by “we” are in the report.

The results are available on the Credential Engines DESM site where you can see the degree of semantic alignment between these schemas, and there are some reflections on the results in the report.

New resources explaining the Data Ecosystem Schema Mapping tool⤴

from @ Sharing and learning

The Data Ecosystem Schema Mapping (DESM) tool is one of the projects that I am working on for the US Chamber of Commerce Foundation’s T3 Innovation Network.  DESM is a specialized tool for creating, editing, maintaining and viewing crosswalks between data models, these crosswalks are based on the degree of semantic alignment between terms in the different schemas. Colleagues on the project have produced two one-page fliers about DESM that have just been published: one explaining what DESM is and how it works, the other providing guidance on mapping projects that use DESM.

Watch this space for more about our use of DESM in both T3 and Credential Engine projects.

What am I doing here? 2. Open Competencies Network⤴

from @ Sharing and learning

I am continuing my January review of the projects that I am working on with this post about my work on the Open Competencies Network (OCN). OCN is a part of the T3 Network of Networks, which is an initiative of US Chamber of Commerce Foundation aiming to explore “emerging technologies and standards in the talent marketplace to create more equitable and effective learning and career pathways.” Not surprisingly the Open Competencies Network (OCN) focuses on Competencies, but we understand that term broadly, including any “assertions of academic, professional, occupational, vocational and life goals, outcomes … for example knowledge, skills and abilities, capabilities, habits of mind, or habits of practice” (see the OCN competency explainer for more). I see competencies understood in this way as the link between my interests in learning, education, credentials and the world of employment and other activities. This builds on previous projects around Talent Marketplace Signalling, which I also did for the US Chamber of Commerce Foundation.

About the work

The OCN has two working groups: Advancing Open Competencies (AOC), which deals with outreach, community building, policy and governance issues, and the Technical Advisory Workgroup. My focus is on the latter. We have a couple of major technical projects, the Competency Explorer and the Data Ecosystem Standards Mapping (DESM) Tool, both of which probably deserve their own post at some time, but in brief:

Competency Explorer aims to make competency frameworks readily available to humans and machines by developing a membership trust network of open registries each holding one or more competency frameworks and enabling search and retrieval of those frameworks and their competencies from any registry node in the network.

DESM was developed to support data standards organizations—and the platforms and products that use those standards—in mapping, aligning and harmonizing data standards to promote data interoperability for the talent marketplace (and beyond). The DESM allows for data to move from a system or product using one data standards to another system or product that uses a different data standard.

Both of these projects deal with heterogeneous metadata, working around the theme of interoperability between metadata standards.

About my role

My friend and former colleague Shiela once described our work as “going to meetings and typing things”, which pretty much sums up the OCN work. The purpose is to contribute to the development of the projects, both of which were initiated by Stuart Sutton, whose shoes I am trying to fill in OCN.

For the Competency Explorer I have helped turn community gathered use cases into  features that can implemented to enhance the Explorer, and am currently one of the leads of an agile feature-driven development project with software developers at Learning Tapestry to implement as many of these features as possible and figure out what it would take to implement the others. I’m also working with data providers and Learning Tapestry to develop technical support around providing data for the Competency Explorer.

For DESM I helped develop the internal data schema used to represent the mapping between data standards, and am currently helping to support people who are using the tool to map a variety of standards in a pilot, or closed beta-testing. This has been a fascinating exercise in seeing a project through from a data model on paper, through working with programmers implementing it, to working with people as they try to use the tool developed from it.
