Progress report for Educational and Occupational Credentials in schema.org

[This is cross-posted from the Educational and Occupational Credentials in schema.org W3C community group, if you interested please direct your comments there.]

Over the past few months we have been working systematically through the 30-or-so outline use cases for describing Educational and Occupational Credentials in schema.org, suggesting how they can be met with existing schema.org terms, or failing that working on proposals for new terms to add. Here I want to summarize the progress against these use cases, inviting review of our solutions and closure of any outstanding issues.

Use cases enabled

The list below summarizes information from the community group wiki for those use cases that we have addressed, with links to the outline use case description, the wiki page showing how we met the requirements arising from that use case, and proposed new terms on a test instance of schema.org (may be slow to load). I tried to be inclusive / exhaustive in what I have called out as an issue.

1.1 Identify subtypes of credential

1.2 Name search for credential

1.3 Identify the educational level of a credential

1.4 Desired/required competencies

1.6 Name search for credentialing organization

1.8 Labor market value

1.11 Recognize current competencies

1.13 Language of Credential

2.1 Coverage

2.2 Quality assurance

2.5 Renewal/maintenance requirements

2.6 Cost

3.1 Find related courses, assessments or learning materials

3.3 Relate credentials to competencies

3.4 Find credentialing organization

4.2 Compare credentials

  • Credentials can be compared in terms of any of the factors above, notably cost, compentencies required, recognition and validity.

4.3 Build directories

1.5 Industry and occupation analysis

1.7 Career and education goal

1.10 Job vacancy

3.2 Job seeking

Use cases that have been ‘parked’

The following use cases have not been addressed; either they were identified as low priority or there was insufficient consensus as to how to enable them:

1.9 Assessment (see issue 5, no way to represent assessments in schema.org)

1.12 Transfer value: recognizing current credentials (a complex issue, relating to “stackable” credentials, recognition, and learning pathways)

2.3 Onward transfer value (as previous)

2.4 Eligibility requirements (discussed, but no consensus)

3.5 Find a service to verify a credential (not discussed, low priority)

4.1 Awarding a Credential to a Person  (not discussed, solution may be related to personal self-promotion)

4.4 Personal Self-promotion (pending discussion)

4.5 Replace and retire credentials (not discussed, low priority)

Summary of issues

As well as the unaddressed use cases above, there are some caveats about the way other use cases have been addressed. I have tried to be inclusive / exhaustive in what I have called out as an issue,–I hope many of them can be acknowledged and left for future contributions to schema.org, we just need to clarify that they have been.

  • Issue 1: whether EducationalOccupationalCredential is a subtype of CreativeWork or Intangible.
  • Issue 2: competenceRequired only addresses the simplest case of individual required competencies.
  • Issue 3: whether accreditation is a form of recognition.
  • Issue 4: the actual renewal / maintenance requirements aren’t specified.
  • Issue 5: there is no way represent Assessments in schema.org
  • Issue 6: there is no explicit guidance on how to show required learning materials for a Course in schema.org.

There is an issues page on the wiki for tracking progress in disposing of these issues.

Summary of proposed changes to schema.org

Many of the use cases were addressed using terms that already exist in schema.org. The changes we currently propose are

Addition of a new type EducationalOccupationalCredential

Addition of four properties with domain EducationalOccupationalCredential:

Addition of EducationalOccupationalCredential to the domain of two existing properties (with changes to their definition to reflect this):

Addition of EducationalOccupationalCredential to the range of three existing properties:

Educational and occupational credentials in schema.org

Since the summer I have been working with the Credential Engine, which is based at Southern Illinois University, Carbondale, on a project to facilitate the description of educational and occupational credentials in schema.org. We have just reached the milestone of setting up a W3C Community Group to carry out that work.  If you would like to contribute to the work of the group (or even just lurk and follow what we do) please join it.
