User Story

MIT xPro students often take courses/programs as part of their ongoing professional development. Although students get certificates (web page hosted in xPro platform, similar to OpenEdX) upon completion, relying parties often want a higher level of assurance. MIT xPro wants to offer Verifiable Credentials so that students can take their credentials with them and so that relying parties have a trusted process for verification that doesn't require them to contact Open Learning.

Data Concepts

There will be 2 types of credentials issued:

• Completion of a course
• Completion of a program

We currently are not permanently hosting credential definitions (e.g. a Credential Engine Registry) but will be open to it in the future. At the moment, we prefer to define key aspects of the credential itself. The concepts/metadata is limited enough that we've been able to use basic schema.org definitions without much confusion. We used the "reverse" LD definition awardedOnCompletionOf to deal with the navigability issue.

• DCC LD Context with awardedOnCompletionOf
• xPro github issue: https://github.com/mitodl/mitxpro/issues/1969
• See additional examples at the end
