Credential Engine Technical Site

Technical Advisory Group

The Technical Advisory Group (TAG) promotes collaboration across, and harmonization of, standardization initiatives that are developing data models, vocabularies, and schemas for credentials and competency frameworks, and related competency information such as criticality ratings and assessment data typically captured with a wide variety of systems.

The goal is to identify, document and openly share solutions that support comparability of credentials and competencies across industries/sectors, human resource systems, education, and government systems.

The Application Work Group (AWG) is a standing subgroup of the TAG and supports members who are using Credential Engine data to design and/or develop applications. Credential Engine will provide technical team support, and online tools (e.g., GitHub repository, Slack Channel, Google Docs) and host meetings to bring members together to foster support. Anyone interested in sharing technical challenges and solutions is welcome to join the Applications Work Group.


Developers are able to leverage the the Credential Registry API to build applications that can read or publish as much or as little information about credentials as they need to.

The Credential Engine project's developers are using Dublin Core Application Profiles process to create systems that communicate all virtually all aspects of credentials.
