Credential Transparency Description Language Fact Sheet

The Credential Transparency Description Language (CTDL) is a scheme (a type of-mini language that people and systems can use to understand each other even if their data comes from different sources) that anyone can use to share information about credentialing data. The CTDL not only provides a common and unified way of describing information in the Credential Registry, it is also an open language that can be used on the web. This powerful feature makes it dramatically easier for students, businesses, researchers, and automated systems to discover, understand, and compare information about credentials from a variety of sources.
