This SIG is dedicated to maintaining information about available credential formats for the benefit of OWF projects and the wider community. The topic is more complex than one might assume on first sight, since there are more than 14 formats for representing digital credentials and most of those formats can be combined with different signature algorithms, ways to represent cryptographic keys (with alone more than a hundred DID methods), status management methods, trust management methods and so on.
There is pre-existing work started at Internet Identity Workshop (IIW 34, Spring 2022) and extended and augmented during Rebooting the Web of Trust (RWOT-XI, The Hague, Sept 2022).

The pre defined Google sheet was split into the data part and the visualization part. The data part is now in the data folder and the visualization part is in the viewer folder. This allows to use the power of github to collaborate on the data and to reuse the data in other projects.
- Data: Includes the data for the viewer.
- viewer: Includes the viewer that will visualize the data.
