Abstract

Credentials are a part of our daily lives; driver's licenses are used to assert that we are capable of operating a motor vehicle, university degrees can be used to assert our level of education, and government-issued passports enable us to travel between countries. This specification provides a mechanism to express these sorts of credentials on the Web in a way that is cryptographically secure, privacy respecting, and machine-verifiable.

Checking into the status of JSON-LD 1.1 ...

iherman commented 5 years ago

The JSON-LD Working Group has just closed all its outstanding technical issues see:

and considers the technical work, in terms of features of the language, as closed.

The group is planning to work only on editorial and CR related issues (test cases, reports, etc.) at the upcoming TPAC F2F and intends to issue a request for CR a few of weeks after TPAC.

I think we can safely say that the future Recommendation is ready as far as the VC work is concerned.
