Description

"Yadis.org is emblematic of what identity commons was founded to promote: interoperability of multiple right answers.

Yadis is an open source, open protocol project started by the creators of OpenID and LID who decided to make their different approaches to authentication work together and invite anyone else who wanted to to join them."
