"OSIS brings together many identity-related open-source projects, and synchronizes and harmonizes the construction of an interoperable identity layer for the internet from open-source parts. Its first deliverable is interoperability with Microsoft CardSpace, although OSIS also encompasses alternate technologies such as OpenID and SAML."
