Welcome to the OASIS XDI TC Technical Committee Wiki. XDI is a format and protocol for semantic data interchange -- a way different systems, applications, and databases can describe, map, exchange, link, synchronize, and protect data using a shared semantic graph model. XDI uses a globally addressable contextual graph model based on the RDF graph model defined by the W3C Semantic Web activity.

The XDI TC is currently in the process of drafting the XDI 1.0 suite of specifications. This wiki is a tool to help use share information, develop proposals, and document examples. We try our best to keep it current and navigation-friendly for newcomers to XDI, however since it is a working wiki, you will almost certainly find pages or examples that are not fully current with draft specifications.

Pages recently added or significantly updated: LinkContractBranches, SemanticFiltering, GroupMessaging, CoreSpecRevisions, JsonXdiMapping.
