The XDI Context Provider implements IdAS operations by sending XDI messages to an XDI endpoint (or by applying them to a local XDI document).

It maps IdAS operations to XDI operations. This mapping is described in further detail at IdAS XDI Mapping.

Implementation

The XDI Context Provider is a Higgins Context Provider, i.e. it implements the IContextFactory, IContext and other interfaces of the IdAS API.
