Describe your idea: Include linked data support in all your projects – either exposing RDF directly (perhaps as RDFa) or via a SPARQL endpoint.
See http://esw.w3.org/topic/SweoIG/TaskForces/CommunityProjects/LinkingOpenData/

What problem does it solve?: Exposes data directly to the Web, allowing easier reuse and mashups. More interoperable than proprietary APIs.
