During MIX11 this week, Pablo Castro, Software Architect in the Data and Modeling Group at Microsoft, gave a talk named “OData Roadmap: Services Powering Next Generation Experiences“.

Pablo gave demos of what’s cooking for OData and what to expect over the coming months.

One thing that he demonstrated was extensibility with Shared Vocabularies. This allows tools and applications to offer a richer experience through annotations on OData feeds.

Pablo used Sesame Data Browser as an example of how Shared Vocabularies can be used. With annotations on the MIX11 Speakers and Sessions feeds, Sesame is able to display visit cards (VCards) for speakers and a calendar view containing sessions.

I invite you to watch the video recording on the session’s page. The demo starts at 0:52:34.

Vocabularies for OData were introduced on the OData blog. The current stage is exploratory and implementation is open for discussion in the OData mailing list.
Note: this feature is not available in the currently public version of Sesame Data Browser (1.0.7).
