This morning at PDC and on the ADO.NET Data Services team blog, we announced the Open Data Protocol (OData). OData which was previously known informally as the "data services protocol", is an open protocol for sharing data that provides a way to break down data silos and increase the shared value of data by creating an ecosystem in which data consumers can interoperate with data producers in a way that is far more powerful than currently possible, enabling more applications to make sense of a broader set of data. Every producer and consumer of data that participates in this ecosystem increases its overall value. This is similar in many ways to Microsoft’s efforts with ODBC, although applied to the Web environment and supporting a variety of data sources including (but not limited to) relational databases, file systems, content management systems, and traditional web sites.
