Much of the data on the Web today lives in silos, needing different protocols, APIs, and formats to query and update the data. With the rapid growth of online information, open data protocols and services are in demand more than ever before. OData is a REST-based Web protocol. It builds on HTTP, AtomPub, and JSON using URIs to address and access data feed resources. It enables information to be accessed from a variety of sources including (but not limited to) relational databases, file systems, content management systems, and traditional Web sites. OData 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.
