Remarks

The Open Data Protocol (OData) enables a binary data property of an entity exposed by a data service to be defined independently of an entry in a data feed by using a mechanism based on the following constructs:

  • Media resource - the binary large object data that is binary data, such as a video, audio, image or other media resources.

  • Media link entry - an AtomPub entry in a data feed that represents an entity and that has a reference to a related media resource.
