+OData or Open Data Protocol is a protocol build on HTTP which enables clients to access data in a uniform manner using URLs. As the name implies, the OData services exposes the data to clients, that is, it enables client to CRUD data models through http messages.
 
 The OData protocol supports data model descriptions and manipulation of the data. As description by the protocol specs, This is achieved through the following facilities: 
 
-* Metadata:      The description of the data model
-* Data:          The data sets
-* Querying:      This enables for filtering and other transformations on the data
-* Editing:       CRUD the data
-* Operations:    The represents some custom logic or functions on the data
-* Vocabularies:  Attaching custom semantics
