1.5 Prerequisites/Preconditions

The OData protocol does not provide a mechanism for a client to discover the existence and location of arbitrary data services (of the server). It is a prerequisite that the client obtain a URI to the server before the protocol can be used.

Neither the Atom Publishing Protocol (AtomPub) nor the OData protocol defines an authentication or authorization scheme. Implementers of the protocol ought to review the recommended security prerequisites in Security Considerations for Implementers (section 5.1) of this document and in [RFC5023] section 15.
