22.214.171.124.8 Update Request Containing a Customizable Feed Property Mapping
Applies to the OData 2.0 and OData 3.0 protocols
In OData 2.0 and OData 3.0, it is possible to map the value of a property on an EntityType to another location in the feed. If the EntityType instance contained in an UpdateEntity, UpdateComplexType, or UpdatePrimitiveType Request has a property mapping defined on it and the Content-Type is AtomPub, then the request body MUST be formatted by using the EntityType formatting rules defined in Entity Type (as an Atom Entry Element) with a Customizable Feed Property Mapping (section 126.96.36.199.2.1).
When sending an Update Request to an EntityType instance that has a customizable feed property mapping, the client MAY include the property value in an m:properties element as described in Entity Type (as an Atom Entry Element) (section 188.8.131.52.2). If the property value is included in the m:properties element (as described in section 184.108.40.206.2), the data service MUST use that value when updating the EntityType instance.
