Ralf Handl updated ODATA-43:
----------------------------
Component/s: Vocabularies
> No indicator for optimistic concurrency control on EntityType or EntitySet level
> --------------------------------------------------------------------------------
>
> Key: ODATA-43
> URL: http://tools.oasis-open.org/issues/browse/ODATA-43
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: OData CSDL, Vocabularies
> Affects Versions: V4.0_WD01
> Environment: [Proposed]
> Reporter: Ralf Handl
> Fix For: V4.0_WD01
>
>
> Currently the only way for a server to indicate to its clients that entities of a given type use optimistic concurrency control, and that the client thus has to watch out for ETags in responses and provide appropriate If-Modified headers in requests is to use the ConcurrencyMode="Fixed" facet on simple properties of an entity type.
> If the server
> - does not wish to disclose which properties it uses for optimistic concurrency control, or
> - does not include the concurrency control properties in the entity type, or
> - includes the properties as part of a complex type
> it has no means to advertise the presence of optimistic concurrency control to the client.
