Subject: [OASIS Issue Tracker] Created: (ODATA-531) Simplify OptimisticConcurrency in Core vocabulary
Simplify OptimisticConcurrency in Core vocabulary ------------------------------------------------- Key: ODATA-531 URL: http://tools.oasis-open.org/issues/browse/ODATA-531 Project: OASIS Open Data Protocol (OData) TC Issue Type: Bug Components: Vocabularies Affects Versions: V4.0_CS01 Environment: [Proposal] Reporter: Michael Pizzo Fix For: V4.0_CSD03 The OptimisticConcurrencyControl term in the Core vocabulary currently defines a complex type that contains a single collection-valued property: <Term Name="OptimisticConcurrencyControl" Type="Core.OptimisticConcurrencyControlType" AppliesTo="EntitySet"> <Annotation Term="Core.Description" String="If present, the annotated entity set uses optimistic concurrency control" /> </Term> <ComplexType Name="OptimisticConcurrencyControlType"> <Property Name="ETagDependsOn" Type="Collection(Edm.PropertyPath)" Nullable="true"> <Annotation Term="Core.Description" String="The ETag is computed from these properties" /> </Property> </ComplexType> This intermediate complex type means that applying the vocabulary requires an extra <Record> and <PropertyValue> wrapper: <EntitySet Name="Entities" Type="Self.Entity"> <Annotation Term="Core.OptimisticConcurrencyControl"> <Record> <PropertyValue Name="ETagDependsOn"> <Collection> <PropertyPath>LastModified</PropertyPath> </Collection> </PropertyValue> </Record> </Annotation> </EntitySet> This is unnecessarily cumbersome. We can remove the extra complex type and just create a term whose type is Collection(Edm.NavigationPropertyPath), as in: <Term Name="OptimisticConcurrencyControlProperties" Type="Collection(Edm.PropertyPath)" AppliesTo="EntitySet"> <Annotation Term="Core.Description" String="The set of properties that are used to compute the ETag" /> </Term> Which would be applied much more simply as: -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
