Subject: [OASIS Issue Tracker] (ODATA-1416) Dynamic capabilities for containment cases
Ralf Handl created ODATA-1416: --------------------------------- Summary: Dynamic capabilities for containment cases Key: ODATA-1416 URL: https://issues.oasis-open.org/browse/ODATA-1416 Project: OASIS Open Data Protocol (OData) TC Issue Type: Improvement Components: CSDL JSON , CSDL XML, Vocabularies Affects Versions: V4.01_OS Reporter: Ralf Handl Capabilities are annotated on entity sets, and for "nested" / contained entities they are expressed via Capabilities.NavigationRestrictions. This works fine for static capabilities (can't ever update, can't ever delete), but does not allow expressing dynamic capabilities via boolean properties on the nested entities. Example: * {{Orders}} have (contained) {{items}} * Each {{Item}} has a property {{isUpdatable}} The corresponding navigation restriction is (rather bulky): {code:xml} <Annotations Target="MyService.EntityContainer/Orders"> <Annotation Term="Capabilities.NavigationRestrictions"> <Record Type="Capabilities.NavigationRestrictionsType"> <PropertyValue Property="RestrictedProperties"> <Collection> <Record Type="Capabilities.NavigationPropertyRestriction"> <PropertyValue Property="NavigationProperty" NavigationPropertyPath="items"/> <PropertyValue Property="UpdateRestrictions"> <Record Type="Capabilities.UpdateRestrictionsType"> <PropertyValue Property="Updatable" Path="isUpdatable"/> </Record> </PropertyValue> </Record> </Collection> </PropertyValue> </Record> </Annotation> </Annotations> {code} Unfortunately the above annotation is wrong, because bq. For annotations embedded within or targeting an entity set or a singleton, the path is evaluated starting at the entity set or singleton, i.e. an empty path resolves to the entity set or singleton, and non-empty paths MUST follow the rules for annotations targeting the declared entity type of the entity set or singleton. -- This message was sent by Atlassian Jira (v8.3.3#803004)
