[ https://issues.oasis-open.org/browse/ODATA-980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=63915#comment-63915 ] Michael Pizzo commented on ODATA-980: ------------------------------------- Martin: specifying metadata as part of the query option (like in the path) allows caching, where in the header it does not. > SchemaVersion header, $SchemaVersion query option, or root URL versioning > ------------------------------------------------------------------------- > > Key: ODATA-980 > URL: https://issues.oasis-open.org/browse/ODATA-980 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData Protocol > Affects Versions: V4.01_WD01 > Environment: Proposed > Reporter: Ralf Handl > Fix For: V4.01_WD01 > > > The SchemaVersion header and accompanying annotation are intended to allow breaking changes without having to change the service root URL. > How does this combine with type referencing in the @odata.type annotation? > We could annotate the @odata.type annotation with the @Core.SchemaVersion: > "@odata.type":"https://some.whe.re/$metadata" > "@odata.type@Core.SchemaVersion":"2.0.1", > Or we could add a system query option and make the schema version part of the URL: > "@odata.type":"https://some.whe.re/$metadata?$SchemaVersion=2.0.1", > Or we could reconsider this and fall back to root URL versioning: > "@odata.type":"https://some.whe.re;v=2.0.1/$metadata", -- This message was sent by Atlassian JIRA (v6.2.2#6258)
