Metadata as an OData service

XMLWordPrintable

      Instead of a monolithic XML metadata document the metadata could be made available as an OData service with a fixed schema:

      Entity types

      • EntitySet
      • EntityType
      • Property
      • Annotation
      • ...

      Entity sets

      • EntitySets
      • EntityTypes
      • Properties
      • Annotations
      • ...

      This meta-service could be accessed via a canonical URL, ideally ~/$metadata/ with $format=atom/json or a corresponding Accept header.

      This would allow accessing only parts of the metadata document the client is interested in and simplify parsing for clients: they only need to know how to interpret "normal" OData feed and entity response payloads without needing a separate metadata format.

      It would also conveniently provide a JSON format for metadata.
