[ http://tools.oasis-open.org/issues/browse/ODATA-126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32830#action_32830 ] Ralf Handl commented on ODATA-126: ---------------------------------- The current model (picture and edmx) are checked into SVN: - https://tools.oasis-open.org/version-control/browse/wsvn/odata/trunk/spec/examples/MetadataService/MetaModel.edmx?sc=1 (V3 format :-) - https://tools.oasis-open.org/version-control/browse/wsvn/odata/trunk/spec/examples/MetadataService/EntityDesignerDiagram.png?op=dl&rev=0&isdir=0 ToDo: - Convert Edmx to V4 format (could someone write an XSL translation for that?) - Transform entity types AnnotationsElement and ParameterType into complex types and targeting navigation properties into complex properties - Add Documentation complex property type to all approprioate entity types Feedback is highly welcome! > Metadata as an OData service > ---------------------------- > > Key: ODATA-126 > URL: http://tools.oasis-open.org/issues/browse/ODATA-126 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: New Feature > Components: OData CSDL, OData Protocol , OData URL Conventions > Affects Versions: V4.0_WD01 > Reporter: Ralf Handl > Assignee: Ralf Handl > Fix For: V4.0_WD01 > > > 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 > - ValueAnnotation > - ... > Entity sets > - EntitySets > - EntityTypes > - Properties > - VallueAnnotations > - ... > 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. > Accepted: https://www.oasis-open.org/committees/download.php/48097/odata-meeting-23_on-20130130_31-F2F-minutes.html#odata-126 -- 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
