    [ http://tools.oasis-open.org/issues/browse/ODATA-126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33119#action_33119 ] 

Stefan Drees commented on ODATA-126:

Is there a mapping to base a transform for the MetaModel.edmx transition from v3 to v4 upon?
I'ld be willing to act on the first item in the above todo lit (inside Ralf's comment.

> 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
>         Environment: [Proposed]
>            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
