Delta response encoding is unnecessarily verbose and change type is missing when odata.metadata=none

Close without action. Accepted: https://www.oasis-open.org/committees/download.php/50924/odata-meeting-55_on-20131003-minutes.html#odata-539 Original proposal part (a) is covered by ODATA-538 Original proposal part (b) is covered by ODATA-527 Original proposal was: (a) Define a separate annotation for change type in delta responses, so that change type can be determined even when the Context URL is omitted. The rationale being that Context URL is a hybrid of information that is otherwise known to a metadata-aware client (which can remember what it asked for in the GET request). Apart from odata.type (which is covered in ODATA-538 ), the change type would appear to be the only information about delta responses that a metadata-aware client cannot determine from metadata it already holds, and the request it knows it sent. Having this information embedded within a Context URL, which the client does not need the rest of, is questionable. (b) Require servers to use relative URLs in id/source/target, or at least allow clients to "indicate that they Prefer" relative URLs.
