> -------------------------------------------------------------
>
> Key: ODATA-1096
> URL: https://issues.oasis-open.org/browse/ODATA-1096
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: Protocol
> Affects Versions: V4.01_CSD02
> Reporter: Ralf Handl
> Fix For: V4.01_CS01

>
> The second paragraph of section 9.1.4 is a quote from RFC7231 and somewhat hard to parse. Replace it with text that expresses its intention: send an ETag only if the client can reasonably "know" the current entity representation that has not been sent in the response:
> (1) For a PUT request: if the response body of a corresponding 200 response would have been identical to the request body, i.e. no server-side modification of values sent in the request body, no "calculated" values.
> (2) We could extend this to PATCH requests and if a corresponding 200 response would have consisted of
> - values sent in PATCH request body, plus
> - server-side values corresponding to ETag sent in If-Match header of PATCH request (for values not sent in PATCH request body)
