ATOM serialization on server side
Hi,
Is there is JIRA for building the ATOM based serializer for server side? I looked in the JIRA system and could not find it. Also is there anybody working on that solution for V4?
Thanks
Ramesh..

For what it's worth, we deprioritized ATOM in .NET for the same reason.

Hi Ramesh,
no there is neither a JIRA item nor is anyone working on this right now.
With V2 we implemented atom/xml first and everybody was screaming for JSON so this time we thought to go with JSON first :-)
One could always use the client atom serializer/deserializer even on server side. But that would mean no payload validation as we do with the server JSON serializer/deserializer.
Best Regards,
Christian

Christian,
Makes absolute sense. MAY, MUST and SHOULD from the spec should be treated differently in client and server sides.
I will add a JIRA, and will see if I can contribute for it.
Thanks.
Ramesh..

Hi Ramesh,
In my point of view a client should be as lenient as possible when it comes to accepting a payload and constructing them. This assures you a client which can consume many OData Services even if they do not completely adhere to the OData Specification in some points. Also you might not want to query the metadata on client side and thus have to construct the payload as best you can.
A server on the other hand should make sure that every data he receives does at least not contain malicious data. And he should never give back a payload which does not adhere to the OData Specification. This is possible because you always have the metadata on server side. So in my opinion we should do validations there.
This is we introduced separate serializers/deserializers for client and server.
WDYT about this approach?
Best Regards,
Christian

I always wondered why client serializer/deserializer was not used for JSON too, can you explain what the extra validation on server side?
