UWS 1.1

[Mark Taylor]

Hi grid,

I'm interested in implementing a UWS-1.1-aware client in order to
improve the way that I do blocking to wait for an asynchronous
TAP response (sec 2.2.1.1).

Are there some deployed TAP services out there that implement
UWS-1.1 blocking behaviour?  Preferably using the UWS 1.1 namespace?
I'd like to test client behaviour against them.

Thanks

Mark

I believe that there are now several implementations that are being updated to adhere to the new version. It has been brought to my attention that the UWS 1.1 schema was not available in the text of the last WD that was published to the IVOA document store. For those that need a copy, it is available in volute

It concerns how other standards might signal which version of UWS that they are using. My current feeling is to remove this text entirely and leave it up to the other standard documents to signal the mechanism that they want to use. I think that part of the cause for this versioning issue to come up was the lack of clarity of the namespace for the UWS schema - which is now addressed by the release of a schema with a new 1.1 namespace - therefore it is safe to remove this issue from the UWS specification. Any objections?
