RE: Belated comments on SPARQL Protocol for RDF 25 January 2006 LC WD

Dan,

Is the query operation supposed to be safe? 

<operation name="query" pattern="http://www.w3.org/2006/01/wsdl/in-out">

You have two HTTP bindings for it, GET and POST. Doesn't this violate Web 
architecture? If the operation is safe, it should be bound to GET. If the 
operation is not safe, it should not be bound to GET. Seems like binding 
the same operation to both GET and POST should never happen. Or are you 
leaving it up to the user? Does the safety depend on the actual query, 
i.e. some querys do updates (I have read the SPARQL spec) ? If so, having 
both bindings does make sense.Thx.

BTW, there is a WSDL extension attribute wsdlx:safe [1] You can use that 
to mark on operation that is known to be safe, in which case it would be 
bound to GET.

We passed the Woden validator today.

See details:

wsdl fun (re: ACTION: LeeF to try SPARQL WSDL files with Woden
validator, report results.) Lee Feigenbaum (Tuesday, 21 March)

In particular, this WSDL file:

http://www.w3.org/2001/sw/DataAccess/proto-wd/sparql-protocol-query.wsdl
1.18 2006/03/21 19:18:07

I hope it's good enough. We did not change maxOccurs nor the name thing,
but indications I'm getting are that the WSD WG is OK with that.
