This is already available in a comparable protocol under development by 
the Z39.50 community: SRU - Search/Retrieve URI service 
(http://www.loc.gov/z3950/agency/zing/srw.html#sru). SRU is SRW 
mentioned by Herbert in his last message, where SOAP is replaced by HTTP.

I would applaud if the Z39.50 (http://www.loc.gov/z3950/agency/zing) and 
the OAi initiatives were coordinated.

In one of my implementations of OAi-PHM it is possible to use a query 
attribute in the HTTP request. The resumptiontoken implementation is 
based on a already existing result set mechanism. These are the elements 
needed to implement a SRU server.Adding SOAP and the SRU server is a SRW 

My suggestion is that SRW becomes (in time) a richer version of OAI-PHM 
(or that OAi-PHM becomes a subset of SRW).
