[OAI-implementers] SOAP-PMH

[Hussein Suleman]

hi Jeff, Tim, et al

i agree - consensus is the issue here. there are certainly many 
different ways to encode OAI-ish data into SOAP envelopes. it shouldnt 
be too difficult to set up a process to decide on a single 
interpretation, but that should be within the auspices of the OAI (if it 
still exists) and, more importantly, i think we should put effort into 
it only if people think there is real benefit in doing it right now!

as a counter-argument, the dust on SOAP1.2 has yet to settle and WSDL is 
not yet a W3C recommendation ... alternatively we can adopt the WSI 
interpretation of Web Services, which does not rely on W3C 
standardisation but builds on the technical notes. all very political 
and complicated stuff indeed :)

in any event, if the technical stuff isnt a big deal then the pertinent 
question is: how do users (people who code their own data providers and 
harvesters) feel? is there a need to look at SOAPifying OAI-PMH at this 
point in time?

ttfn,
----hussein

ps. yes, Tim, you can easily create a layered SOAP/OAI system (see the 
paper at ECDL2004) ... and, yes, you can include the ANY bit because you 
can really include anything that XML Schema allows ...
