[OAI-implementers] Requesting a part of a record possible wit h OAI-OMH?

[Hussein Suleman]

hi Andy

it looks most interesting ... here are some thoughts:

- your descriptions are for an independent external registry, while i 
was proposing a "friends"-like services offered on the same archive. as 
such, "title" would be a moot point, while you (rightly) require it.

- your service identifiers are assigned by a central authority - with a 
self-description, that should not be necessary (and may even violate 
some information independence principles)

- you do not have a formal identifier for the protocol and i think that 
is quite important to match clients and servers for services. i was 
suggesting the canonical URI of the protocol specification. if someone 
comes up with a new CGI-based protocol, they SHOULD have a specification 
written down somewhere, otherwise i don't see the point of advertising 
the interface publicly.

- WSDL is tricky. did you use the draft spec or the technical note? 
there are encoding differences between the two, so until this becomes a 
standard, i am keeping my distance.

- access rights may be useful. administrator may be covered already (by 
adminEmail). contributor is again not relevant in this case, but i see 
that that is optional anyway so it doesnt matter.

so ... do you think these differing requirements can be merged? (im 
still not sure where/how i will use this yet, but at least a few other 
seem interested as well).

ttfn,
