[Digir-protocol] Re: Multiple schemas

[Nozomi Y. <no...@bi...>]

Dear Don,

> As Anton has mentioned via e-mail

In which e-mail?  How many mail-"societies" are there?

I suggest to use either DiGIR-protocol or DiGIR-dev. list but not both,
depending on talking about protocol or its implementation.  So I'm
sending only to DiGIR-prot. list...

Separation of query schema and result schema (are they agreed terms?)
sounds logically good for me.  However, I wonder that it makes session
between provider and portal stateful; return schema may depend on
providers. The separation also sounds "inclining" so called ANSI three
layer model of DB, because usind different schema in query and return
deferenciate level of abstraction in sense of view and model.

A realistic scenario is having multiple UDDI registry depending on
shema combination, e.g. UDDI registry for DC/DC, for DC/BioCASE,
for DC/EINSIN (and DiGIR meta-regitry giving URI of these
registries?).  In other words, solving schema issue outside of DiGIR
itself.  I'm not sure this will make us happier in total.

Cheeers,
James
