Subject: RE: [soa-rm] Good Recent SOA Piece: "Managing an XML Data Model In Your SOA - Best Practices"
The problem with “canonical data
model” is that it does not scale with time. Eventually it will not
canonicalize but constrain the richness of communication that is expected among
various SOA entities. IMHO SOA data mode should aim to define
(a) the interfaces used by SOA entities to exchange information, (b) mechanisms
to discover these interfaces and (c) mechanisms to negotiate a
vocabulary/format for data exchange over these discovered interfaces. Vikas From: Chiusano Joseph
[mailto:chiusano_joseph@bah.com] I think some additional context may not
have been provided below. While the article does state "This article does
not discuss how to integrate data models", it is stated in the context of
"this article will not get into this topic because it is either out of
scope or too complex to discuss". The author is actually a strong proponent of having an
integrated data model, as they depict an integrated data model as one of the
layers of their approach. I interpret this as a "canonical data
model", which is a special type of data model used for data exchange. Joe From: Frank
