domain modeling an appropriate approach to message modeling?
[JMC] I would say no.
In
other words, if you want to model a message exchange pattern, would you
use
the same tools you use to model an ontology?
[JMC] Assuming such tools were mutually exclusive regarding their
capabilities (they did not have the capability to model both message exchanges
and ontologies), I would say no. However, the messages that can be exchanged can
be driven by a domain ontology (i.e. "what types of information can/should we
exchange?"), so it would be good if there were interfaces between such tools, or
that a single tool had both capabilities.
Would
you use the same tools you use to model a database schema to
model
a message schema? Would you use the same interview
techniques?
[JMC] Partly - thinking in terms of the message payload vs. the
message infrastructure. The overlap would be for the message
payload.

As I
read the blogs on hi-REST and lo-REST, I keep thinking, one shouldn't
try to
model messages as if they were data, that a messaging system is
orthogonal to a database and that this
is a conceptual impedance at the
heart
of many a tempest in a teapot with respect to the web architecture,
REST,
and SOAs.
