A couple weeks ago (see archives for late January) there was an XML-DEV
thread on conceptual modeling and mapping UML <--> XML schemas.
I wrote in that connection,
"... My guess is that the syntax-centric
stranglehold will not be broken until there's a conscious focus
on conceptual modeling, accompanied by an unspoken agreement
that XML schemas and other markup syntaxes can readily be
generated from conceptual model notations..."
but the comment appeared to have fallen on deaf ears. Most
people are apparently content to design in an environment that
does not test/enforce constraint-based relational semantics
at the object level; using visual-graphical modeling software
and syntax-centric modeling formalisms is "good enough, even
if not ideal..."
For some possibly useful references, see:
"Conceptual Modeling and Markup Languages"
Note the excerpt from Borgida's 1985 paper.
