Title: Message
I did
one of those for UBL about 16 months ago. See the attached (and perhaps
oddly named) UMLModel.xsd.
At
that time, I used to load the UBL model (spreadsheet) into Excel (the new
version -- that outputs XML) and then I'd save it as XML. I used the
attached stylesheets to convert from Excel's proprietary vocabulary into the
"UMLModel" one by running them in this order:
fatten-excel -> spreadsheet-to-UML-model-no-asoc ->
resolve-association-ends -> define-associations
normalize-identifier is a utility called from the other
transforms.
The
value I saw of this over XMI was that the vocabulary was more tailored to the
modeling language we'd chosen for UBL -- so there was a tighter fit. Also,
the vocab is considerably smaller (though less well documented :) than XMI so it
was presumably easier to learn.
I've
got some additional pipelines that fit on the end of this one to generate
pictures of UBL too. Well, _old_ UBL.

Subject: [ubl] A
Prototype Schema for UBL Models
I wonder if this will be of interest to the UBL
TC.
This was discussed a while ago in an ISC
meeting.
I've prototyped a Schema for the UBL models,
based on the ccts:CoreComponentsParameter Schema Module, which it
imports.
(both attached)
I guess it could be used as an alternative means
of storing the model
data in a non-proprietary (XML) format from
which it could be
transformed, perhaps into a variety of other
formats, including
Schemas, perhaps forms and even perhaps class
diagrams.
Of course it could be transformed to and from
spreadsheets too and
other proprietary formats. As such it could be of
interest to tools
but it might help towards solving
customization/context problems too
with regard to autogeneration.
All the best
Steve
