[topicmapmail] ORM of XTM

[Tony.Coates@reuters.com]

I've been playing around with a beta version of a Microsoft tool for ORM (Object Role Modelling, http://www.orm.net/), which is alternative to UML that many people are finding preferable when building data models.  As an exercise, I have built a (rough draft) model of XTM 1.0 (more precisely, of my reading of XTM 1.0), and I thought I would post it to see if anyone else thinks it is informative.  I don't want to explain the notation here, so write to me directly if you have questions.  You will quickly see how there is a bit of a topic-map feel to ORM.  The report document is generated from the diagrams using the association labels, and is a convenient way to present a checklist of the "facts" (assertions) in an ORM model.  I'm sure something similar could be done for topic maps.

     Cheers,
          Tony.

PS  Let me know if you want the Visio Modeler source files, or if you have suggestions/corrections.
