SNOMED CT RF2 & ref sets - UML and meta-data diagrams

Technical (archive)
1

As part of reviewing SNOMED CT Release Format 2 (RF2) and Reference Sets specifications, I have created some diagrams which are available here: http://www.openehr.org/wiki/pages/viewpageattachments.action?pageId=10387459

So far I have a class diagram, and semantic net diagrams of the SNOMED meta-data hierarchy. The latter is really a meta-model hierarchy, used to define the model of other parts of Snomed.

I am still refining the original .vsd, but it is available if anyone wants it.
