To give an example.
As far as I can think we might end-up with a framework of Context's.
Each Context is a sub-domain model with its own set of Concepts, Terms and
In any (medical) document each one data item will be surrounded by Tags
relating to each of the 6 Context subdomains.
Several parts of the sub-domains can be coded according to several
codingsystems. Each with its own DTD.
SO it can be that there is one FrameWork-DTD and several optional DTD's in
each subdomain model.
In general I can see a FramWork of 6 SubDomains (Context's)
- Real World Place, things, people, etc
- Document World author, owner, etc , etc
- Narrative World the way we tell or write stories
- Topic Model World In the case of medine : diagnosis, findings,
- Legacy systems
- Business world Protocols, worlkflow
In the case of medcine I would call it : MeSpeak
