that would be true, if it were true... in the current release of openEHR, ADL/AOM 1.4 only implies that such bindings should obey a subsumption relationship. In the ADL/AOM 1.5 specifications this is stated, but it can only be formally enforced within an archetype if some formal subset relationship could be asserted between distinct subsets (say, 'all bacterial infections' and 'all bacterial lung infections'). As far as I know, such a relationship, while mathematically easy enough to define, is not recognised in any of the machinery associated with current terminologies or products, so we will have to wait a bit longer for that. - thomas beale * * -------------- next part -------------- An HTML attachment was scrubbed...
