Dear Bill, I gave a paper on 'the immunological model of access' control at the HL7 CDA conference last year in Berlin. It is to be found at http://www.hl7.de/cda2002/progoverz.html , the last paper. The power point version does not load well from this site, and is found at my own web page at http://www.eyetech.co.nz/?page=ehr.inc (but it takes a while to load). Interestingly, a presentation from Finland at the same conference had almost the same idea, although the access control aspect was not quite the same. The proposed mechanism, based on a concept from immunology, would also work for a simplified version of the Openehr architecture. I think the model has the potential to facilitate a global ehr and access system.
