John (cc'ing the GRDDL WG list),

As per our last conversation, I was hoping if you can help us with the
"killer" GRDDL use-case you were talking about earlier. In particular,
the use-case I believe has a patient going to the doctor twice, and so
filling out two different HL7 CDA documents, both in XML. On his first
visit, he records that he is allergic to a particular family of drugs.
On the second visit, he forgets that he is allergic to this family of
drugs, and so his second HL7 CDA document does not record this. A doctor
prescribes him a drug on the second visit, unknowingly a drug that is a
subclass of the family of drugs the patient is allergic to by virtue  of
its properties.

Yet the hospital can automatically catch this error and save the
patient's life by converting both HL7 documents via GRDDL to RDF, and
merging them. Therefore the old data about the patient being allergic is
not lost, but discovered.

Furthermore,  because the family of drugs is kept in an ontology, some
sort of simple OWL entailment can show the drug the doctor prescribed is
a subclass of the drug the patient said they were allergic to.

John - this piece would be a rewrite of piece of the Primer Chime
already wrote. I'm happy to write the prose if you can produce another
HL7 document that describes this sort of use-case, and feel free to
modify anything , including data files, (all files are linked from the
