david: Given the above OWL, what inference was made? Need to see the input RDF data, and then see the entailments that result.

Marc: This was obtained how? Inferencing or conversion from XML?

tony: don't care.

marc: seems unusual. I don't see the premises and the conclusion.

tony: Input is 135-139. Important piece is that the type on line 135.
... The inferencing works now, both with named individuals (URIs) and blank nodes.
... I'll show lines 111-122, with the inferred triples in color.

tony: the reasoning works for blank nodes and types. i think the problem was for datatypes.
... But this approach is not scalable because it the ont assertions in IRC above would be needed for all SNOMED terms.
... So I think it should be done as part of the FHIR XML to RDF translation.

rob: Can i try this out?

tony: There are 5 turtle files.

<scribe> ACTION: Tony to upload his 5 turtle files to the hl7 wiki [recorded in http://www.w3.org/2015/05/20-hcls-minutes.html#action01]

rob: Or github would be best.

tony: need to figure out what declarations are required in the RDF instance data payload.

david: You should be able to delete the class declarations and it should work fine as long as the imports are there.
