Observable entity foundation reference set

This reference set supports the recording of observable entities, such as the ability to communicate, in Australian e-health implementations. It can be used:

· within implementations where use-case specific reference sets for observable entities are yet to be developed

· as the basis for developing further use-case specific reference sets for observable entities, through a process of constraint

· as a benchmark, against which use-case specific reference sets developed by the SNOMED CT-AU user community can be tested to assure that they are logical constraints of the content for observable entities.
