ISSUE-150: Last Call Comment: Subsumption hierarchies


Raised by: Alistair Miles
On product: SKOS

Raised by Erik Hennum in [1]:

We've had a need to distinguish subsumptive relations (for which we
currently use the SKOS broaderGeneric / narrowerGeneric extension) from
broader relations where the broader concept is not fully subsumptive.

For instance, there is consensus in our target audience that the concept of
Linux subsumes the concept of RedHat Linux.  By contrast, the High
Availability concept subsumes the overall purpose but not the operational
tasks associated with the Disaster Recovery concept.  (In passing,
subsumption relations seem much more common between proper-noun concepts
than between general concepts.)

The distinction is important because subsumption is much more reliable for
qualifying content during search applications (and can be treated as
strongly transitive).  Has the committee considered carrying forward this
experimental distinction from the previous version of SKOS as an optional
subproperty of broader / narrower?
