Dear all,

In the version 1.2 PDF [1] on page 10, it says that SP5 Geometric Place 
Expression is a subclass of E94 Space Primitive. This allows it to be 
referenced using P168 place is defined by.

However in the RDF encoding for CRM core, E94 is mapped to rdfs:Literal which 
cannot also be used as a subclass with E73 and E47. This is reflected in the 
RDF for CRMGeo by simply not including E94 as a subclass.

So … the abstract documentation and the RDF mapping are significantly 
inconsistent. Can an SP5 be used as the object of a P168 relationship (and 
hence the mapping should be updated to include it) or not (and hence the 
documentation should be updated to remove it)?

Many thanks!

Rob
