Hi Lei,
Do you have this problem with all OBO ontologies, or just a
particular one?
The list of properties is restricted to object or data (or both)
properties according to whether you select Class, Individual or
Free-Text - but it shouldn't restrict according to a particular class.
The properties are used to create the predicate between the cell and its
populated content when generating RDF triple. Currently you can only
select one. Maybe it should allow selecting multiple which will then
lead to multiple triples?
thanks
Stuart.
