That work appears to be an extension of his 2005 PhD (both Dutch and
English prose), downloadable from here:
http://www.gellish.net/downloads.html (01)
That document references the well-known entities, describes structures
in ways familiar to both the ONTOLOG and topic maps communities, but
does not cite ISO 13250. (02)
I'd like to think, however, that it still serves as a decent overview
of the space. Am I missing something? (03)
