Hi Simon,

Yes, I can see it now. And I realize a lot of imports, and was wondering if they are all import ants…(see http://www.essepuntato.it/lode/owlapi/http://def.seegrid.csiro.au/isotc211/iso19111/2007/crs )

Regarding UMLs, it seems to me that the import rules strictly follow the UML model packages and dependencies (Figure 4, Page 15) of the document at [1] . Am I wrong? With the folks at IGN-France, the first version of the CRS vocabulary we worked on take the core elements within the UML diagram in Page 22,
Figure 6 named "SC_CoordinateReferenceSystem package. (see the attached file)Some harmonization would probably be desirable.
+1 . And this can be done within this CG?
Best,
