Re: OntModel imports not loaded (2.11.0 behavior broken in 3.0.1)

[Martynas Jusevičius]

OK sorry, I meant that the first one imports the second one: gps:
imports gp:. The imports are not cyclic.

Location mapping is not part of the problem, I don't know why I
attached it :) I guess you can just remove all the external imports
(sp:, spin:, foaf:, sioc:) from the ontologies so they're out of the
picture.

Re: OntModel imports not loaded (2.11.0 behavior broken in 3.0.1)

[Andy Seaborne]

So "import each other" is not a cycle?

and does the location-mapping.n3 make a difference because I though  the 
issue was the overridden model.read was not being called which is not 
related to location mapping.

Re: OntModel imports not loaded (2.11.0 behavior broken in 3.0.1)

Is there a way to check whether imports already have been load for an
OntModel? As to call loadImports() only once and avoid calling it with
each OntModel access.
