Hi There,
I'm wondering whether there is a parameter I can set when loading ontologies to request them in a specific format. I am currently having an issue loading the
W3C Time ontology (and similarly, loading other ontologies that import the time ontology), because it seems that the IRI dereferences to a turtle file by default. See below for an example.
I can get around this issue when loading the time ontology individually by specifying a ".rdf" extension, but this does not resolve issues when loading ontologies that reuse the time ontology with its standard IRI. Has anyone run into this? Any suggestions on how I might resolve it?
Thanks in advance!
