First of all, a fantastic tool!
I played with it today making ontology.
I noticed issues in generated ontology if I use "
/" instead of "
#" for entities IRIs.
Code for IRIs which use "/":
onto = get_ontology("http://knowledge.graph/wind/")
define_datatype_in_ontology(VestasNaming, "http://knowledge.graph/wind/VestasNaming", onto)
class DO(Thing):
namespace = onto
class notation(Thing >> VestasNaming):
namespace = onto
HorWdSpd = DO("HorWdSpd", namespace = onto,
label="Horizontal Wind Speed",
comment="IEC data object instance for Horizontal Wind Speed")
HorWdSpd.notation.append(VestasNaming("WindSpeed"))
onto.save("./ontology.xml")
which results in
<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

<wind:notation rdf:datatype="VestasNaming">WindSpeed</wind:notation>
</wind:DO>
</rdf:RDF>which when loaded to Protege results in two DO classes instead of one. One of those DO classes has correct IRI but no instances/individuals related to it, the second one with an IRI equal to the filepath to onotology (i.e., wrong IRI) has a HorWdSpd individual related to it.
However, if I use "#" instead for IRI entities (e.g., base_iri#ClassName):
onto = get_ontology("http://knowledge.graph/wind")
define_datatype_in_ontology(VestasNaming, "http://knowledge.graph/wind#VestasNaming", onto)
class DO(Thing):
namespace = onto
class notation(Thing >> VestasNaming):
namespace = onto
HorWdSpd = DO("HorWdSpd", namespace = onto,
label="Horizontal Wind Speed",
comment="IEC data object instance for Horizontal Wind Speed")
HorWdSpd.notation.append(VestasNaming("WindSpeed"))
onto.save("./ontology.xml")everything works as expected and resulting XML is correct:
<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

<rdfs:comment rdf:datatype="http://www.w3.org/2001/XMLSchema#string">IEC data object instance for Horizontal Wind Speed</rdfs:comment>
<notation rdf:datatype="#VestasNaming">WindSpeed</notation>
</DO>
</rdf:RDF>which when loaded in Protege result in a single class DO, and HorWdSpd instance of it.
Is there anything I should do to make sure that entity IRIs which use "/" work properly when ontology is exported to XML?
