Duplicating classes when merging

[luisramosbosch]

I am using the lcc ontology to add geo features to Germany.

I was able to add the corresponding geo feature, but found out that the rdf:type reference is being duplicated, I mean in the source ontology there is only one reference to country, while in the output ontology appear two reference to country to the individual Germany:

Here is the template, and I wonder why the reference should being duplicated?

Sorry that you're having problems. There isn't enough information here to debug the problem. I suspect that you are using more than one IRI for "country", but I can't tell from the links you provided.

[luisramosbosch]

this is the command I am using: robot template --prefix "loc: http://www.example.com/" ^ --prefix "geosparql: http://www.opengis.net/ont/geosparql#" ^ --prefix "sf: http://www.opengis.net/ont/sf#" ^ --prefix "lcc-3166-1: https://www.omg.org/spec/LCC/Countries/ISO3166-1-CountryCodes/" ^ --merge-before ^ --input ISO3166-2-SubdivisionCodes-DE.rdf ^ --template geo-de_germany.tsv ^ --output test-germany.owl

actually that seems to be the case, but I am not doing that in the template (or at least i don't think so), and that is the question. I am indicating Germany is of type Country, no more.

[jamesaoverton]

lcc-3166-1:Germany has a single rdf:type in this output, as specified in the template. I also looked in the source ontology you linked https://www.omg.org/spec/LCC/20211101/Countries/Regions/ISO3166-2-SubdivisionCodes-DE.rdf and I didn't see lcc-3166-1:Germany or https://www.omg.org/spec/LCC/Countries/CountryRepresentation/Country mentioned there at all.

[luisramosbosch]

and Germany just exists, thus I wonder if there is another way to create an individual, and relate it to another existing one without producing such unwanted result?.

[luisramosbosch]

lcc-3166-1:Germany has a single rdf:type in this output, as specified in the template. I also looked in the source ontology you linked https://www.omg.org/spec/LCC/20211101/Countries/Regions/ISO3166-2-SubdivisionCodes-DE.rdf and I didn't see lcc-3166-1:Germany or https://www.omg.org/spec/LCC/Countries/CountryRepresentation/Country mentioned there at all.

With regard to this comment, so it is the modular structure of LCC - OMG spec, if I get your point. And, as you say, lcc-3166-1:Germany has a single rdf:type, but the output produces duplicated references, and that is what I wonder: why?.

[jamesaoverton]

Now I see where the other rdf:type assertion is coming from. The type IRI is indeed the same.

So I think that this is just how Protege is displaying the fact that the rdf:type is asserted in the file you're loading (bold) and in one of the imports (not bold). If you merge all the imports and save to a new file, you should not see duplicate rdf:type.

To avoid this, in your template row for lcc-3166-1:Germany try setting the type to owl:Individual or maybe owl:NamedIndividual instead of Country.

[luisramosbosch]

Hi dear, I solved most issues using owl:NamedIndividual and the Country reference to Germany is not duplicated anymore. But, however it continues duplicating the states reference:

which is even stranger, given that I do not mention this identifier in this template.

The template with German states would be like:

CURIE Label Type Comment hasGeometry Geometry ID LABEL TYPE A rdfs:comment AI geosparql:hasGeometry AT geosparql:asWKT^^geosparql:wktLiteral loc:germany-geometry Germany Geometry sf:MultiPolygon Multipolygon representing the Federal Republic of Germany POINT(2.2945 48.8584) lcc-3166-1:Germany owl:NamedIndividual http://www.example.com/germany-geometry loc:Baden-Württemberg-geometry Baden-Württemberg Geometry sf:MultiPolygon Multipolygon representing the german state of Baden-Württemberg POINT(2.2945 48.8584) lcc-3166-2-DE:DE-BW-Subdivision owl:NamedIndividual http://www.example.com/Baden-Württemberg-geometry

Thanks for all your support

[luisramosbosch]

let me know if you need the full ontology

[jamesaoverton]

Maybe it's because you're using owl:sameAs. I would avoid that if possible.
