Failed for custom datatype

[LorenzBuehmann]

Tried the 1.0 release on some small DBpedia ABox dataset and got an exception due to a custom datatype (I guess):

Data (dummy.nt):

<http://dbpedia.org/resource/Belgium>	<http://dbpedia.org/ontology/PopulatedPlace/populationDensity>	"363.6"^^<http://dbpedia.org/datatype/inhabitantsPerSquareKilometre> .
<http://dbpedia.org/resource/Belgium>	<http://dbpedia.org/ontology/PopulatedPlace/populationDensity>	"363.58468065625044"^^<http://dbpedia.org/datatype/inhabitantsPerSquareKilometre> .
<http://dbpedia.org/resource/London>	<http://dbpedia.org/ontology/PopulatedPlace/populationDensity>	"5518.0"^^<http://dbpedia.org/datatype/inhabitantsPerSquareKilometre> .

Usage:

java -jar ont-converter.jar -i dummy.nt -o dummy.owl -of MANCHESTER_SYNTAX

Is this not supported yet or already solved in a the newer version of Ont-API? I can see that Ont-Converter still depends on the version 1.4.0-SNAPSHOT

[sszuev]

Thanks for the report.

1. Currently, this project is not maintaining.
   Although there are plans to reanimate the project (and remake it wisely), right now I have no time for it.

2. You are right, this is a bug of ONT-API internal transformers, related to handling custom datatypes.
   It is present even in the up-to-date version.
   Although it can be fixed easily, I can't do it right now.
   As a workaround you can add manually declarations for the http://dbpedia.org/ontology/PopulatedPlace/populationDensity and http://dbpedia.org/datatype/inhabitantsPerSquareKilometre:

<http://dbpedia.org/ontology/PopulatedPlace/populationDensity> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/2002/07/owl#DatatypeProperty> .
<http://dbpedia.org/datatype/inhabitantsPerSquareKilometre> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/2000/01/rdf-schema#Datatype> .

The root problem is fixed in the future release org.github.owlcs:ontapi:2.0.0.

[sszuev]

sure it is fixed in new v2.0 release
