Wine ontology no longer loaded #26

Closed steffen-l closed 7 years ago

steffen-l commented 7 years ago

Compare installation of NEW OWL2VOWL: http://visualdataweb.de/webvowl/#iri=http://www.w3.org/TR/owl-guide/wine.rdf with OLD OWL2VOWL: http://vowl.visualdataweb.org/webvowl/#iri=http://www.w3.org/TR/owl-guide/wine.rdf

While it is visualized in the first, it is not in the second. Instead, the "loading ontology..." message is shown endlessly.

Bug in OWL2VOWL. The producesWine property has the inverse "hasMaker". HasMaker does not have a domain and range and is in owl2vowl not reference by any other property and therefore not exported to json. To fix this we have to add any reference (inverse, etc) to the corresponding array of the property.

Also, other ontologies cannot be loaded with the new version that could be loaded with the old one. The same effect ("loading ontology..." message is shown endlessly), leaving the user with no idea why they cannot be loaded.

Here are some examples (incl. links to the old and new version of OWL2VOWL + WebVOWL):
