Two Problems with the Model Transformation to OWL with gUFO

[italojsoliveira]

@matheuslenke, I want to report two problems with the model transformation to OWL with gUFO:

1. No title property (dcterms:title, rdfs:label or sdo:name) is created - for the whole ontology. The generated ontology has no title. Tools like PyLODE need a title to work. This can be fixed manually at the beginning of the .ttl file. However, the ideal solution would be to prompt plugin users with a field for the ontology title.

2. A more subtle issue occurs with certain automatically generated relations, particularly those representing UML composition. They are created without any rdfs:label, which again breaks certain applications. Check my .ttl file as an example:

:userExperienceHasPhysicalUserBehavior rdf:type owl:ObjectProperty;
rdfs:domain :UserExperience;
rdfs:range :PhysicalUserBehavior;
rdfs:label "userExperienceHasPhysicalUserBehavior"@en. # <-- Added rdfs:label .
:userExperienceHasVirtualEvent rdf:type owl:ObjectProperty;
rdfs:domain :UserExperience;
rdfs:range :VirtualEvent;
rdfs:label "userExperienceHasVirtualEvent"@en. # <-- Added rdfs:label .

I had to find those relations observing they lack labels, then adding rdfs:label.

The obvious solution is to implement rdfs:label for those generated relations or other similar cases.
