Multilingual ont: prefLabel is generated from URI fragment and displayed under 'none:' for terms that do not have English lang tags

Multilingual ontology support:

prefLabel gets generated from URI fragment and displayed under 'none:' for terms that do not have English lang tags

<!-- http://www.semanticweb.org/ontologies/2009/3/ontoDPN.owl#AttributObjetPhysique -->
     <owl:Class rdf:about="&ontoDPN;AttributObjetPhysique">
         <rdfs:subClassOf rdf:resource="&ontoDPN;Attribute"/>
         <DOE:swp rdf:datatype="&xsd;string">internalised point of view on abstract objects</DOE:swp>
         <skos:definition xml:lang="fr">Attributs s&apos;appliquant à des objets physique</skos:definition>
        <skos:prefLabel xml:lang="fr">attribit physique</skos:prefLabel>
     </owl:Class>

Is this the expected behavior? If the term is in French or in German, do we really need non-french generated perfLabel?

The question here, is in the UI, what do you want to display as prefLabel if there is no English values:

1. Arabic, Chineese, French or anything that is provided. (you will be in this situation https://github.com/ncbo/ontologies_linked_data/issues/91)
2. Or instead using its id (URI fragment) as its prefLabel.

the none here means, that the generated value has no language tag.

And the "none" is the official syntax that JSON specifies for this.

This is also related to the "default" language discussion in the other tracker : https://github.com/ncbo/ontologies_api/pull/149

In many cases, the perfLabel generated from the URI fragment has no inherent meaning; frequently, they are alpha-numeric term ids, which may not add any value and could potentially cause confusion.
