[bioontology-support] Problem with HRDO multilingual label

Dear BioPortal team, 


Looking into an issue on one our AgroPortal OWL ontology that have label
defined in skos in multiple language we figure out a bug that is in fact
happening in the NCBO BioPortal e.g. on HRDO


Why is this concept prefLabel Spanish
_links=false> &display_context=false&display_links=false


Where as this one is in French
nks=false> &display_context=false&display_links=false


And other will be in English.


While BioPortal is not multiligual (yet!) everyone assume that if a
multilingual ontology is uploaded, only the english labels will be display
in the tree (or as defaultprefLabel).


The issue seems to come from the fact that multiple skos:prefLabel are
defined with different languages e.g.,


<owl:Class rdf:about="&hrdo;typ_id_17">

        <rdfs:label xml:lang="en">biological anomaly</rdfs:label>

        <rdfs:subClassOf rdf:resource="&hrdo;typ_id_4"/>

        <skos:prefLabel xml:lang="en">biological anomaly</skos:prefLabel>

        <skos:prefLabel xml:lang="fr">anomalie biologique</skos:prefLabel>





The ontology has for perfLabelProperty skos:prefLabel



I think this is not happening with OWL ontologies using multiple rdfs:label

To be double checked.



The problem is propagated to the Annotator that match only the terms
selected as prefLabel

It means that a text with “anomalie biologique et biological anomaly” this
is the French expression that generate the annotation



The problem is not propagated to the Search service that uses all the
properties of classes

E.g., a search for “Eales disease” does return the class “

Enfermedad de Eales”



Protégé parse the ontology properly, without mixing the languages


Could you look into this issue or tell us where to look at to fix the
problem ?


Al the best
