[bioontology-support] Problem with HRDO multilingual label

Hi Clement, 

Nice to hear from you on HRDO. I have had many issues with lang tags in bioportal. 
I do not understand the behavior of the browser (which label is chosen). 
I was suggested to create views, for each langage. I must admit I didn’t went into this.

For example, in the ontology file you have this :

    <owl:Class rdf:about="&hrdo;typ_id_6">
        <rdfs:label xml:lang="en">group of diseases</rdfs:label>
        <rdfs:subClassOf rdf:resource="&hrdo;typ_id_0"/>
        <skos:prefLabel xml:lang="en">group of diseases</skos:prefLabel>
        <skos:prefLabel xml:lang="fr">groupe de maladies</skos:prefLabel>

And in the browser you have this (the label in the tree is french, don’t know why) :

However in HRDO v2, rdfs:labels are english and I used skos:prefLabel / altLabel to support the 6 langages of the ontology. 
Please let me know if I can be of any help to you or to the bioportal team.

Best regards,

I've created a ticket to track this issue (NCBO-1662 - An incorrect prefLabel is chosen when multiple language prefLabel(s) are defined). We'll do our best to address it in a timely manner.
