Labels in more languages

[Zack-83]

This pull request is a teaser to make QUDT really international and applicable in more languages. The proposed denominations for quantity types and units have been checked with the help of many mother tongue scientists and of Wikidata.

Thanks. This is great. However, user interfaces will need to be more clever to highlight (?) the label in the best language for the context ...

The lack of multiple languages has been a holdup in using this data for UI's. I support this type of additon.

for all other languages: Wikidata + some understanding (I am fluent in Italian, German, French, Spanish)

Thanks so much for your efforts. I see that you are only covering a small percentage of our quantity kinds and units. In order to scale this to the full vocabulary, might I ask how you went about generating the labels that you have done so far? We are assuming you did not do this manually. If that were the case, we would need to go back and do a bit of quality assurance.

Dear Steve Ray,

This was approximately the procedure I followed:

• I focussed on the quantity kinds and units listed in the ISO 80000 norm, but expanded it.
• I searched as many labels as possible with a SPARQL query on Wikidata.
• For the languages for which I could find support, I let mother-tongue friends/colleagues check and complete the labels.

Each of these methods has advantages and disadvantages:

• Wikidata: big data base, machine actionable (--) no guarantee for coherence
• ISO norm: official denominations (--) not complete
• mother-tongue experts: flexible, communicative (--) not automatic

@Zack-83, one thing that slipped my notice on this PR was that you occasionally added multiple rdfs:label entries with the same language tag. That upsets some tools. Could I ask you to do another PR where you leave the preferred label as rdfs:label, and move any duplicates to triples with skos:altLabel?

OK @steveraysteveray , I tried in this new PR: https://github.com/qudt/qudt-public-repo/pull/784
