RE: technical issues for vocabs: xml:lang and which skos:*Note tag to use

I have updated the A&A, AOIM, and UCD vocabularies to use xml:lang. Please find the updated files available from http://explicator.dcs.gla.ac.uk/Vocabularies/

Cheers,

Alasdair

Two questions below, which I probably should have sent in different emails.

Doug

1. use of xml:lang attributes

Rick's IVOA thesaurus (as do the vocabs from Explicator) includes entries like

<skos:Concept rdf:about="#accretionDisks">

<skos:prefLabel>accretion disks</skos:prefLabel>
<skos:definition>accretion discs UK</skos:definition>
<skos:definition>accretion disks</skos:definition>
   ...

I think it would be good to add xml:lang attributes, so in this case we'd have

<skos:prefLabel xml:lang="en">accretion disks</skos:prefLabel>
<skos:definition xml:lang="en-GB">accretion discs</skos:definition>
<skos:definition xml:lang="en">accretion disks</skos:definition>

Or, if I actually read http://www.w3.org/TR/xml-i18n-bp/ then we'd have

<rdf:RDF .... xml:lang="en">
...

<skos:prefLabel>accretion disks</skos:prefLabel>
<skos:definition xml:lang="en-GB">accretion discs</skos:definition>
<skos:definition>accretion disks</skos:definition>

Is there any reason why we shouldn't add this to the vocabs?

[AG] In fact, if you read the SKOS Core Guide you will find that there is a section about using multilingual labels and it uses your suggested xml:lang attributes. On my behalf it was sheer laziness or oversight that they are not included at the moment. I will edit my generating script to add these in for the AOIM, A&A and UCD vocabularies.

b) what skos:*Note should be used?

Rick's IVOA thesaurus uses skos:scopeNote for adding "extra" information. The skos guide at
http://www.w3.org/TR/swbp-skos-core-guide/#secdocumentation suggests we should split this up and use one of

  skos:scopeNote
  skos:historyNote
  skos:editorialNote
  skos:changeNote

I can go through and produce a first draft for this (ie how I feel the labels should be placed) if that would be useful. Received on 2007-11-27Z13:42:03
