Please be very careful with the use of the "Administrative Language"
information from ISO 3166-1.  It is incomplete and therefore not good data.
For example, it shows only two "Administrative Languages" for India where
there are at least twenty-two.  I am hoping that this information will be
taken out of the standard in the near future.  I am currently writing an ISO
NWIP for a revision of ISO 3166-1 which will include a proposal for the
deletion of this data.

Hi Misha,

We are very aware of it, and have been following the work, but I failed to
mention it in the email.  I should say that our ontology was developed for
offline use in an internal system, as an initial requirement.  Having said
that, if you look at the RFCs, they only describe tags, not an RDF
vocabulary or OWL ontology.  Our approach is compatible with the RFCs but
adds capabilities that support co-reference resolution, for example, in
target application.

Hi Gauri,

We've done this for some of our government customers, using essentially the
second approach you cite.  We're also in the process of relating the
ontology to another one we've built to represent ISO 3166, which includes
the administrative languages used by countries and non-sovereign territories
represented in that standard.

If you can hang out for a few days, we (Sandpiper) are just finalizing a
version that includes both ISO 639-1 and 639-2. The approach is more of a
hybrid of the two you present, based on customer needs.  It includes a
fragment of ISO 1087, and also some inverse relations since there is a
one-to-one correspondence between languages and codes.  We elected to create
a 'Language' class, rather than 'LanguageCode', which we reuse in other
applications; classes for Alpha-2Code and Alpha-3Code are subclasses of
CodeElement, from ISO 5127, with instances of these codes as first class
individuals. We use literals (via datatype properties) to represent the set
of English, French, and in the case of 639-1 Indigenous names.  We've also
created subclasses of Alpha-3Code to support distinctions between
bibliographic and terminologic, collective, and special identifiers, with
individual and macrolanguages to support 639-3.  A subsequent release will
include all of the languages described in ISO 639-3, as well as additions to
support at least some of the subtagging that Dan mentions, fyi.  Our intent
is to publish it on a new portal that will become part of a new service
offered by the Ontology PSIG in the OMG, since we've been asked to publish
several ontologies in recent RFPs.  I'll be happy to send our preliminary
version when it's "baked and tested", and follow up with an announcement of
the new portal (where a revision using OMG URIs will be posted) once that's
available.  It may be a couple of months before we're ready to make that
announcement, but we're hoping that the service will be useful to many of us
in the Semantic Web community.

Best regards,

Forwarding from the Dublin Core list, in case folk here can advise. 

Gauri, one thing I'd suggest as useful would be to take the concepts
implicit in RFC 4646, 

see also

...and in particular the subtag mechanism, script, region, variant etc. 

It would be great to have those expressed explicitly. 




Language Ontology

"Salokhe, Gauri (KCEW)"  <mailto:Gauri.Salokhe@FAO.ORG>

Dear All, 

We are working on creating Ontology for languages. The need came up as we

tried to convert our XML metadata files into OWL. In our metadata (XML)

records, we have three types of occurrences of language information. 

<dc:language scheme="ags:ISO639-1">En</dc:language>

<dc:language scheme="dcterms:ISO639-2">eng</dc:language>


We have two options for modelling the language ontology:

1) Create a class for each language, assign URI to it and add all the other

lexical variations, ISO codes (create datatype property) as follows:


|_ Class:Language

	|_ Instance:URI1

		|_ rdfs:label xml:lang="en" English

		|_ rdfs:label xml:lang="es" InglÚs

		|_ rdfs:label xml:lang="it" Inglese

		|_ rdfs:label xml:lang="fr" Anglais

		|_ etc.

		|_ property:hasISO639-1Code  en (string)

		|_ property:hasISO639-2Code  eng (string)

		|_ etc.

	|_ Instance:URI2

	|_ Instance:URI3

	|_ Instance:URI4

2) Create Classes called Language and Language code and make links between

instances of Language and Language Codes as follows:


|_ Class:Language

	|_ Instance:URI1

		|_ property:hasCode  en  (link to the en instance of Class

ISO639-1 below)

		|_ property:hasCode  eng  (link to the eng instance of Class

ISO639-1 below)

|_ Class:LanguageCode

	|_ SubClass ISO639-1

		|_ Instance:en

		|_ Instance:fr

		|_ etc.

	|_ SubClass ISO639-2

		|_ Instance:eng

		|_ Instance:fra

		|_ etc.

	|_ etc.

Does anyone have similar experience with modelling in OWL? Any suggestions

which model is better and (extensible)? Does an ontology already exist that

we can reuse?

Than you,
