Worth pointing out that Lexvo was used by the BL in their recent RDF modelling exercise: http://www.bl.uk/bibliographic/datafree.html

Thank you.

Similarly, ISO 639-2B is more or less a subset of the languages represented in ISO 639-3:  languages of literary warrant having passed a threshold of being used in fifty or more texts.  MARC language codes in many cases still carry an outdated colonial legacy:  uv for Burkina Faso (the former Upper Volta), rh for Zimbabwe (Rhodesia), dm for Benin (Dahomey).

With my Semantic Web/RDF hat on: RDF has made the choice of (1) use Unicode ("The lexical space of a datatype is a set of Unicode [UNICODE] strings."[1]) and, if needed, the language tag (the 2004 version of RDF referred to rfc 3066, the new one in preparation relies on bcp47[2]). I would think that the combination of these two should provide a standard for interchanging data; even if a particular language or script is not present in the current standards, these are evolving, so by sufficient peer pressure (and the library community has the possibility to provide such a pressure) any missing entry could be added, eventually.

I can imagine that, in some cases, you would need a richer description of the language involved, eg, for a human reader. This could be incorporated into an RDF based vocabulary using existing ontologies and URI references. The one I know just a bit is lexvo:

http://www.lexvo.org/

that provides URI-s for languages, as well as some description that can be linked to. For example, if I take Hungarian, it provides a URI for the language:

http://lexvo.org/id/term/hun/

there is an RDF representation for this URI which links further to a more detailed information (through the http://lexvo.org/ontology#language property) to:

http://www.lexvo.org/page/iso639-3/hun

which then includes further information about Hungarian (essentially the various labels of the language in different languages).

The beauty of the Linked Data is that, from the library community point of view, there is no need to repeat this information; you should just link to it and let other people feel the pain of keeping that data up to date...

I hope this answers your question!

Cheers

Ivan

P.S. I am not an internationalization expert, but I have a colleague at W3C (Richard Ishida) who is really really knowledgeable in this. Some of the services he provides on his web page may be helpful here (see [3] or [4] for language tag and unicode lookup), and his page on the W3C on the language tag may also be interesting...

This has been documented in a report of a W3C Incubator Group[2]; they have made a much better job that I would ever do. However, I can express why I believe such a synergy would also be beneficial for the Semantic Web community. Indeed, the Semantic Web envisions a Web of Data, i.e., a place where different types of data can be integrated, used by applications or by end users, regardless of the origin and the exact location of that data. The Web has given us this for documents; it is time to have the same for data in general. However, it is inconceivable to envisage this without the huge amount of data, repositories, catalogues, accumulated knowledge, etc, that is available in libraries around the globe. Furthermore, and that may be less obvious to the library community, the unique experience that this community has in cataloguing, archiving, and managing resources can bring a hugely important extra experience and knowledge to the Semantic Web community, research and development alike.

However, I would be very pleased to provide feedback, whenever that is necessary, on specific, Semantic Web related technical questions concerning the intricacies of RDF, OWL, SKOS, or SPARQL. I would also be happy to take the problems raised by this group and feed them back to the relevant Working Groups that are currently active at the W3C (see, for example, [3] for some of those). I.e., I hope I can be of help.
