Hi Geoffrey,
There is (currently) no elegant solution to publish multiple vernacular names in simple DwC, it is one of the limitations of simple DwC.
It is however possible to publish multiple vernacular names (and their language and some other information) if you use extensions. There is even a official GBIF Vernacular Name extension: http://rs.gbif.org/extension/gbif/1.0/vernacularname.xml. This extension is a text file where every line is a vernacular name, with a link (via an ID) back to the core file, containing the specimen information. More information here: http://code.google.com/p/gbif-ecat/wiki/DwCArchive
However, this extension was intended for the use of species checklists, with a TAXON core file. I don't think it has ever been used to link to an occurrence/specimen core file. I do know that some herbaria record vernacular names on a specimen level, but that is not really best practice, since vernacular names are in fact properties of taxa, and only by relation of specimens: Alpine alumroot and heuchère glabre are vernacular names for Heuchera glabra, and thus of every living or preserved specimen of that species (http://data.canadensys.net/vascan/name/alpine%20alumroot).
If you want to see an example of a checklist Darwin Core file using a vernacular name extension, we created one for all the vascular plants in Canada (might be useful for your herbarium): http://data.canadensys.net/vascan/dataset You can also search and create your own Darwin Core files for Canadian plants using our checklist builder: http://data.canadensys.net/vascan/checklist
Hope this helps,
Peter

Greeting, I have recently begun the process of digitising the 60,000 specimen vouchers from the UNB herbarium. The textual data for 40,000+ of those has already been entered into a database, and I am now trying to map those values to DwC so that we may share the data with other collections. I have some concern over the fact that simple DwC does not allow the repetition or extension of certain fields. The vernacularName field is a particular problem. New Brunswick is Canada's only officially bilingual province, as such, our specimens are all identified with both their English and French common names in the database. It would be very useful if we could extend DwC, creating something along the lines of <vernacularName lang=en>, or allow nesting of elements, perhaps in the form:
<vernacularName> <English>Chives</English> <French>Ciboulette, brulotte</French> </vernacularName> The other option, as I see it, is that we store the English and French common names in our own fields, and then concatenate the two to create the DwC:vernacularName field. I see this option as less than ideal since it may hinder search/browsability. It may also cause a host of other problems from interpreting to storing the data. The herbarium with whom we first intent to share the data has already expressed a concern that their system cannot handle the diacritics found in many of the French names (!). They would like the Eng. common names, but not the French. This is more difficult to achieve if we concat the values. One additional thought is that the herbarium's imprint, _Flora of New Brunswick_, also includes common names in Maliseet and Mi'kmaq wherever possible. Although these two aboriginal languages do not currently exist in the dataset we are using, there is the potential that they may be added at some point in the future. It seems to me that the repetition of fields may be necessary in other instances too. I am having some difficulty figuring out how to record all the location data we have for the specimens, which are indicated using verbal descriptions, Lat/Long, UTM, and NTS coordinates - in many cases using all 4 for a single sample, but I will save the details for another posting. I will watch for the group's thoughts on this problem.
