[tdwg-content] Question about "vocabulary" in Darwin Core Archives assistant

[David Remsen (GBIF)]

Hi Steve,

There is a way to do what you ask but not exactly the way you specified.

The way to do is via a template that refers to a particular column.  
So if you put the ubio integer ID into dwc:scientificName you could could put the following into, for example, dc:source

http://www.ubio.org/authority/metadata.php?lsid=urn:lsid:ubio.org:namebank:<scientificName>

as the default and set the column to a global.

You can see more in this document on the XML Descriptor file.

http://links.gbif.org/gbif_dwc-a_metafile_en_v1/

The vocabularies option was, as far as I know, intended to provide a URI for a vocabulary so that we might be able to validate values against the vocabulary items.

Best,
David
