In Audubon Core [1], there are sometimes other terms that are
associated with a string term whose purpose is to indicate the
controlled vocabulary being used in the other term (e.g.
Iptc4xmpExt:CVterm for a controlled value term and
ac:subjectCategoryVocabulary to indicate the vocabulary from which the
controlled value term comes). I reviewed the DwC terms and I guess
there is no precedent for that kind of thing in DwC. I suppose if
people want to be unambiguous, they should just use URIs.
Unfortunately, I'm not aware of URIs for the terms from various systems
of describing biomes. I suppose someone could mint terms if they cared
about this. Or use ENVO uris.<br>

<pre wrap="">The other thing I'm wondering about the values of dwc:biome would be how a
user would indicate the controlled vocabulary one is using. The ENVO
ontology is mentioned. Under the scenario of the draft RDF guide, the term
dwcuri:biome would have a URI value of
<a class="moz-txt-link-rfc2396E" href="http://purl.obolibrary.org/obo/ENVO_01000195"><http://purl.obolibrary.org/obo/ENVO_01000195></a>. That would be unambiguous.
However, if dwc:biome is reserved for literal values (as the RDF guide
suggests it should be) then how does a machine know that "flooded grassland
biome" is a label from ENVO and not a literal description of a biome from
the Whittaker, Walter, Bailey, etc. systems which are probably currently in
much wider use than ENVO and therefore likely controlled vocabularies of
choice for many users?

A machine will have no way to know from which vocabulary a value for a
property comes unless the value says so. That is common to all terms
that recommend a controlled vocabulary, but do not enforce it. It
would be no different for dwc:biome. The only way to be unambiguous is
to provide an unambiguous value, which, as you noted,
<a class="moz-txt-link-freetext" href="http://purl.obolibrary.org/obo/ENVO_01000195">http://purl.obolibrary.org/obo/ENVO_01000195</a> is.
