  <pre wrap="">Steve,

I don't know which URLs you're specifically referring to and what you're doing to resolve them, but the ENVO term URIs work perfectly fine for me.

For example, the following curl command returns an OWL document with the term's class definition:

curl -L -H "Accept: application/rdf+xml" <a class="moz-txt-link-freetext" href="http://purl.obolibrary.org/obo/ENVO_00002036">http://purl.obolibrary.org/obo/ENVO_00002036</a> 

If you paste <a class="moz-txt-link-freetext" href="http://purl.obolibrary.org/obo/ENVO_00002036">http://purl.obolibrary.org/obo/ENVO_00002036</a> into your browser's address bar, it gets resolved to an HTML page showing the class, its properties, and its axioms within the ENVO ontology in a form meant for human consumption.

As per the OBO ID convention [1], the ontology in OWL format is available from the following URL: <a class="moz-txt-link-freetext" href="http://purl.obolibrary.org/obo/envo.owl">http://purl.obolibrary.org/obo/envo.owl</a>

    <pre wrap="">I attempted to dereference the URIs below as RDF/XML to see how the

to another (I think about 4 or 5 times).  Finally I got to a URI with a 
response  that said "Ontology not specified or not supported".  Can 
somebody post a link to some document somewhere that shows how the ENVO 
terms are defined in the RDF of the ontology?  Plus, somebody should fix 
the dereferencing so that a client requesting an RDF/XML representation 
gets a 303 redirect to an RDF file that defines the terms.

GBIF has just published "Meeting Report: GBIF hackathon-workshop on
Darwin Core and sample data (22-24 May 2013)" at
<a class="moz-txt-link-freetext" href="http://www.gbif.org/orc/?doc_id=5424">http://www.gbif.org/orc/?doc_id=5424</a>. Now that this document is

during the workshop and defined in the referenced document.

The formal proposal would change the term habitat to align it with the
ENVO habitat term. The related issues in the Darwin Core issue tracker

Label: Biome
Definition: A major class of ecologically similar communities of
plants, animals, and other organisms. Biomes are defined based on
factors such as plant structures (such as trees, shrubs, and grasses),
leaf types (such as broadleaf and needleleaf), plant spacing (forest,
woodland, savanna), and other factors like climate. Unlike ecozones,
biomes are not defined by genetic, taxonomic, or historical
similarities. Biomes are often identified with particular patterns of
ecological succession and climax vegetation.
