The web-service branch of BioMOBY is up and running happily (and is
being well-used!) but is somewhat locked-in to a legacy XML format that
was designed a couple of years before RDF became "the norm".  This is
unfortunate, since the MOBY XML format was designed to do a very similar
job - that is, serialize an ontology.  

Nevertheless, we are muddling through, and though the messages that are
being passed between service and client are in this MOBYesque XML
format, we do use ontological queries to achieve the "semantic mapping"
between a client with a piece of data, and the various services that
could operate on that data.  The guts of MOBY are very rapidly being
migrated to use OWL/RDF to enhance and simplify this semantic mapping
using a reasoner, but the messaging format will remain a legacy problem
for quite a while since we have so many services that use it now...  It
seems, however, that we can inter-convert our XML with RDF fairly easily
and reliably, so this may not be as big a problem as we had initially
thought.

Eric Miller (on this list) has seen my presentation of MOBY and talked
to me briefly about it, so he may have some comments on how close/far we
are from a "true" semantic-web-service vision... given that we built
this in 2001, I think we got it ALMOST right! ...personal bias, of
course ;-)

"For most of this century we have viewed communications as a conduit, 
       a pipe between physical locations on the planet. 
What's happened now is that the conduit has become so big and interesting 
      that communication has become more than a conduit, 
       it has become a destination in its own right..."
