Hi All,

I'd like to announce the availability of overdogg.com (beta), a marketplace
for matching user/group needs with providers and sellers.

overdogg.com uses the Things You Want and Need
(TIWAN)<http://overdogg.com/ontology/tiwan>vocabulary to allow users
to use links/URLs to point to the things and
services they want. Just take the URL link of a
user<http://overdogg.com/rdf/members/bullit323>(which is displayed on
the request) or a
request <http://overdogg.com/rdf/requests/716> (use the URL, or go to the
request homepage, scroll down and find the rdf link on the left side panel
to get the URI) and put it in an rdf
brower<http://demo.openlinksw.com/DAV/JS/rdfbrowser/index.html>.
We feel that using links to describe needs (to supplement simple raw text,
folksonomy, etc) improves search and retrieval of ads by qualified providers
and human match makers, as well as assists automated matching services. This
also is inline with linked data principles (i.e. a query can now be made
which says *all people in city-x who want a product-y which is has been
rated or tagged NEGATIVE by more than three people*, where the ratings info
can come from sources like Yelp.com and de.lico.us). Many more examples can
be made, but the power of linked data sets lies in what the publisher can
not predict :)

The service provides features for importing and exporting RDF (TIWAN and
FOAF) descriptions, as well as manging solicitations to requests, portable
reputation (courtesy of rapleaf.com), and building a friends network of
trusted service providers.

The service is currently crawling the wanted section of craigslist.org in
various cities. There are about 50K listings for the time covered by the
current crawl, with about 5K or so being added every few days. The
pingthesemanticweb service is pinged each time a user profile or new request
is added to the system, so you should be able to pull a bulk dump from
there. We plan to add data from Myspace and Facebook want ads soon.

I encourage you to check out the service and please share your comments and
suggestions. Keep in mind that the service is BETA in every sense of the
term, if you hit an error page, try hitting the refresh button.

Enjoy,
-sherman
