DawgShows
The RDF developer community has been working on RDF Query for a while now... W3C even started a working group, DAWG, which has released a SPARQL query language spec and is talking about a SPARQL Protocol spec.
SparqlImplementations lists some implementations of the query language and protocol.
The following are some DAWG Shows, i.e. demo services you can play with, or events where SPARQL will be presented, that sort of thing.
Demo services and applications:
- ISWC2006 Semantic Tools includes a SPARQL endpoint
- GovTrack.us SPARQL form by Joshua Tauberer with about 10 million triples
- Schemarama 2 Test Framework and Service, from 12 Dec 2005 announcement: uses SPARQL for quality assurance and integrity testing of RDF data (a bit like 'validation'). See also specific test cases for the SKOS Core Vocabulary.
- Opera SPARQL Query Engine, from 30 Nov 2005 announcement: uses Redland/Rasqal to do the hard work, and gives you almost 2.7 million triples of my.opera.com data to play with.
- XMLArmyKnife -- SPARQL general purpose SPARQL service since announcement Nov 15, 2005 with several updates since
- SPARQLer - An RDF Query Demo by Andy Seaborne 5 Nov 2004

EricP, is your algae-based stuff public yet?
Are there some demos from the lifesci workshop? Maybe they're mostly RDQL... any that are migrating to SPARQL?
