SPARQL 1.0 for Ruby

I’ve just released version 0.0.2 of the Ruby sparql gem. This version is based on earlier work by Pius and Arto and incorporates from SPARQL Grammar and SPARQL Algebra. Further documentation is available here.

rdf.rb 0.3.4 released

After several months of gathering updates for RDF.rb, we’ve released version 0.3.4 with several new features:

RDF::RDFa update with vocabulary expansion, RDF collections and more

I’ve updated RDF::RDFa with updates from recent changes to RDF Core:

RDF::N3 no longer accepts text/turtle or :ttl

With the release of RDF::Turtle, starting with version 0.3.5, RDF::N3 no longer asserts that it is a reader for Turtle. This includes MIME Types text/turtle, application/turtle, application/x-turtle. Or the .ttl extension or :ttl or :turtle formats. Of course, N3 remains reasonably compatible with Turtle, but the recent RDF 1.1 Working Group publication of the Turtle Specification has caused some divergence.

Channel Islands July/August 2011

Recently returned from a 3-day trip on the Horizon out of San Diego. We had two great days at San Clemente Island, and spent the last day outside San Diego, with two dives on the Yukon, a former Canadian Destroyer sunk as an artificial reef and dive site. Unfortunately, it went down early and landed on It’s side; It’s now known as “Milt’s Tilt”. Enjoy the photos.
