Last week I attended ISWC 2014 in Riva del Garda and had a very nice time. I presented a paper at the Developers Workshop about designing the new PerlRDF and SPARQLKit systems using trait-based programming . Covering more PerlRDF work, Kjetil presented his work on RDF::LinkedData . Answering SPARQL Queries over Databases under OWL 2 QL Entailment Regime by Kontchakov, et al. caught my attention during the main conference. The authors show a technique to map query answering under OWL QL entailment to pure SPARQL 1.1 queries under simple entailment, allowing OWL QL reasoning to be used with SPARQL 1.1 ...
