Ontotext, the Bulgarian Semantic Web company of OWLIM fame, have given me the opportunity to return to working on Sesame as a developer. Specifically, I have been contracted to help implement SPARQL 1.1 Query and Update into the Sesame framework.
Work has already started and I'm happy to report that various features have already been implemented and tested - the fact that Sesame's query algebra is based on the SeRQL language helps a lot here, as various SPARQL 1.1 features were already available in SeRQL. This includes the use of expressions in the SELECT, as well as negation features and subqueries. More challenging will be the inclusion of aggregates and property paths. More soon.
