Soprano 2.4.0 released

Soprano has seen some nice work since the 2.3 release series. And just in time for KDE SC 4.4.0 I present the next step in Qt RDF data handling: Soprano 2.4.0.

  • New methods Client::SparqlModel::listStatementsAsync and Client::SparqlModel::listContextsAsync.
  • Automatic query prefix expansion in NRLModel.
  • Automatic NRL metadata graph removal in NRLModel.
  • ServerCore is now fully multithreaded allowing two clients perform read-only commands simultaneously.
  • New Virtuoso storage backend which can either connect to a running Virtuoso instance or spawn one locally.
  • New convenience methods to handle BackendSettings.
  • New class AsyncQuery which will spawn a new thread for real asnycroneous query execution (in contrast to AsyncModel which only performs the actual query call in another thread while the iteration is syncroneous).
  • Removed redland/librdf dependancy from raptor parser.
  • Sopranocmd improvements:
    • New paramter --nrl for sopranocmd which will trigger automatic query prefix expansion based on prefixes stored in the underlying model, automatic context creation for imported statements that do not have one set, and automatic metad ata graph removal on removeContext calls.
    • New parameter --graphselect which allows to convert SPARQL select query results into a graph result. This is very usable since SPARQL construct queries do not support contexts/named graphs.
    • New command 'rmgraph' which allows to delete a list of graphs/contexts.
    • New parameter --foo which enables scriptable binding results without variable names.
