[provenance-challenge] release of opm toolbox v1.1.1

[Luc Moreau]

I am pleased to announce the release of the OPM Toolbox 1.1.1. It
incorporates the recently proposed OWL ontology for OPM v1.1, and
conversion to/from RDF.  Minor changes have been incorporated to the
XML Schema to ensure bidirectional conversion between XML and RDF.

Key changes to the toolkit:

    * Better support for annotations
    * Elmo based serialisation/deserialisation to/from RDF
    * opmconvert converting between xml and rdf
    * Support for time
    * Introduction of exactlyAt as an abbreviation for
        noLaterThan and noEarlierThan with same value

All information on OPM v1.1, the schema, the ontology, and the OPM
Toolbox available from openprovenance.org.

Maven artifacts are available from
http://openprovenance.org/java/maven-releases/. Source code is
available from http://github.com/lucmoreau/OpenProvenanceModel.
