Jena 2.6.3 has been released - this is primarily a maintenance release.

This is also the first release of Jena since many of the contributors
left HP and we hope this shows that we remain committed to Jena as an
open source project.

The download is on SourceForge and the Maven artifacts are mirrored to
the central Maven repository.

Release Notes
=============

GraphBase:
o Added limits to the number of triples thatr GraphBase.toString() will
serialise.

Model/Resource API:
o Took advantage of covariant return types to allow
Resource.inModel() and
Property.inModel() to have Resource resp. Property return types,
allowing
casts of calls to inModel() to (mostly) be eliminated.

o As per request on mailing list, ModelGraphInterface now has a method
`Resource wrapAsResource(Node)` [name changed to fit better] which
wraps a node as a Resource and throws if the node is a Literal.

o As per request on mailing list, added Resource method
x.getPropertyResourceValue( Property p )
which answers some R such that x p R if any exists, otherwise null

o As per request on mailing list, there's now an OWL2 vocabulary class
with constants for the terms of OWL2. NOTE: there is no OWL2 ontology
support present or implied by this vocabulary class.

o getModel() has been pulled up from Resource to RDFNode. This
means that
Literal now supports getModel() and inModel().

o RDFNode has .asLiteral() and .asResource() methods, which deliver
the Literal or Resource respectively if the RDF Node has that type,
and otherwise throw a *RequiredException.

Misc:
o Patched AnonId using UID when running in environments like GAE
o Fixed problem with comparison on XSDDurations with fractional seconds

Reasoners:
o added makeSkolem builtin
o fixed deadlock problem with hybrid rule systems
o changed interpretation of Functors so they are neither literals
nor objects,
this allows validation of nested reasoners to cope with the
introduction of
functors representing inferred individuals
o improved RETE initialization so that fewer triples are injected
into the rule network in cases such as the RDFS no-resource rules

Ontology API:
o Fixed NPE bug when an ObjectProperty was not the inverseOf another
property

Schemagen:
o Internal refactoring, which should not affect the external
behaviour but should
make it easier to extend the schemagen class
o Individuals in an included namespace now appear in the output,
even if their
rdf:type is not included.
