[Eulergui-user] New TDB cache in Semantic Web Explorer

[Jean-Marc V. <jea...@gm...>]

Jena TDB is a native Semantic Web database from Apache Foundation.

The TDB cache is implemented in class RuleBasedApplicationWithCache.
It reuses both triple store in memory (Drools backed rule engine), and
persistent TDB store.

Its is used in the new Semantic Web Explorer application,  and as an
EulerGUI editor menu Action ; and is also useable as component.
The SW Explorer has now a second CL argument for adding Knowledge and
rules from an EG project.

Soon EulerGUI will use the new cache, so that SPARQL queries will be
possible on the whole set of URI's downloaded from the first use of
EG.
Note that there is already a cache in EulerGUI, based on opensymphony
OSCache. So already now, there is no need to re-download things from
internet, except if the timestamp shows a new version. This
OSCache will probably continue to be used for comiled Drools rule bases.

There is a snapshot at the usual place:
