Hi Rupert,

I see here two solutions:
(1) use a in-memory graph implementation (SimpleMGraph or IndexedMGraph): This
would be the preferred way in case such graphs are guaranteed to be reasonable
in size
(2) create a single graph and reuse it for all loaded Ontologies: This would be
the preferred way if such graphs are just a temporary cache but there could be
situations where they can get to big for holding them in memory
Again it's a matter of what should stay and what should leave, but
that's the Refactor engine's call (if it's that engine doing it).
The graphs used by Stanbol Rules should be about the same order of
magnitude as the enhancement graph, so I guess (1) could be ok for those.
If the recipes belong to the engine configuration, they should stay as
(2), and so should any metamodel. but I would recommend at least one
graph for each engine configuration.
Best,
Alessandro

Dears,
As I ran into disk issues, I found that this folder:
sling/felix/bundleXXX/data/tdb-data/mgraph
where XX is the bundle of:
Clerezza - SCB Jena TDB Storage Provider
org.apache.clerezza.rdf.jena.tdb.storage
took almost 70 gbytes of disk space (then the disk space has been
exhausted).
These are some of the files I found inside:
193M ./ontonet%3A%3Ainputstream%3Aontology889
193M ./ontonet%3A%3Ainputstream%3Aontology1041
193M ./ontonet%3A%3Ainputstream%3Aontology395
193M ./ontonet%3A%3Ainputstream%3Aontology363
193M ./ontonet%3A%3Ainputstream%3Aontology661
193M ./ontonet%3A%3Ainputstream%3Aontology786
193M ./ontonet%3A%3Ainputstream%3Aontology608
193M ./ontonet%3A%3Ainputstream%3Aontology213
193M ./ontonet%3A%3Ainputstream%3Aontology188
193M ./ontonet%3A%3Ainputstream%3Aontology602
Any clues?
Thanks,
David Riccitelli
