Hi David,
well, I guess that depends pretty much on how heavy the usage of OntoNet
is in your Stanbol installation.
Those are graphs created when OntoNet has to load an ontology from its
content rather than from a Web URI, so it cannot know the ontology ID
earlier.
This happens e.g. by POSTing the ontology as the payload or by passing a
GraphContentInputSource to the Java API.
Now I do not know why these graphs are created (perhaps the refactor
engine could be loading some), but I do know that a Clerezza graph in
Jena TDB occupies a LOT of disk space.
Suffice it to say that my bundled had stored nine graphs of <100 triples
each. Their disk space was about 1.8 GB, but when I tried to make a
zipfile out of it, it came out as about 2MB!

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
