Hi all,
I'd like to hear from you the "optimal/suggested" way to rename a named
model into TDB dataset on file system.
Does adding the same Model twice in two different named models, duplicate
the triples or it does some "symlink"?
Duplicate.
TDB stores quads g-s-p-o (and triples for the default graph).
If you want a different "g" its needs to copy the quads.
It's dictionaried - each using of the same RDF term is the same internal
id so the copy is of the quads, not the RDF terms themselves.
I've to load a very huge ontology (TDB size is 5.5GB after its load)
Not that large :-)
from
file into a named model, in my TDB dataset on file system, which will be
named as this ontology owl:versionInfo/versionIRI (if present).
At the moment, to do that I load the ontology into a temporary TDB dataset
on file system, then I read owl:version* from that model and I put the
ontology in a named model in my main dataset.
I don't put it directly into my main dataset just to avoid to lock it
during the owl:version* check.
You could do a streaming pass over the data to find the required naing
info them load.
Thanks.
Cheers
