Hi Dhaval,
this is a "feature", not a bug - the statements (including the inferred ones)
that come from the files listed in the "imports" parameter of your repository
configuration are treated as "read-only" thus, these are "protected" from
delete operations - just do not put any data that would be deleted through that
parameter ...
about the missing update/modify statement operations - there is no such since
changing any of the triple components (subject, predicate or object) means,
actually, that the old triple is removed and a new one is asserted instead ...

Subject: [Owlim-discussion] delete operation in owlim
Dear list users,
I have been trying to remove (delete) some statements from an ontology
(schema) with big-owlim using following code :
OwlimSchemaRepository myOwlim = new OwlimSchemaRepository();
myOwlim.setDataDir(repoDir);
Repository sesameRepo = new SailRepository(myOwlim);
sesameRepo.initialize();
RepositoryConnection sesameCon = sesameRepo.getConnection();
Resource S1 = new URIImpl("subject of statement");
URI P1= new URIImpl("predicate of statement");
Value O1 = new URIImpl("object of statement");
sesameCon.remove(S1, P1,O1);
sesameCon.commit();
The above doesn't work, i.e. the deleted statements are still present when
queried. However, the same code and settings work while deleting
A-box/instances. Any suggestions?
Also, on another matter I could not find any code/listings in sesame/bigowlim
that can allow me to modify/update a statement, any hints?
Regards
Dhaval Thakker
