Re: How to list OntModel Individual OntProperty triples?
Hi Steve!
Looks like you're looking for something similar to
Individual::getOntClasses, but I think there is no such method in the code.
Also, once getting statements, the type itself would be opaque.
What you can do is to call .canAs() and then .as() methods, for example
OntModel m = ...
ExtendedIterator<Individual> individuals = m.listIndividuals();
individuals.forEach(i -> {
i.listProperties().forEach(stmt -> {
Property predicate = stmt.getPredicate();
if (predicate.canAs(OntProperty.class)) {
OntProperty property = predicate.as(OntProperty.class);
}
});
});
But I think this is not what you want, but I can't think of why you
would need this?
Cheers,
Lorenz

They are, and inside a transaction.
What's the storage?

Atomic sparql Insert
Posted by ja...@kolumbus.fi.
Hello, I've about 10 000 variables in my Jena Fuseki v. 3.7.0 database.
All of them created using the INSERT DATA-command below.
I just noticed that four of those ~10 000 entries are missing the third
triplet:
gsimsf:EnumeratedValueDomain\/$TECH_NAME a
gsimsf_ont:EnumeratedValueDomain ;
gsimsf:hasStatId "$STAT_ID"
.
I've been considering INSERT commands as atomic, but now it looks like
some of them had been disturbed, can it be possible ? And if yes, how
can this be fixed ?
$PREFIXS
INSERT DATA
{ GRAPH tilasto:$STAT

gsimsf:Variable\/$TECH_NAME .

Re: How to list OntModel Individual OntProperty triples?
Posted by Steve Vestal <st...@galois.com>.
Thanks again, that worked to fetch statement predicates as both
OntResource and OntProperty.
This came up while experimenting to better understand rdf-frames (see
earlier apologetically lengthy Question about RDF Frames). However, this
might be useful when using SPARQL with OntModels and dealing with
imports that do not fully conform to OWL (e.g., use vanilla
rdf:property, which I have seen happen in files that have owl:Ontology
declarations).
