Thanks, Andy. We're trying to:
1. convert xsd:dateTime to timeInMsec
2. do some simple multiplication/division

Problem solved. The literals need to be constructed as something like

Unfortunately, we're using an older version of Jena (2.7.2) for compatibility
with the Oracle Jena adapter. I see more recent versions have these methods
on OntModel:
listClasses()
listDatatypeProperties()
and so on. How can I do the equivalent using Jena 2.7.2?

Hi -
Is there a way to check the consistency of triples with one's ontology prior to
insertion into the graph? If not, are there APIs to validate the existing
graph against one's ontology?
Thanks -
Found a good example here (#5):

You can see the Apache Jena SDB versions and check their versions by looking
I want to load triples into an empty SDB Store. Here's what I'm trying:
Store store = getStore();
GraphSDB graph = new GraphSDB(store);
DatasetGraph datasetGraph = DatasetGraphFactory.create(graph);
if (datasetGraph.isEmpty())
{
System.out.println(Empty dataset graph); // yes, it is
}
I have a graph that is referenced 'Event1' in my default graph, with object
properties w:userFollowed and w:occurred.This query works:
SELECT DISTINCT ?graph ?time WHERE { ?graph w:action w:userFollowed;
w:occurred ?time }
This query works as well (which is in the named graph, Event1):
Disregard -- this was a test data issue, not a SPARQL query issue.

I've been using TDB, but now want to set up a test environment with in-memory
graphs. Using TDB, I could create a Dataset to query as:
String directory = /scratch/tdb/demo1 ;
Dataset ds = TDBFactory.createDataset(directory) ;
Query query = QueryFactory.create(q) ;

How do I add a named graph to an in-memory Dataset? This code works with TDB,
but the in-memory implementation throws:

with the Dataset abstraction and only go to the
lower level DatasetGraph where necessary.
