Hi Aarthi
I don't know whether it will solve your problem or not, but since you
mentioned ontology mapping, maybe you would like to know the Align API (

Not sure how your data is arranged on MySQL, but have a look on D2R (

The better plan for the query you posted would be (1), simply because of

Hi all,
I'm having trouble figuring out how Transformer class is working. See my
classes below:
public class GrumpyOptimizer extends TransformCopy {
@Override
public Op transform(OpUnion opUnion, Op left, Op right) {
if ( !( left instanceof OpService right instanceof OpService))
return
. In
public Op transform(OpUnion opUnion, Op left, Op right)
opUnion is the original input, and left/right the new sub ops due to the
transforming the elements below this union, so you can see both original
and sub-writes.

Hi Milorad
According to the sparql reference, multiple FROM clauses should mean a
query over the merge of all specified datasets, so the expected results you
presented should be returned indeed. Is this a bug?

Hi
Please forgive any mistakes below.
SPARQL is a language to deal with data; OWL is meant to deal with concepts.
You may argue that both can produce the same results. However there is an
important difference: the language.
As using owl one may represent both concepts and their relations in
