Hi,
can you give an example what you're trying to achieve? And what is the
use case? Query optimization? Text to SPARQL? Are you talking about
SPARQL, SHeX or SHACL?
In case of SPARQL queries, decomposing a SPARQL query into some
sub-structures depends on what you assume being parts for your use case.
Also, I'm not sure what you consider as [Start|Path|Sink]-Patterns? Are
those common terms?

Hi,
Using Apache Jena, decomposing a SPARQL query into sub-queries based on its
shape is what I need.
Indeed, you can see a SPARQL query as a graph - some people talk about
query graphs - and then you could apply common graph-based techniques to
divide the graph into parts. Traversing the SPARQL structure can be done
on the "Element" layer in Jena code.
But I personally, would simply convert the SPARQL query (or maybe the
algebra) to some JGraphT graph and then work on the method from this
graph-driven framework. At least that's how we were doing it in the
past. Indeed, this is mostly
So far, I found a class for StartPattern and I am
wondering if someone can tell me about such a resource for "path
pattern" and "Sink pattern" ... Thanks in advance
I don't see a class StartPattern in the code, that's only something in
the context of SHeX.
Best,
