In my techpresentations.org wiki, I have conference page like "OSCON 2006" that have [[Series::OSCON]] relations to the conference series pages.
Is there any way for me to select all objects of "Series" relation,
e.g. "OSCON" without selecting subjects of those relations. I also need to have them unique (similar to DISTINCT in SQL).
This can be easily done using regular RDF tools like Redland for example.
I can't find solution myself - any help will be appreciated!
