Hi,

I have created 4store storage and query modules for librdf as a part of the work done toward my Masters in Computer Engineering. The implementation can successfully perform the same operations as the tests for the Virtuoso module*. The code that I have produced itself is a bit hacky and still needs some work to be really useful. I am now trying the measure the implementation that I have done with the other storage options in librdf.

My question is two-fold:

Is there any interest in the Redland-dev community to complete the work I have done in integrating 4store as an storage module in librdf, as I lack both the time and real motivation to complete it myself?

When trying to benchmark the BDB storage using data produced using the LUBM** data generator and evaluating the test queries listed in the benchmark, I am unable to produce any result as the system stalls. With my 4store storage implementation I get the results just fine. Is the BDB storage solution unable the process the queries on datasets of 100K triples or have i messed up somehow?
