I just realized the following phenomenon regarding the efficiency of the "normal" pattern trick + I assume this also applies for the new code. Namely, consider the following query on...

Yes, and the problem is that the input stream is parsed in parallel, so that it can happen that a triple is parsed before the respective prefix definition has been...

Incidentally, which subfolders of https://ftp.ncbi.nlm.nih.gov/pubchem/RDF should we consider? I am currently considering (I left out `reaction` because it's empty): ```bioassay compound/general concept conserveddomain descriptor/compound descriptor/substance disease endpoint gene inchikey measuregroup...

@ external vocabulary: I can tell you more when my current build has finished. By default, all literals longer than 1024 bytes and all language literals (with an @.. suffix)...

@donpellegrino My index build is now finished and the respective QLever instance is online here: https://qlever.cs.uni-freiburg.de/pubchem . The index build took 20 hours and the number of triples is 14.2...

@donpellegrino Great reply, thanks! You say that you manually "collect all the OWL files [you] can find that are referenced by PubChem RDF". That makes a lot of sense. Can...

Here are a few comments concerning your question about how to build a QLever index when machine time is limited: 0. This is a rather unusual constraint. Have you considered...

It's trivial for anyone to generate that documentation theirselves: just checkout the code and run `doxygen`. I am not sure how useful that is though. The code is already on...

@dpriskorn Not really useful in my experience without an accompanying document explaining it. Especially not for a very large project with very many classes

@donpellegrino Thanks! We have not started working on "SPARQL 1.1 Update" yet, but are currently still busy with preparatory work leading up to it. You ask whether "existing SPARQL Federation...
