RDF Archiving SPARQL Experiments 2023

Repository containing code to run full SPARQL experiments with OSTRICH and Comunica.

Experiment data structure

The way the experiment code and corresponding docker has been setup expect a specific folder structure.
The experiment folder contains the following:

• "data.ostrich/" : OSTRICH files. Creation of those file should be done beforehand. (see the OSTRICH repository).
• "queries.json" : The file containing the queries.
• "progress.txt" (optional) : A file saving the progress of the experiments. The experiments will start from that point if the file exists.

Queries

Queries should be formatted as a JSON file and available in a subdirectory in your experiment folder.
Example queries, from the BEAR-C benchmark can be found in the "./queries" folder.

Run docker

docker build -t sparql-exp .
docker run --name sparql-exp --rm --volume path_to_ostrich:/var/ostrich sparql-archiving-exp
docker logs -f sparql-exp | tee output.txt

Alternatively, a script, "run-docker.sh" simplify the starting process of docker.
