I have been heavily involved in the development of the W3C RDF and OWL languages, editing several of the foundational documents for both. If you have a question on how RDF or OWL works, feel free to ask me at pfpschneider@gmail.com

I was in the W3C Data Shapes Working Group, which was developing a constraint language for RDF. I am in the W3C RDF-star Working Group, which is adding quoted triples to RDF.

I am interested in improving the Wikidata ontology. I have been working with Ege Doğan on finding and fixing problems in the Wikidata ontology related to disjointness - https://arxiv.org/abs/2410.13707 - and class order - https://arxiv.org/abs/2411.15550.

I have been benchmarking SPARQL engines on Wikidata. See https://www.wikidata.org/wiki/Wikidata:Scaling_Wikidata/Benchmarking for more information on this effort. My most recent work in this area was developing larger versions of Wikidata for benchmarking, to show how the engines might slow down as Wikidata becomes larger.
