Assuming that the conference "Perspectives on Scientific Error" 2026 (also known as PSE8)
https://perspectivesonscientificerror2026.wordpress.com/
has the #hashtag #PSE8, I am happy to report that it now also has a presence in the #nanopublications ecosystem at https://w3id.org/spaces/PSE8
In preperation for the nanopublications hackathon om 2026-02-13, we are going to use that space to experiment with the use of nanopublications for conference microblogging.

from the linked GitHub issue: "Here is a demo of QLever handling one trillion triples on a single commodity PC: https://qlever.dev/one-trillion . That is more than fifty times larger than the current Wikidata" #sparql #rdf #opensource

Hi lazywell,

is there a standard CLI tool that can be used to extract all the descendants (rdf:subClass ? ) of a given term from a local OWL ontology file ?

I wrote a stupid java xml tool but I'd like a tool that understands the OWL spec (I don't)

#rdf #ontology #owl #bioinformatics

#OpenScience and the #fediverse .. let's get that ball rolling 💪

@jfietkau @jonny and @bonfire opened a brainstorm and evaluation on how we can provide better support for the academic world and #science in general to the #ActivityPub-based fediverse.

Various different iniitiatives are underway, and there's great opportunity to bundle forces and align these efforts where possible. Set standards.

Interested? Join the discussion:

And today I think I got closer to solve another part that was bugging me: most #ActivityPub sofrware does not deal with #RDF and instead relies on the JSON coming with a specific shape. THis means that even RDF-aware servers need to be able to select what data to put in a document. After iterating on some designs, I got something that seems acceptable by using "Projections": https://activitypub.mushroomlabs.com/topics/projections/

After a year since last time, I got back to playing with our digital-collections RDF exports and writing about it -- this time, aggregating some descriptions from id.loc and Wikidata. It was fun.

I believe we still have a fair bit of work and cleanup before we'd expose the data publicly. Maybe that's what I'll write about next year...

The @w3c SHACL 1.2 Rules specification is an addition to the Shapes Constraint Language (SHACL) family of documents. It provides a standardized way to express and evaluate declarative rules that generate new data (as #RDF triples) by inference on existing RDF data. #FPWD #timetogiveinput
