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)

#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:

If you are at #39c3 and want to learn more about the current advances we made in the SDK of @nextgraph thanks to the contributions of @laurin ., he will be presenting his work on Tuesday the 30th at 10:30 in the CDC Triangle.

Yesterday I got some work done with Django AP Toolkit, finally solved one of the things that was bothering me in the mismatch between graph-oriented and object/relational-oriented programming: https://activitypub.mushroomlabs.com/topics/reference_context_architecture/#reference-based-relationships
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.
https://blogs.uoregon.edu/digitallibraryservices/2025/12/22/od2-rdf-02/
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

RDF/CBOR (https://openengiadina.codeberg.page/rdf-cbor/): Yet another RDF serialization.
But it has some new tricks:
- Optimized for small pieces of content (e.g. ActivityStreams objects)
- Allows content-addressing
It's designed for decentralized systems, passing around small pieces of RDF.
