Excited to connect with https://www.ioer.de/en/projects/switch – and curious to see if https://www.valueflo.ws/ and https://changinggraph.org could become a triple. 🤞

How to model temporal aspects and temporality in RDF, esp. in the domain of cultural heritage?
Our newly published paper "Temporal Modelling in Cultural Heritage Knowledge Graphs: Use Cases, Requirements, Evaluation, and Decision Support" by @sashabruns @joerg Jeff Pan and @lysander07 in Transactions on Graph Data and Knowledge will provide you some answers 🎉

J'adore écrire des articles à rallonge sur des trucs qui n'intéressent pas grand monde, donc voilà un article beaucoup trop long sur RDF, SPARQL, comment on self-host un serveur SPARQL pour faire des requêtes avec ses propres données (avec comme serveurs présentés Oxigraph, QLever et MillenniumDB), et comment on convertit des données d'OpenStreetMap pour faire des requêtes SPARQL avec.
Featuring beaucoup trop d'exemples parlant de trains.

Also if you are into #rdf and #knowledgegraph you have heard of tinker pop gremlin 👹 then the following pipeline might remind you some good souvenir:

´´´
(let ((g (make-graph gremlin-n gremlin-e 10 12345)))
(display "Graph: ")
(display gremlin-n)
(display " vertices, ")
(display gremlin-e)
(display " edges/vertex, 10 groups")
(newline)
(let ((tri (time
(traverse g
(V)
(as a)
(out)
(as b)
(where (same-group? g a b))
(out)
(as c)
(where (same-group? g a c))
(where (edge? g c a))
(count)))))
(display tri)
(display " triangles")
(newline)))

Have I ever mentioned that I think #triplestores, especially ones that use a #datalog query language. are absolutely brilliant? It’s strange that they aren’t more widely used. #clojure #RDF #edn #lisp #databases

Finally got around to rebuilding my personal website: https://naturzukunft.de

It explains what I'm working on: open, federated infrastructure so small initiatives — repair cafés, community gardens, food co-ops — become visible to AI systems. Not another platform. Open rails.

I’ve been thinking about graph databases and #RDF way too much recently 😅
🔹 RDF.ex 3.0 is out!
The headline feature: the new RDF.Data.Source protocol, following Elixir's Enumerable/Enum pattern for RDF data. Implement a small set of primitives, get a full API for iteration, transformation, navigation, and aggregation - across Descriptions, Graphs, Datasets, and custom implementations.
Plus various other improvements.
