Semantic technologies permit powerful connections across #linkedData resources on the web. Until recently, developers had to learn the #RDF language to discover and use these resources.
Leveraging the new Model Context Protocol and LLM-powered natural-language interfaces, @Emekaokoye has created the RDF Explorer, an #MCP service that lets any developer surf the semantic web without having to learn its specialized language.

Actually, this is WIkipedia and only structured data, i.e. no RDF.
However, use this SPARQL query on DBpedia to get vitamins and minerals of a cucumber ;-)
#sparql #rdf #dbpedia #wikidata #cucumber #dbpedia @dbpedia #semanticweb #knowledgegraphs
that is rdf, isn't it?
does anybody know a sparql query to fetch that information?
Are there any open resources on food, food categories, ingredients

Hey @doriantaylor, I have some more dumb semantic web questions.
1. If I *don't* want to use a full existing ontology, because I intentionally want to have a simpler model during early phases of a project, is there a .. I guess a "sanctioned way" to enhance my ontology as time goes on without losing fidelity?
I know OWL's SameAs can identify individual resources as the same as some other resource, but this would kind of be that, only at the ontological level, maybe.
are there some #ipld guys in my bubble ?
We’re thrilled to announce pyjelly 0.4.0, the newest release of our #Python library for efficient #RDF knowledge graph serialization, using the Jelly protocol.
What pyjelly gives you:
Python implementation of the Jelly protocol, compatible with Jena and RDF4J.
️ Support for Jelly in #rdflib. An easy-to-use API for handling #KG serialization.
Our work on pyjelly is financed from the #EUFunds #EuropeanFunds.
Project value: 149 941,44 PLN

Today, I had the great pleasure of giving an introductory lecture on knowledge graphs at the #BILAI Summer School 2025 in Klagenfurt. Great energy and engagement!

Merci à tous pour vos présentations !
Nous avons reçu cette année 17 propositions pour SemWeb.pro 2025 !
Retrouvons-nous le 15 juillet pour découvrir le programme de cette édition.

Tomorrow, we will dive deeper into ontologies with OWL, the Web Ontology Language. However, I'm doing OWL-lectures now for almost 20 years - and OWL as well as the lecture haven't changed much. So, I'm afraid I'm going to surprise/dissapoint the students tomorrow, when I will switch off the presentation and start improvising a random OWL ontology with them on the blackboard ;-)

#SPARQL (SPARQL Protocol and RDF Query Language) est un langage conçu pour interroger et manipuler des données au format #RDF (Resource Description Framework), un modèle utilisé pour représenter des données sous forme de graphe, élément clé du Web sémantique. Toutes les données de Wikidata peuvent ainsi être décrites comme un triplet : sujet – prédicat – objet.
Cet atelier propose une initiation à SPARQL et au Wikidata Query Service.
#LibreABC2025
Thomas Kerboul, de la Bibliothèque de Genève, animera un atelier lors de la journée #LibreABC2025 sur les jeux de données dans #Wikidata.
#SPARQL #RDF
Description:
Wikidata est une base de connaissances libre et ouverte offrant un accès à des données structurées. Au-delà de la consultation élément par élément, Wikidata permet de visualiser une grande quantité de données sous forme de tableaux, de cartes ou encore de chronologies et de créer ses propres jeux de données grâce au langage SPARQL.
In this blog post at https://s.gwdg.de/m5Bu3L I showcase the #NFDI4BIOIMAGE (@nfdi4bioimage@nfdi.social, @nfdi4bioimage@bird.makeup) #knowledgegraph and its function as a registry for public #OMERO image data repositories and their respective #SPARQL endpoints. Annotated #bioimage data has become part of the #semanticweb. @joshmoore @Andrawaag #nfdi #metadata #KnowledgeGraphs #ontop #r2rml #rdf
OK @doriantaylor (or anybody), one more beginner question. When does a reasoner actually do its work? So, I've got a pile of data in whatever form, and I formulate a query. Then .... what? The reasoner looks at the datatypes in the query and says e.g. "if you're asking for publications that also means books or articles?" Or does it create dummy nodes for the existing data, so there's a publication node for every book and every article?

Back in the lecture hall again after two exciting weeks of #ESWC2025 and #ISWS2025. This morning, we introduced our students to RDF, RDFS, RDF Inferencing, and RDF Reification.

I just released version 0.1.0 of #Trinja, the #RDF-based static site generator and RDFS-to-HTML-renderer:
https://codeberg.org/Taganak/trinja
It can build working static websites from #LinkedData on a graph (in a somewhat limited fashion for the moment).
The README shows what it is supposed to do. I promise it will become more usefull in the medium run ;).
#TIL Netflix is actually using #RDF for their Unified Data Architecture
