#rdf

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 ;-)

that is rdf, isn't it?

does anybody know a sparql query to fetch that information?

MAJOR RELEASE ALERT
Today we are launching BESSER v.4, with some massive improvements :
Project management: create new #modeling projects comprising different types of diagrams (#classdiagram, #statemachine, #objectdiagram...) in our #online #modeling #editor
Create object diagrams to model specific scenarios conforming to your class diagram
#Evaluate #ocl constraints on your object diagram and get #feedback on whether your scenarios are #valid
Plus many other improvements: #fluentapi, #rdf generation,...

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.

Aaaah, @gkellogg's new tests crashed my #RDF #Turtle parser, pointing me directly to a FIXME note from my past self …

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!

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.

As Heiko Paulheim is referring in his tutorial at ISWS 2025, his presentation on RDF2vec is not an individual contribution, but an effort of a great team of PhDs, PostDocs & students from his research group at University of Mannheim.

While working on a graph partitioning strategy, I stumbled upon an interesting paper
https://jbiomedsem.biomedcentral.com/articles/10.1186/s13326-024-00310-5
So, let me ask, what successful strategies for multi-level partitioning with #RDF named graphs have you applied or know about?
(beyond this paper and what it cites)

Notre prochaine intervention à #LibreABC le 9 septembre prochain s'intitule "Comment gérer ses fonds d’archives sous forme de données liées au moyen de la plateforme libre ResearchSpace"

Cela sera l'occasion de promouvoir l'utilisation de #RDF natif pour gérer des collections et de plaider pour une mutualisation des coûts de développement dans ce domaine.
