"Retour sur la mise en oeuvre d'un modèle de données ouvert dans une institution patrimoniale"

Voici le thème que nous aurons le plaisir de présenter le 15 octobre 2025 lors la journée d'étude DaSCHCon à Berne (Suisse).

Les inscriptions sont ouvertes ! Les places limitées sur place mais la journée peut aussi être suivie à distance.

La présentation sera disponible en ligne après la journée.

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.

However, there is another way:
publishing a SPARQL endpoint for RDF data that conforms to commonly used ontologies and which is self documenting using VoID.

Here's a list of very common ontologies, so much so they are part of the RDFa Core Initial Context: w3.org/2011/rdfa-context/rdfa-
And here's a description of how to use VoID: w3.org/TR/void/

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.

Storing #RDF or #LinkedData is the easy part (I am working on #activitypub client, so everything is JSON-LD anyway), but as soon as I need to formulate queries like "Give me list of the activities from all the actors who are on the following collection of my user, sorted by published/updated date", the amount of data mangling that I need to do is already making me think "ok, why don't I just push all of this to sqlite?"

#couchdb experts (@janl, @nolan), any suggestions here?

🔗 SHACL-SKOS Based Knowledge Representation of Material Safety Data Sheet (SDS) for the Pharmaceutical Industry

arxiv.org/abs/2502.07944

arXiv.orgSHACL-SKOS Based Knowledge Representation of Material Safety Data Sheet (SDS) for the Pharmaceutical IndustryWe report the development of a knowledge representation and reasoning (KRR) system built on hybrid SHACL-SKOS ontologies for globally harmonized system (GHS) material Safety Data Sheets (SDS) to enhance chemical safety communication and regulatory compliance. SDS are comprehensive documents containing safety and handling information for chemical substances. Thus, they are an essential part of workplace safety and risk management. However, the vast number of Safety Data Sheets from multiple organizations, manufacturers, and suppliers that produce and distribute chemicals makes it challenging to centralize and access SDS documents through a single repository. To accomplish the underlying issues of data exchange related to chemical shipping and handling, we construct SDS related controlled vocabulary and conditions validated by SHACL, and knowledge systems of similar domains linked via SKOS. The resulting hybrid ontologies aim to provide standardized yet adaptable representations of SDS information, facilitating better data sharing, retrieval, and integration across various platforms. This paper outlines our SHACL-SKOS system architectural design and showcases our implementation for an industrial application streamlining the generation of a composite shipping cover sheet.

🎉 After a year of intense work, I'm pleased to introduce Ontogen - a version control system for RDF datasets. 🚀

It's been a challenging but rewarding journey, and I'm excited to share the results with the #rdf and #knowledgegraph community.

You can find more about Ontogen at ontogen.io
The website includes a user guide and the first two articles of an introductory series (more to come in the next few days).
The best place to start reading is ontogen.io/introduction/part-1

Java is an interesting language for a Fediverse project because it's the one language with several mature implementations of Semantic Web tech (RDF, SPARQL, etc). JSON-LD just works, out of the box. It was kind of shocking to see Apache Jena do in a few minutes of work what took me weeks in Deno!

And I learned about a piece of the Semantic Web ecosystem I wasn't familiar with before. Have you heard the good word of OWL?

ActivityPods

Hi Fediverse, a short #introduction !
ActivityPods is a general-purpose ActivityPub server that uses #SolidProject pods to store user data in a standardized, semantic, interoperable data format, #RDF.

This way, we bridge the gap between an interoperable web, where users are in control of their data, and the social web.
Developers can focus on creating client applications without having to worry about the backend for most parts.

Currently, we are working on version 2.0: activitypods.org/the-road-to-a

ActivityPodsThe road to ActivityPods 2.0Since this summer, thanks to a grant from NLnet as part of the NGI0 Entrust Fund program, we've been working hard on ActivityPods 2.0, with a planned release in spring 2024. The aim of this article is to explain this background work and what's at stake.
