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.

🔹 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.

🔹 Gno is an Elixir library for managing RDF datasets in SPARQL triple stores.
A unified API across Fuseki, Oxigraph, QLever, and GraphDB - with an extensible commit system featuring a middleware pipeline, transactional execution, and automatic rollback.
Ontogen's entire versioning logic is implemented as Gno commit middleware.

🔹 DCAT-R extends W3C DCAT 3 with an intra-service perspective for RDF repositories.
Where DCAT describes what a service looks like from outside, DCAT-R adds vocabulary for how an application organizes its RDF repository internally - graph types, distribution boundaries, directory structures, manifests.
It's designed as a framework for services like Ontogen.

🚀 New releases from the Ontogen and RDF on Elixir ecosystem 🧵
Two new projects and a major update to RDF.ex:
🔹 DCAT-R - a spec + vocabulary for describing RDF repositories 🔹 Gno - a library for managing RDF datasets in SPARQL stores 🔹 RDF.ex 3.0 - with a new protocol for polymorphic RDF data access
Details in the blog post: https://ontogen.io/blog/dcat-r-gno-and-rdf-ex-3
Thanks to @nlnet for making this work possible through the NGI Zero Core fund! 🙏

RE: https://w3c.social/@w3c/116216070362563670

FWIW, I have been storing Linked Data (including ActivityPub) in an INI like format — because I find INI-like formats more human-friendly (to both read and write) than JSON.

YAML is probably better than JSON, too, in that respects. But I think INI-like formats are better than YAML.

World Wide Web Consortium Mar 12

The JSON-LD Working Group published today a First Public Working Draft of YAML-LD 1.0. [JSON-LD11] is a JSON-based format to serialize Linked Data. In recent years, [YAML] has emerged as a more concise format to represent information that had previously been serialized as [JSON], including API specifications, data schemas, and Linked Data.

CBOR-LD 1.0

"CBOR is a compact binary data serialization and messaging format. This specification defines CBOR-LD 1.0, a CBOR-based format to serialize Linked Data. The encoding is designed to leverage the existing JSON-LD ecosystem, which is deployed on hundreds of millions of systems today, to provide a compact serialization format for those seeking efficient encoding schemes for Linked Data. By utilizing semantic compression schemes, compression ratios in excess of 60% better than generalized compressi..."

📢 HMC FAIR Friday Seminar

More than a decade after the FAIR Principles were introduced, a key question remains:

👉 What value has FAIR actually delivered to researchers?

In this talk, Sebastian Hellmann and Jan Forberg explore the microeconomics of FAIR adoption and present open-source tools #Databus and #MOSS from the #DBpedia Association ecosystem.
