Daniel HernándezThis is Koblenz Hbf, the main train station in #Koblenz, #Germany. I am waiting for the train to Stuttgart. This is the third time @Ayenkantun and I visited Koblenz. This time we traveled to attend Philipp Seifer's PhD defense. I co-author several papers with him about #SPARQL #KnowledgeGraphs #SHACL #SemanticWeb He did a great defense! I am very happy!

"If there’s one insight we all need to focus on most, it’s this: your job is no longer to build a destination. It’s to build a parts library. And one that’s well documented so that when an AI agent re-assembles those parts for the human on the other side, the parts are put together in a way you wish to be represented.
The web has always evolved in ways that reduced brand control over the user journey. Ads replaced organic rankings. Featured snippets replaced clicks. AI Overviews replaced visits. This patent is the logical next step in that progression. The question isn’t how to stop this from happening, it’s how to make sure your parts are the ones AI wants to work with."
In short, this sounds like part of what the Semantic Web & Linked Data vision was about, also heavily based on autonomous software agents crawling, querying, extracting & re-assembling information on demand for a user. But the issue here is the plan to take Google's hyper-centralized and ubiquitous rent-seeking to whole new levels, pushing for the replacement of entire websites with essentially just machine readable repos of data/asset descriptors and then generating filtered/personalized/optimized websites on the fly, obviously for a more or less mandatory fee (not partaking likely ends up in invisibility)...
It's component-driven and reactive design taken to its ice cold logical conclusion... Queue a whole new set of "industry standards" (agreements between the main AI companies), frameworks, breathless consultants and an economy for "agentic arbitration", "agentic SEO", heck even "agentic premium themes" etc. arising around this... An army of human and machine middlemen all just to mediate the biggest middleman of all! It's the on-demand, ephemeral realtime web we've always dreamed of!
Zero permanence.
Zero record/archive.
Zero accountability.
Zero shared reality.
Zero leverage.
(Ps. After 15+ years, maybe even https://schema.org will have its time of glory on the horizon as part of this all...)
Marcel Otto🔹 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.
