iiinova — where your digital self keeps evolving

Seeing the quality differences in AI output from high-tier AI and low-tier AI, I wonder whether a course that allows students to use AI can provide the same learning experience to everyone. How do we make this fair in a university setting?

I just published a paper with @patrickhochstenbach.net about building rule engines in the age of AI. I see this as a cornerstone for #Trustflows: interoperable, trustworthy data flows need rule engines that evaluate policies locally and consistently ↓ pietercolpaert.be/papers/seman...

Jelly-RDF allows to encode RDF Messages in a binary protobuf format. I was always sceptical whether that could really make a difference in the JS world, as I found parsing N-Quads was already quite fast and compresses nicely, yet... It turns out I was wrong. Repo: github.com/pietercolpae...

Jelly-RDF in JS is much faster to parse than TriG

This Friday from 10-13 is our opening lecture for Big Data Technology at Campus Ardoyen in Ghent. I invited an alumnus from my team now working at Lighthouse, and I invited the SNCB. It’s not a public event, but in case you'd like to join, drop me a note!

So, @anneschuth.nl called Linked Data harmful. Luckily we both prefer building over arguing, so I wrote a rebuttal with a future-oriented architecture and working prototype. The challenge: build the same data-integration pipeline without RDF. Your move, Anne. 😉 pietercolpaert.be/linkeddata/2...

Why on earth would you publish data as RDF? – Pieter Colpaert

A rebuttal to a blog post of Anne Schuth, I which I argue that RDF will earn its place in real neurosymbolic systems. Its best argument is eventual interoperability across organizations.

Standardization isn’t something you can just throw effort at and expect it to deliver. I often compare it to writing a hit song: being good helps, having a great marketing strategy helps, timing helps, having some funding helps, and so on.

There’s a tension between being semantically rich, and being semantically aligned. Eventual #interoperability is a new term I propose to indicate that you can do one after the other pietercolpaert.be/interoperabi...

Reusable specifications stack: project goals → interaction patterns → shapes → vocabularies → alignments.

The burden of aligning data has always been on the integrator. Linked Data is not about shifting this burden to the data producers entirely, but about distributing the burden equally in the ecosystem.

I am also gradually coming round to the view that interaction between humans/client apps and (perhaps multiple) AI agents is a state synchronisation problem that probably needs CRDTs lucumr.pocoo.org/2025/11/22/l...

LLM APIs are a Synchronization Problem

Maybe the LLM message APIs should be rethought as a synchronization problem.

Named graphs in #RDF (2014) are still controversial after all this time and I don’t think they should be. While their semantics were left open, functionally we all use them as contextual assertions anyway. Prove me wrong 🤓 👉 pietercolpaert.be/linkeddata/2... #linkeddata #knowledgegraphs
