bergis universe of software, hardware and ideas

Standards work is slow: mailing lists, issue threads, and meetings where a single property name can take three sessions.So the fair question is why I spend so much of my time on it instead of writing code people can use tomorrow.

The origin of most data in the world comes from closed-world systems.Forms, logging systems, and sensors all generate data in predefined structures where the schema is known in advance.Yet when people enter the world of RDF, interested only in adding sema…

OpenAI has recently introduced the Agentic Commerce Protocol (ACP), which enables shopping and purchasing directly within ChatGPT.That is a step forward for agentic applications.Still, it only scratches the surface of a much broader problem: How to safely…

The experimental branch of shacl-engine is now introducing features related to the upcoming SHACL 1.2 specifications, along with some proposals still under discussion.These additions are in an early stage of development, meaning they may be incomplete or…

Many blog articles and LinkedIn posts claim that Knowledge Graphs and Language Models are a good match and that potential future products that combine both worlds will be even more powerful.I work in that field because I strongly believe in that idea, but…

Knowledge Graphs combined with modern language models is still a hot topic.We have seen many demos in the past, and increasingly, they have become features in products, but most of the time, they are connected inefficiently.In this blog post, I will take a

I hoped the “Leaving the Sinking Zazuko Ship” blog post would be the last post about Zazuko, but then they stole my code.

While working on RDF/JS specifications, I fulfilled two roles.

After almost 9 years, I left Zazuko, the company I co-founded, for good at the end of June.Like I share my open-source libraries with you, I was hoping you could benefit from the lesson I learned about how a dark triad personality ruined a company.

Graph traversing with plain RDF/JS objects is no fun.

I guess it was not only my social media stream that was flooded with GPT4 news in the last few days.The results are impressive but not surprising to me.A combination of events, which are more important from my point of view, didn’t get that much attention:

This year, RDF-Ext will turn ten years old.In this blog post, I will give a brief overview of recent updates, show the current plans, and explain how you can help improve RDF-Ext.

One of my projects encountered a performance problem with the available SHACL engines.Besides, I needed to know which triples had been processed (coverage/fragments), so I implemented a new SHACL engine in JavaScript from scratch.

In my last blog post, I wrote about how to detect LLM output, with the conclusion that machine-learning approaches are not the solution.Today I want to show how the recent news “Man beats machine at Go in human victory over AI” is related to that topic.

Recently the question of whether and how text generated by large language models (LLM) can be distinguished from human text showed up in the W3C Semantic Web mailing list.A solution that seems obvious at first glance would be to use the same technology for

Once your SPARQL queries get bigger, you may stumble over the problem that you have duplicate parts of the query or have to deal with performance impacts.Federated queries are affected by some more constraints.The SPARQL Named Query proposal allows the ex…

The RDF community does a pretty good job writing code around specifications.But there could be more generic code that supports people testing or implementing algorithms for RDF graph data.There are many tiny libraries on my local machine which fit into th…

Maybe some of you watched more videos than the years before.I guess this will be the case in 2021 as well.That’s why I wrote down this summary of my favorites of 2020.

Finally I fixed some small issues in my first design for the case for the ReSpeaker Core v2.0 board.Now you can download it at Thingiverse and print your own!

Finally RDF-Ext v1 is here!
