There’s a tension between being semantically rich (using your own terms and definitions), and being semantically aligned, in which you try to reuse terms from other vocabularies.

I think we need a new concept: eventual #interoperability. I propose to start rich with your own vocabularies, and only make alignments when there’s a concrete reason for building those.

Eventual Interoperability – Pieter Colpaert

A pragmatic approach to interoperability: model your data richly for your own needs, then allow the eventual creation of one‑to‑many alignments.

Scholarly archives blocking access to AI agents is not what I want as an author: I paid publishers to archive and make available my paper as open access, that certainly includes making sure that an LLM can take into account my paper when answering an expert’s question...

This is pretty cool: @sovtechfund@mastodon.social has a CfP open for people who want to be funded to work on standards: https://www.sovereign.tech/programs/standards

Would be more than pleased to support applications to help out in the W3C groups on TREE hypermedia, RDF Stream Processing (I’m working on RDF Messages there), RDF1.2, ODRL, DPV, Dataspaces, Knowledge Graph Construction, Linked Web Storage, or JSON-LD. Ping me if interested!

Did someone already complain about daylight saving time here? In case not:

Abolish daylight saving time!

Kind regards,

Someone with kids

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.

Creating the standard is often just the last step once we already agree on 90% of it.

Don’t equate #interoperability with #standardization. The process of creating interoperable solutions involves so much more.

“Zero token flows” – data flows that don't require any LLM intervention, yet work fully automatically

Today we’re welcoming Flanders’ top researchers in Data and AI in Ghent for the closing event of #SolidLab. Where we’re continuing the community under a new name, #Trustflows.

We’re still working on #interoperability, but we’re now adding #legalcompliance and #trust as major drivers. Trustflows continues the mission we started with Solid.

Want to know more? Take a look at the website: https://trustflows.eu

With the #Trustflows community, we’re launching #TrustTriggers:

A new event series combining a cross-domain Trustflows topic, a long networking break, and 3 concrete use cases.

First edition: 20 April at De Krook in Ghent. With curator @besteves4@eupolicy.social hosting a discussion on the EUDI with invited keynote speaker Jan Lindquist.

We’ll also discuss use cases such as DPP, local council decisions, and trigger in the water domain.

Program and registration: https://trustflows.eu/events/2026/04/trust-triggers-1/

Trust Triggers #1: The EUDI – Trustflows.eu

Trust Triggers #1: The EUDI – Trustflows.eu

First Trust Triggers event with a keynote and reflections on the EUDI and Wallets, and three Trust Trigger use case pitches.

@nichtich @danbri they now use their own semantics that will get eventually aligned ;)

@bencomp@code4lib.social yes, so multiple aligned views on the same source semantically rich data. Eventual interoperability is not in contradiction with that idea, it just proposes to do one after the other to make that idea way more effective

@stroobl did you bring data (on the level of Belgium/Europe) as proof? I'm skeptical!
