I have been interested in personal knowledge management (pkm) for a very long time. I have been an avid notes maker ever since I learned to write. Digital tools from the late 1980s onwards have been extremely useful. And a source of nerdy fascination, I confess. I am certain personal knowledge management (pkm) is of tremendous value for anyone who wants to keep learning and make sense of the world around them.

On March 20 and 21 the European PKM Summit is taking place for the third time in Utrecht, Netherlands. I’ve helped a bit, like for earlier editions with suggesting speakers and workshop hosts for this event.

I am donating a ticket for a student in the Netherlands to attend this two day event. I did the same last year and the year before.

Are you a student at a university in the Netherlands (doing a bachelor’s or master’s) with a strong interest in personal knowledge management (pkm)? (note that it says interest, I don’t expect you to be highly sophisticated or experienced in it!)
Is your interest in pkm to strengthen your personal learning and deepen your interests, rather than increasing (perceived) productivity?
Would you like to go to the PKM Summit on 20 and 21 March in Utrecht, but as a student you cannot afford the 254 Euro ticket price?

Then I have one (1) conference ticket available! Let me know who you are and what fascinates you in pkm or attracts you to the event. If there are several people interested I will choose one. I will donate the ticket a month before the conference, by February 20th, so state your interest before then.

The single condition is that you attend the event on both days and participate actively in the sessions. If you have other ways to attend (by e.g. volunteering for the event staff) then that is preferable. This is specifically for someone who would otherwise not be able to go. I’d be happy to briefly meet you as well at the event, but if not that is perfectly fine too. It would be great however if you would share some of your impressions of the event afterwards online on the open web, especially if that is something you’d normally do anyway.

Interested? Email or DM me (in Dutch, German or English)! My contact details are in the right-hand sidebar.

Favorited SEMIC2025 Trip report by Pieter Colpaert

Pieter Colpaert, we go back to since the early open data days, reports on his takeaways of the SEMIC conference last November in Copenhagen, under the Danish EU presidency.

I enjoyed the conference too. For meeting friends like Pieter. But also to see how geopolitical shifts and the urgent need for digital sovereignty landed. It seemed many for the first time realised that interoperability is a key element in digital autonomy and sovereignty.

SEMIC is a conference bringing together the European Semantic Interoperability Community.

Twenty years ago today E and I visited Reboot 7 in Copenhagen. What I wrote a decade ago at the 10th anniversary of that conference still holds true for me.

Over time Reboot 7 became mythical. A myth that can’t return. But one we were part of, participated in and shaped.
Still got the t-shirt.

Seventeen years ago today I blogged about a barcamp style event in Amsterdam I co-hosted, called GovCamp_NL. I struck up a conversation there about open government data after having had a similar conversation the week before in Austria. It marked the beginning of my work in this field. We just welcomed the thirteenth team member in the company that over time grew out of that first conversation. Our work at my company is driven by the same thing as the event, something I’ve come to call constructive activism.

These days, the principles and values that drove those events, and have set the tone for the past two decades of everything I’ve done professionally and socially, seem more important than ever. They are elemental in the current geopolitical landscape around everything digital and data. We can look back on our past selves with 20 years hindsight and smile about our one time optimism, because so much exploitation, abuse and surveillance grew out of the platforms and applications that originate in the early 00’s. But not because that optimism was wrong. Naive yes, in thinking that the tech would all take care of itself, by design and by default, and we just needed to nudge it a bit. That optimism in the potential for (networked) agency, for transparency, for inclusion, for diversity, and for global connectedness is still very much warranted, as a celebration of human creativity, of the sense of wonder that wielding complexity for mutual benefit provides, just not singularly attached to the tech involved.
Anything digital is political. The optimism is highly political too.

The time to shape the open web and digital ethics is now, is every day. Time for a reboot.

This week at the EU Open Data Days in Luxembourg, Davide Taibi a senior researcher at the Institute for Educational Technology of the National Research Council of Italy, talked about his research into a possible European curriculum for data literacy.

He mentioned how, in the highly multilingual context of Europe, data literacy is an unclear term. In German data literacy translates to data competence, while literacy itself translates to alphabetisation. Other terms like information literacy and data science are used more commonly across countries.

On one of his slides (image) he wrote:

The term data literacy isn’t well known in most of the countries analysed. The most widely used terms are ‘digital literacy’, ‘information literacy’, ‘data competence’, ‘media literacy’, ‘statistical literacy’, ‘computer/IT literacy’, among others. In most countries it is closely related to digital skills.

I usually use Howard Rheingold’s shorthand for literacy as skills plus community. Skills benefit individuals, but for some when you add in the context of a community or network of skilled people in which that skill gets deployed, the value of usage sees a nonlinear effect, a kind of network effect basically. That communal aspect, and the jump in usage value is connected to my notion of networked agency. It works as a multiplier.

Looping back to the lack of clarity around data literacy as a term, I wonder.
Is it because we haven’t yet described clearly enough which _skills_ we mean when talking about data literacy?
Or is it because we don’t really know which communities would see which non linear use value, when deploying the data skills concerned?

During the PKM Summit last week I saw Zsolt Viczián do several amazing things with his Excalidraw plugin in Obsidian as part of his visual thinking efforts.
I’m very much a text person, but do recognise the role of visual elements as part of my thinking process. Shifting concepts around, thinking about connections, clustering etc. It engages the spatial parts of the brain, and humans are good at that. As most tools do either one thing or the other, when a tool can do both as just different perspectives on the same thing that draws my attention. It is why I’ve used Tinderbox and e.g. The Brain. Zsolt showed me how Excalidraw in Obsidian can do both too. Any Excalidraw-in-Obsidian image can have a regular note on the other side, and you can switch between them. All this because it’s just one note in markdown with some parts interpreted by Excalidraw and other parts by Obsidian.


A sketch of the elements needed to post my own slidedecks in a nice viewer, now that I’m no longer satisfied with how I’ve ‘brought slides home‘ the past four years.


The same file but now shown as text, where I’ve written a few tasks as part of creating the setup I’ve sketched in the image. Zsolt calls this the backside of the image. I’m more reminded of Tinderbox where you could see something as outline, as timeline, as tree map, as canvas etc. all interchangeable.

Zsolt very much gave me a great nudge to play with this more, and relearn that I do care about visual elements in my notes, and that it’s just that it wasn’t easy enough to build into my routines in making notes.
