The #MachinaEmblematica – our mysterious chatbot guide into the 16th century encyclopedia "Symbola et Emblemata" is now reasonably mobile-friendly.

Check it out if you haven't already!

Cold and rainy but good fun at the annual Science Day in Leuven where we demonstrated how anyone can easily collect and work creatively with high-quality images streamed from cultural organizations globally. #dvdw2025 #IMMARKUS

We built #MachinaEmblematica as an outreach/engagement tool rather than for research. But as someone with zero knowledge of 16C emblem books (or Latin!) I find it an amazing way to poke around & discover odd new things—far richer than randomly browsing #IIIF images alone.

@rockettara.bsky.social and I've been teaching the #MachinaEmblematica some new tricks: better image interpretation and conversational context, smarter source retrieval from the Symbola et Emblemata. It’s a bit slower now… we’ll work on that next. 😉

text-annotator-js – our JavaScript library for text and PDF annotation – is looking for a new name.

Something shorter, nicer and more memorable. (Current favourite: "leuchtmarker" – German for "highlighter pen".) Got ideas? Drop them below!

Better Project Name · Issue #238 · recogito/text-annotator-js
The name "Recogito Text Annotator" was actually meant as a temporary working title. As always with working titles, it stuck... IMO it's both land and a bit too verbose. Also: it's currently under t...

Our #MachinaEmblematica has a few quirks. But if you ask for specifics of a particular page or emblem, I feel that the multimodal model generates pretty useful responses!

Trying a new approach to my overlapping annotations problem:

• No more stacked underlines
• Instead, overlaps get small start markers
• Exact overlaps show a tiny count number
• Color density still hints at overlap

Try it live: dense-annotations.netlify.app

One caveat… see next post 👇

Here's my main dilemma with overlapping text annotations: Underlines become a mess once you stack more than three. At the same time, there's really no way around them if you want to show where overlap starts and ends.

I guess the Q is how/when to drop underlines without losing too much information?
November 4, 2025 at 2:13 PM
Task for today: brainstorming better ways to visualize heavily annotated text. The more I think about it, the harder it gets...
• Partial overlaps → clutter & a11y issues
• Exact overlaps → even worse
• Stacked underlines → work great... until they don't.

Seen elegant solutions? I’d love to chat!

Had the chance to join a workshop on image annotation in IMMARKUS led by @hildedw.bsky.social, Rainer Simon, Sunkyu Lee, and Dawn Zhuang today. This was great fun and definitely a tool I will use when working with visual media and texts in the future! #digitalhumanities

We’re improving accessibility in the Recogito Text Annotator, our open source text annotation library.

Keyboard support is solid, but highlights aren’t directly tied to the text. They're a floating layer above it, breaking screen reader access. If you’ve faced similar a11y issues, I’d love to chat!

Arrows between annotations - a recurring feature request I’ve revisited a few times. Building yet another version in a current project:
• Hand-drawn (no auto layout)
• Can snap to annotations - or not
• Works as both a visual tool & a semantic/data-model link

This feels like the nicest version yet!
October 10, 2025 at 1:10 PM
New in #IMMARKUS: when you import a #IIIF manifest, IMMARKUS now imports existing annotations (embedded or referenced) into your workspace.

We'd love to test with real-world examples. If you know of IIIF collections with annotations, let us know. Annotated manifests still seem rare in the wild...

The Recogito PDF Annotator now applies better post-processing to the annotation highlights.

The differences are subtle. But I like how those gaps, uneven line height and messy overlapping box artefacts are now smoothed into clean, continuous lines.

A question for #DigitalArtHistory: If you were to create a small online image database (with IIIF support) right now, which software would you choose? Fylr (ex easydb), Coneda KOR, something completely different?

Been using the Smart Scissors tool in liiive.now for a while & it's been working pretty well.

There's still a small memory leak somewhere... If it hangs after longer use: refresh the page. (Nice thing about liiive: annotations are always saved, you won't lose data.)
