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?

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!

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.)

Bot traffic included, for sure. But the real pain: no way to know who’s using it or what for. Such is open source... www.jsdelivr.com/package/npm/...
