IIIF and Geodata: A Careless (LOUD) whisper

Andy Irving - (British Library)

Presentation type: Presentation


Georeferencing images has been commonplace in our communities for many years, from before we fully embraced the web. The IIIF Image API has, for a long time, described in the annex a GeoJSON service. Commercial services exist which consume and display images using the IIIF API, but they do not make use of this service. So what practical steps can implementers and consumers take to expose and make use of this data, and how can we link it to the pixels? In this presentation, I will give an overview of the problem domain, the technical hurdles to overcome, and some demonstrations of what I think is the right direction (pun intended)


  • Linked Open “Usable” Data (LOUD) and IIIF,
  • Interoperability in IIIF contexts
