Chronoscope World
A IIIF viewer from both sides of the screen

IIIF Friday, 23-Feb-2024, 2pm CET

Chronoscope World is a user-centred tool to browse shared cultural heritage media from IIIF providers world wide.
It predecessor, Chronoscope Hamburg, has started as a maps webapp in 2016 with 4 old maps. Since then, more than 7,200 IIIF maps have been georeferenced and can be studied at their correct location on a global map. Context info allows to browse seamlessly across 80 openGLAM institutions. The user can search and filter by place, timeframe, scale, cartographer, subject, or archive. Due to the fact that Chronoscope can display maps in IIIF format, it can also display IIIF books (with special map pages inside) or just any online 2D media such as old photos or paintings from art museums.
Import should be as easy as drag ’n’ drop. In fact it is. The user can drag any IIIF manifest link into a Chronoscope browser tab to display a matrix of thumbnails. 60 libraries even support smart drag ’n’ drop, i.e. the user can drag the item’s preview images from the search results page to the Chronoscope, rather than hunting for a IIIF link on the archive page.
The presentation will provide a live demo and reveal some algorithmic tricks on the other side of the screen.

...I just wanted to add that the drag and drop feature is so wonderful because it really bypasses one of the major obstacles of use of images and metadata in IIIF format. For end users it is such an obstacle for them to go and to click on a thing that says iiif manifest. And they have no idea what that means. And then have to copy it in a viewer that they have never heard of. So kudos to you -Matthias- for the drag and drop feature. - Evelien

Wim: Wonderful tool and excellent presentation Matthias, thank you so much!
Wim: Hoogtepunten: de presentaties van Allmaps van Jules Schoonman, Bert Spaan en Manuel Claeys Bouuaert (TU Delft) en ChronoScope van Matthias Müller-Prove.

Femke: Did Matthias design a very efficient shortcut vewer, skipping 5 steps? Chronoscope can be used in general then, not just for maps :) Great!
In general on technical systems like IIIF: WYSIWYG through easy user friendly interface like drag and drop could lower the threshold and putting people off? Thus all the systems including Madoc and others work for us as a tool to reach our goals instead of the other way around....

I'd be happy to receive and read your feedback via_
