Seadragon and the World Digital Library

As you probably already know, the World Digital Library opened yesterday.


(By the way, the functionality of the demo does not seem to be implemented yet ... or am I looking in the wrong place?)

It would seem, where does Seadragon ?

Looking through the collections collected on the site (from all over the world) and looking at the suspiciously familiar behavior of the “viewer”, I wondered what it all worked on ... And this is not Flash or Silverlight!

We climb into the code ... and see very familiar lines of code:

< script type = "text / javascript" src = "/ static / js / aggregate / seajax-min.js " > </ script >

And further along the code:

var WDLBookData = { "file_ext" : "tif" , "pages" : [{ "dzi" : "/static/c/201/service/zoom/0001.dzi" , ...

Yes! These are the Seadragon Ajax and DeepZoom image collections!

The rest - a digital library built on Django, nginx, Lucene / Solr and mySQL DB. In addition to Seadragon Ajax, jQuery is involved in the client side.
