IMO exif.js contains all the functionality, that is needed to extract the 
different values. 

One problem I see is, that the value description is hard-coded english 
language. For a TW plugin, we would want that to be translatable.

That's a point. Especially, since TW uses the DOM src-element if an image 
is imported with _cannonical_uri. .. This means: all the work is done by 
the browser, when it shows the image. TW does almost nothing with the image 
data. ... So we would need a way, to extract the exif data, after the 
browser did load / show the image.

I think, that's obvious. All the image related data can be stored and 
distributed with the image. TiddlyWiki is "just" the app, that lets you 
have a nice presentation of this data. ... I do like the idea.

That's right.
