Hi -

This is a very cool tool. I am glad to see JPEG2k stuff hitting the
open source world. Very nice!

That said -

It would be nice if somebody could make this work without OpenURL.

Frankly I would much prefer the normal URI:

http://an.example.org/ds/CB_TM_QQ432?level=4&rotate=0&y=899&x=1210&h=657&w=1106 [1]

to the OpenURL:

http://an.example.org/djatoka/resolver?
    url_ver=Z39.88-2004 &
    rft_id=info:lanl-repo/ &
    svc_id=info:lanl-repo/svc/getRegion &
    svc_val_fmt=info:ofi/fmt:kev:mtx:jpeg2000 &
        svc.format=image/jpeg &
        svc.level=4 &
        svc.rotate=0 &
        svc.region=899,1210,657,1106

and - so does the web, generally, consider that nobody uses OpenURL.

I notice also that the example ajax tool put a duplicate URI box in
the lower left hand corner for permanent URIs. It would be nice to
have a ‘bookmark this’ type link - as in google maps, if the current
bookmarkable URI is not going to be reflected in the location bar.

best,
Erik

1. I have left out the HTTP Accept header, part of the HTTP request
but not part of the URI which is a more expressive replacement for the
svc.format=image/jpeg parameter.
