(Full RFC at http://wiki.koha.org/doku.php?id=en:development:rfcs3.2:rfc32_ajax_in_the_staff_interface)

Currently, in the svc/ directory and tagging tools, there are some cautious forays into using AJAX. However, many more areas of the staff (and possibly patron) interface could be improved using AJAX and well-structured web services.

Towards this end, LibLime has made patches for AJAX usage on the circulation and issuing rules editor page. These patches make use of new Perl modules, and are based as much as possible on REST principles.

MJ: Yes, the AJAX degrades. It even has its own system preference for the circulation screen.
