To help ensure usability of the new APIs, I’ve created some example clients

• http://lucas.ucs.ed.ac.uk/oarj/index.html shows the sort of thing the main api can do.
• http://lucas.ucs.ed.ac.uk/oarj/example_get.html shows some of the power from the get_* calls.
• http://lucas.ucs.ed.ac.uk/oarj/example_list.html allows you to see what data is returned via the list calls

Most of the calls are done using JQuery, which has a mechanism for doing CrossDomain calls – and all the scripts support that functionality if you want it.
