I've begun looking around at the best options for JavaScript libraries and the like, for building the GUI for GR's database. I haven't written this stuff in a while, so I wasn't up to speed with what's available. These are some things that strike me as practical:

• ExtJS looks like the best GUI toolkit around. Unfortunately there seem to be some issues with its support of strict XHTML; that will need more attention before we can settle for it.
• The Fck Editor (2.6) looks ideal for rich text editing forms. It does support XHTML.
• This IBM project looks promising for JS to db connectivity.
• There are numerous options for AJAX, assuming the above project doesn't handle all our client/server needs; I need to do more research there.
