Investigating mozilla webdav

A long while ago, I investigated midgard/mozilla integratation, as part of the latest efforts, I've got webdav publishing working quite nicely with mozilla, and a midgard like database, however what it really needed was a sidebar to navigate the article tree, and click to edit functionality.

setting up a sidebar panel is not that difficult, it's just a small javascript call to

window.sidebar.addPanel ("Vending","http://devel.akbkhome.com/vending.xul ","");

which adds a sidebar and points it at a url, either a html one, or a xul one. - xul has lots of nice features, like tree views which can pull data from rdf files, however after quite a bit of investigation, it became obvious that due to the security model of mozilla it was imposible to do any kind of javascript call to open in an editor window from the sidebar (yeah sidebars can appear in the editor).

The other issue that became complex was the heiracical loading of trees, - a typical midgard type tree can be quite large, and ideally you would not want to pull down the whole tree in one go. Mozilla has a few tricks to work around this, using javascript to build the trees manually however this again proved very time consuming and hit and miss as far as results go.

In conculsion, to attack this problem again, It would probably involve a number of components. an xpi installed webdav/rdf editor navigator, that you could point at a url (using some kind of preference box), then the rdf data would be given out from this url.
