[jsword-devel] jdom removal

[Joe Walker]

Sigh - I think the document model in JSword is one of the things I most consistently got wrong. If I remember correctly we started with a standard API, then JAXB then JDOM.
At the time XML seemed like The Future, however there seems to be more and more that argues against that vision for JSword:
- Android display works around the JSword API to avoid XML
- Swing uses the horribly broken JEditorPane (?) and its display is probably the worse for it
- Even using XML for JSword on the web, which should be a sweet spot, has (had?) problems like getting reliable XSLT in browsers.

We're going to need some sort of document object model, and given the existence of OSIS, some sort of ability to serialise it to XML makes some sense, but perhaps we should consider an object model that is somewhat closer to the storage model than the display model.

Joe.
