Description Thorsten Schäfer

Often plugins need to maintain state at plugin level or per project. Projects 
allow to save project properties - but it's only possible to save strings 
there. Because I think that saving state is a common task for most plugins, I'd 
appreciate if there's a possibility to save objects for a plugin/project 
without having to implement the persistence mechanism. E.g. the platform could 
support the XML (de-)serialization of objects.

Plugins can obtain a per-project private metadata area with
IProject.getPluginWorkingLocation.

Yes, I know, but I think it would be useful to have a framework service for 
persisting objects instead of implementing a persistence service in every 
plugin.

JDK 1.4 already includes JAXP APIs for (de)serialization of XML.  I'm going to
mark this as a dup of the user settings plan item, which may include API for
storing richer per-project settings.
