Re: Firefox 3.0: template using RDF in-memory-datasource

When starting with datasources="rdf:null", it seems the only way to get a template to display is to set the datasources attribute. Calling methods on tree.database (AddDataSource, refresh, rebuild) seems to have no effect.

Depending on what operations you need to be able to support you might 
find it easier to rewrite the code to use a custom tree view. 
Alternatively for debugging purposes you could try hard coding the 
datasources to be a path to a local file on your machine, then you can 
flush the data source to see the effects of your RDF manipulations 
(assuming you can read RDF/XML) or simply use the output as a convenient 
source of test data.

Registering datasources with the RDF service runs into reference count 
issues.

No, it's just that although there are some things that RDF does very 
well, there are also lots of things that it does quite poorly and 
nobody's interested in being responsible for improving it.

Any documentation should exist on the developer.mozilla.org wiki.
