[Zope-CVS] CVS: Packages/Moztop/idesupport/rdf - container.py:1.3

[Stephan Richter]

Update of /cvs-repository/Packages/Moztop/idesupport/rdf
In directory cvs.zope.org:/tmp/cvs-serv24088/idesupport/rdf

Modified Files:
	container.py 
Log Message:
- We now have the sense of a first static TypeRegistry. Much more work is 
  needed in this area.

- If you have an image, you can now save its meta data and see the Upload
  screen. Trying to open the File Picker somehow crashes my Mozilla.

- All types that Zope supports are now listed and can be handled in the 
  contents.rdf file.
