I want to add the capability to load and save Small Device and other formats
from within OOo. This will be accomplished by means of the XmlFilterAdaptor
(framework/filter/source/xmlfilteradaptor)code which can be used to access the
XMergeBridge. This module in turn accesses the xmerge filters.

With this code, standalone converters written with the XMerge framework, can be
incorporated into OpenOffice, just by editing the TypeDetection.xml file.
Currently Xmerge supports the following:
 AportisDoc 
 PocketWord
 PocketExcel
 XSLT (which allows users to use there own transformations)
For more information see http://xml.openoffice.org/xmerge

The XmlFilterAdaptor is an XFilter implementation which can also be reused to
create normal OpenOffice filters. It provides a standard set of interfaces which
can be used by filter writers to easily access elements of userdata. 

A sample of a regular filter which has been written to use the XmlFilterAdaptor
also exists. It is a Flat xml reader and writer which saves an OpenOffice file
as flat xml. Not only does this code provide a good and clear example of how a
filter can be written, it also provides functionality that has been requested on
openoffice.discuss.
