And once again, don't you think supporting metadata ("Name, value") directly in

an
osg::Object (or another given type), read from/write to file using
UserData->serialize()/unserialize()" in reader/writers?
Having the serialize/deserialize as part of the object isn't a good idea, because it
doesn't allow you to deal with different formats, such as .osg and .ive? This must be
implemented in the respective plugin but for pure key/value pairs this could be added to
the .osg and .ive plugins.
How about having a osg::KeyValue object derived from osg::Referenced so that it can be
used as user-data?
That would also allow other plugins to return additional information, like an image loader
to pass additional information (like description, fps, colourspace, and such) back to the
application in a standard format.
On the other hand there is the problem with typing the contained data and name
collisions...
