I concur, in order to avoid disrupting existing users, metadata should only be read/written to if UserData is empty or already contains a metadata object. Possibly we could have an abstract "metadata" or "de/serializable" interface so that users could retroactively support their existing UserData objects without needing to use to the new classes for storage. I hear that osg 2.9/3.0 also has a new serialization framework for node files? (I'm using 2.8)
With regards to implementation, I would be possibly be able to work on something as I do have a use for it, but I won't be able to get to it for several weeks at least. If someone has a more immediate need (Sukender?), they should step up. On 2/3/2011 11:21 AM, Sukender wrote: > Hi Bob, > > Ulrich is right: you could move your data as a metadata.
