Hi Igor,

We talked about this last year, and the problem with serialization is the
constraints placed on the format with respect to API.  Once we declare the
p2 metadata serializable, it would seem that you could read / write the data
without worry. However, if a new field is added to the metadata, this
assumption will break.

FWIW, a while ago I experimented with my own class structure that mirrored
the metadata (for each class associated with the p2 metadata, there is
a corresponding interface -- so this isn't too hard). I maked these as
serializable and
used this format.  While it was better / faster / smaller than the
compressed XML, the results weren't that impressive.

HTH,
Ian
