Can you please elaborate? Are you using the python API? If so,
Activity.metadata contains a dictionary with all the properties for
the current object.

What if you serialize the whole entry (file + metadata) inside a zip
file and distribute that?

The journal has already support for installing to the DS these
serialized entries:

Added because of http://dev.laptop.org/ticket/4380 .

Hope that helps,
