Federated Object Sharing Protocol

Hi Federated Social Web group,

More than a year ago I wrote to this mailing list asking for related
work for my Bachelor thesis. The thesis is written and now I'm working
on a documentation of my new protocol.
I promised to share my work with you so now here it is.

A small abstract on what to expect:
FOSP is a protocol that allows sharing arbitrary data, setting access
rights on the shared data and receiving notifications on changes.
Furthermore, all features of FOSP can be used in a federated network,
e.g. between multiple independed providers.  It was designed to be
the most simple solution that combines all these features.

As this is the first protocol I designed and the first RFC I write, I
would be very happy to receive some feed back on the protocol and also
on the documentation.
The current version is not complete, not accurate, might not be easy to
understand and might even contain some wrong/outdated information.
Furthermore I reserve the right to make significant changes to the protocol.
Still I feel like I should advertise it to a larger audience now, at
least to build up pressure on myself.

Everything is also available online on
https://github.com/maufl/fosp-specification.

I hope it will be interesting to some of you.

Regards
Felix Maurer

PS: Of course there already is a working implementation.
