[Nepomuk] Brainstorming: Metadata Sharing

[Vishesh Handa]

I wanted to start with Metadata Sharing, but I don't have a clear idea as to
what it entails or how I'd go about it. So I thought we could discuss it. :)

This is what we have so far -
1. Jabber should be used to connect to another user's system.
2. We should be able to perform queries on another users system, connected
via Jabber.
3. Some form of privacy lists which filter other users searches and only
return the content the user wants sharable.

Jabber is a nice way of sending the sparql query. but maybe we could look
into other things like UPnP. Anyway, that's a secondary concern.

Metadata sharing implies that we should be able to see other people's
metadata and have it on are own system. Sebastian suggested that we store
user information ( who owns which statements ) as graph metadata. That's
totally feasible, and maybe we could also store the permission settings as
graph metadata.

I'm not too sure how we would choose whose metadata to store our on system
or why we would need to do that. I always thought we would have something
like this -> Search for a person John Doe, turns out we have a contact by
that name but a friend of ours has some pictures in which he has been
tagged. On further investigation we find that we have the same pictures. (or
we could get those photos , file sharing? ) Then we *sync* the metadata of
those pictures. With the current backup-sync framework that syncing part is
possible, but maybe this is where we would store the other user's metadata
on our system AND mark them as created/owned by that user. (Sharing?)

Any thoughts?
