[Nepomuk] Brainstorming: Metadata Sharing

[Daniele E. Domenichelli]

Hi!

Another couple of ideas about metadata sharing that I was thinking about
during the flight.

1) Someone might want to be able to query for all tags or other
relations created from particular persons, for example all tags for a
particular song that were set by people from x to y age that live
somewhere and whose sex is m or f.
Of course there are related privacy issues.

2) About privacy issues, you could also think about something like a web
of trust for sharing data, so there could be several levels of trust,
for example:

  *Untrusted*: default level, doesn't share anything.
  *Marginal*: share only anonymous stuff (tags, etc)
  *Full*: share all knowledge with a contact and anonymous information
          with friends of this contact that are at least of marginal
          level
  *Ultimate*: Share all knowledge with a contact and with all contacts
              that are at level full or ultimate and anonymous
              information with friends of this contact of marginal level
