- Tracker finds relationships between data over content. Song A and Song
B are form Artist Y who is from the same hometown of Artsit X
- Zeitgeist finds relationships between data over usage. Last week "
google.com" and "Project A" were used alot together. So google is now in
relationship with "Project A". In a month the relationship will expire
because I am done with Project A. So "google.com" is now not in
relationship with "Project A"
Zeitgeist is an event aggregation framework that just makes sense of events
happening on the computer. We have a defined format for how events should be
understood. We don't extract metadata ourselves. The metadata is extracted
by the applications that send the events since they know more about their
docs then anything form the outside.
A typical Zeitgeist usecase would be providing documents most used with
other documents or recently used with recent documents. Other usecases would
be notifying applications with events of interests. Such as notifying
parental control with any events with metadata related to porn etc...
Zeitgeist plays along well with CouchDB and Tracker:
Zeitgeist aggregats and logs events form apps! We try to make sense of
incoming events (which documents are still open thus share tags etc...)
The engine uses a felxible DB module that allows us to use any kind of DB.
This is intended to later store individual events into the Tracker storage
and team events into a CouchDB storage.
