The FOAF module enables the following:

1. automatically import/synchronize profile information between any Bryght- or Drupal-powered sites
2. import profile information from external FOAF files
3. export a FOAF file based on a user's profile

For profile synchronization, when you login to site A using your account information from site B, your site A profile automatically gets filled with values from site B - presuming that both A and B have the FOAF module and the drupal.module enabled.

This module will also export your buddylist if buddylist.module is enabled.

The fields selected for this module are intended to conform to the FOAFnet specification.
