Many websites allow users to assert relationships between other users, to upload contacts and to invite their contacts to become users.
The project aims to provide a Django app for this sort of functionality. This includes:
- relationships between users (possibly with different types of relationship)
- sending and acceptance/rejection of invitations
- management of contacts who are not yet users (and notification when they become users)
- generation of FOAF files
- import of vCard and other means of importing contacts
