# Groupware Address Book Administration

Groupware Address Book Administration refers to the management of contact lists and their associated access rights within the [[groupware]] collaboration platform.

## Administrative Workflow
To modify address book properties, users must:
1. Navigate to the **Address Book module**.
2. Click the **Administration** button in the toolbar.
3. Double-click the specific address book from the list to open its properties.

## Access Control Lists (ACL) and Permissions
The system employs a granular permission model to control who can interact with specific address books. Rights can be assigned to either individual users or predefined groups.

Available permission levels include:
- **Read**: Users can view the contacts.
- **Write**: Users can add or edit contacts.
- **Admin**: Users can manage the properties and permissions of the address book itself.

## Data Portability and Import
The platform supports the migration of external contact data into the Groupware environment. This is achieved through the **Import** tab, which supports multiple transfer formats, most notably **CSV** files.

## Cross-Module Integration (File Module Side Effect)
A critical technical characteristic of the Groupware implementation is the link between the Address Book and the File module. When an address book is shared with other users via the ACL, the names of the entries are automatically mirrored as a **folder structure** within the **File module** for those authorized users.
