# Groupware Address Book

The **Groupware Address Book** is a module within the [[groupware]] collaboration platform provided by the [[universitatsrechenzentrum-urz]]. It allows university members to manage personal and professional contact information.

## Features
- **Personal Address Book**: A private list for the user's own contacts.
- **Custom Address Books**: Users can create multiple additional address books beyond the personal one.
- **Sharing**: Address books can be made accessible to other users through the use of [[acl]].

## Interface Layout
The module is organized into four primary functional areas:
1. **General Functions**: Used for adding or removing contacts and accessing the **Administration** button for ACL settings.
2. **Address Book List**: Displays all created or shared address books; defaults to the personal address book if no selection is made.
3. **Entries**: Lists the individual contacts within the currently selected address book.
4. **Details**: Displays the full information for a specific contact selected from the entries list.

## Compliance and Privacy
In accordance with [[gdpr-compliance]], the following restrictions apply:
- **Purpose Limitation**: Storage of personal data is permitted only for official business purposes.
- **Sharing Restrictions**: Information that is not strictly necessary for service fulfillment (such as birth dates) must not be shared with other users via ACLs.
