public class Project
extends OwnedItem<ProjectData>
implements Nameable, Removable, ToTransferable<ProjectInfo>, Registered

This class is used to represent projects. A project is used to collect items of particular interest in one place. Users and groups can also be granted access to projects, allowing everyone easy access to shared items within the project.

While working with BASE it is possible to set one project as the active project. This enables some useful functionality in the core:

• Every Shareable item the user creates is automatically shared to the project.
• All queries defaults to only return items that are shared to the project.

It is also possible to add an item to other projects, or remove it completely from all projects. Every member of a project has a special project permission which gives the highest permission for accessing items in the project. Normally this permission is Permission.USE. One person might be assigned administrator of the project and given higher permissions.

Items may also be given a permission within the project. The normal is to give full access, but it may also be set to for example Permission.READ. Then, not even the project administrator will get more than read permissions to the item. This feature can for example be used when a project needs to access data from a user that is not a member of the project.
