Extension point permissions

Documentation

Extension point to register permission definitions or override existing permissions.

Example to define a single atomic permissions that are not meant to be displayed in the rights management screen of folders:

    <permission name="Browse"/>
    <permission name="ReadVersion"/>
    <permission name="ReadProperties"/>
    <permission name="ReadChildren"/>
    <permission name="ReadLifeCycle"/>
    <permission name="ReviewParticipant"/>

Example to define a compound permission that holds many related atomic permissions into a single high level (role-like) permission:

    <permission name="Read">
        <include>Browse</include>
        <include>ReadVersion</include>
        <include>ReadProperties</include>
        <include>ReadChildren</include>
        <include>ReadLifeCycle</include>
        <include>ReviewParticipant</include>
    </permission>

Note that each of the included permissions should have been previously registered with their on <permission/> declaration.

It is later possible to override that definition in another contribution to that extension-point to add a new permission 'CustomPerm' and remove 'ReviewParticipant':

    <permission name="CustomPerm"/>
    <permission name="Read">
        <include>CustomPerm</include>
        <remove>ReviewParticipant</remove>
    </permission>

Eventually the permissions declaration also accept 'alias' tags to handle backward compatibility with deprecated permissions:

    <permission name="ReadVersion">
        <documentation>
            The Version permission is deprecated since its name is ambiguous,
            use ReadPermission instead.
          </documentation>
        <alias>Version</alias>
    </permission>

NB: the alias feature is parsed by the extension point but the underlying SecurityManager implementation does not leverage it yet.
