Knowledge Plaza's rights model is quite complex, which also makes it really powerful. Here are two tables, one enumerating rights on workspaces level, and the other on the Plaza itself.

• to any fully visible Tile (metadata + content)
• in public workspaces

• Full view for anyone
• Full view for Workspace members, reference for anyone else
• Full view for Workspace members only, invisible to non-members
• Full view for owner only, reference for anyone else
• Full view for owner only, reference for Workspace members, invisible to non-members

Besides, workspaces can be either public or private. If a workspace is private, non-members won’t see it, except Plaza administrators.

Also, each user has its own individual private workspace. All its content is totally invisible to others.

Users can though give access to hidden or restricted Tiles by sending them to other users, using the 'Send' functionality'.

Rights on original contributors can’t be revoked, even after leaving a workspace where they added Tiles.

Finally, Plaza guests won’t be able to access any workspace (even public) except if they are at least guests in those workspaces.
