Permissions and inheritance
GitBook has a flexible permissions model that lets you have as much, or as little, control over permissions as you need. The permission model in GitBook is a role-based, cascading model. This means that you set defaults and then, at any level of content, decide whether to inherit those defaults or not.
Any time you create a collection or a space, you'll be able to set the type of inheritance you want. You have three broad options when setting the inheritance for a piece of content:
Setting the inheritance to inherit will make the space or collection inherit the roles assigned in the parent level content. For top-level spaces or collections, this parent is the organization, so they would inherit the organization default roles. For spaces or sub-collections inside a collection, the parent will be the collection the content sits within.
Selecting a specific role when setting a collection or space's permission inheritance will reset the organization default roles and assign every non-admin to that role within the collection or space. For example, if you set the inheritance to reader, everyone in the organization would have read-only access to the space or collection, regardless of their default role.
You can also completely revoke access for any non-admin organization members at a space or collection level. This will hide the content from everyone except for admins and whomever created the space or collection.
Once you've decided on the permission inheritance for your space or collection, you can further customise access by giving teams or members direct access.
You can add a team directly to a collection or space with a specific role. This will give anyone in that team the specified access to the content.
Similarly to teams, you can also give members direct access. This is the most granular way of managing permissions. When giving single members direct access to a collection or space, you override any inherited permissions they might have. Direct member access is great if you need very specific control over collaborators.
While this might seem pretty complex at first, GitBook's permission model gives you control if you need it, and gets out of the way if you don't. For many teams, a set-and-forget approach to permission management is all they need. For other teams, especially larger organizations, this level of control over access and workflow is essential.
If you just want to get your teammates onboarded and editing content with you, then you might never even need to look at permissions. Invite folks, set their default role, and any content you create will default to inheriting these roles. No need to get into the weeds!
For larger organizations, teams that split their organization up into discrete collections, or teams that need very granular control over workflow; then getting into the weeds is exactly what's needed. Using a combination of inheritance, overriding, direct team access and direct user access, you can create workflows and access models that keep you in control.
