Access to a branch in Foundry Branching is primarily governed by two mechanisms: roles and organizations.
Roles control what actions a user can perform on a branch.
Each branch must have at least one Owner. The user who creates a branch is automatically assigned the Owner role, but the role may also be assigned. Owners have full control over the branch and can:
Administrators of the space that a branch belongs to have the same permissions as the Owner role.
Branch roles control access to branch management actions only and do not grant permissions to edit resources on the branch. To modify resources, a user must have the appropriate permissions at the project or resource level. To see resources on a branch or a proposal, you must be able to view that resource.
Roles can be managed by navigating to the Security tab on the branch page in the Foundry Branching application. Only owners and space administrators can modify role assignments.

In addition to role requirements, a user must be a member of at least one of the organizations listed on a branch in order to access it. Organizations act as an access gate to the branch itself. The organizations for a branch must be a subset of those associated with the space that the branch belongs to.
Avoid including sensitive information in branch names or other branch metadata as they may be visible on resources that have been added to the branch even if those resources are not protected by the same organization markings. For example, metadata such as the branch name may be visible on resources that have been added to the branch.
When creating a branch, choose a name that does not include sensitive information, as branch names may be visible outside the branch's organization restrictions.
The ontology selected at creation determines where you can make modifications on the branch. You cannot make changes outside the selected ontology, and the ontology cannot be changed after the branch has been created.
In most cases, no additional configuration is required — the branch will automatically be assigned to the space associated with the selected ontology. However, if you select the default ontology, you will need to manually select a space.
The space affects the branch in several ways:
Organizations determine which users can access the branch. You can select from the organizations associated with the chosen space. The default selection is determined as follows:
You can adjust the selection before completing branch creation.
