Permissions

Permissions in valispace are granular, and the overarching permissions start from the workspace level, then the project and flow through higher level objects in each module to all lower levels down to valis or requirements. The admin can alter the permissions on any level. When a new project is created within a workspace, by default, the project inherits the workspace permissions. By default, the workspace has “Everyone” has “Read & Write & Delete” Permissions. The admins can change the permissions of the objects in the permissions page within the project module. (refer to the Figure Permissions)

Permission Types

Permissions are cumulative, which means that higher-ranking permissions always automatically include all lower-ranking permissions. For example, “read” access is automatically included when you have “write” permission. The following four types are available (in cumulative order):

READ-ONLY

Read permission allows you to view a project and all its elements: components, Valis, and matrices. You can also use this data in other projects, for example in formulas of Valis. However, you cannot edit anything inside the project where you have “read” access.

READ & WRITE

To manipulate any elements inside a project you need to possess written permission for that project. With “write” permission, you can edit/delete the project and all components, Valis and matrices inside it. However, with written permission, you can't assign permissions for the project to other users.

Assigning the user with Read & Write permissions will not allow the user to delete the objects. For example, It allows you to create the objects however, deleting tags on a requirement or deleting a verification method or component cannot be done with this permission. If admins wanted to prevent accidental deletion of important specification, components, It is recommended to provide only “Read & Write” permission.

READ & WRITE & DELETE

This permission allows the user to have read and write permissions, as well as the possibility of deleting objects.

MANAGE

Manage permission for a project gives you the ability to add or remove permissions for other users for this specific project. You automatically get manage permissions for a project when you create it. A superuser can also assign manage permissions to you or remove them.

Special Permissions

Additionally to the project permissions, there are a few special permissions that are assigned on a user level:

Create/edit tags
Create/edit types

All of the above are granted by default but can be revoked by admins in the admin panel under “Users“ and going into the specific User Id.

Public Projects

In public projects, every user is automatically granted “write” permission. Projects are public by default and must be made private if permission management is required.

Superusers (Admin Rights)

Superusers by definition always have all available permissions. Superusers can also assign (and revoke) superuser rights to other users.

Setting up your Permissions

You can add custom permissions on each level within a module in Valispace. You can set permissions on workspace, project, and lower-level objects. If no custom permission is set, the user will inherit the permissions from the higher level in the order Workspace > Project > Components / Specifications > Subcomponents / Groups > Valis / Requirements.

You can add new permissions by clicking on the three dots ( More options) in the upper right corner and selecting Permissions.

In the side panel that opens you can set the permissions for the object that you have currently navigated to, or the project if you are in the project tab. At the top of the side panel, you will see the name of the object that you are setting permissions for, in the example below it's the Spacecraft_Spec. You can also see which object it inherits its permissions from if no custom permission is added. In this case the Spacecraft_Spec is inheriting its permission from the ValiSat project.

Custom Permissions

To add custom permission, click on Create Custom Permission on the side panel.

You will have two choices when creating new custom permission, which are explained below:

Inherit permissions from `object`

With this option, you can set custom permissions on object, which will also propagate to any children below it. The default custom permission for each user will be inherited from the parent object. Also, when creating new permission on the parent object, for example adding a new user to the project, its permission for the current object will be inherited from the parent. This is also the case when a user's permission in the parent object changes. If a user has a custom read permission and has to write permission on the parent, if the parent permission changes to manage, the read permission will be overwritten with the new manage permission.

Some example use cases are:

You want a user to have read access to a whole project, and custom write access to a specific specification and all requirements in that specification.
You want a user to have write access to a whole project, but only read access to a specific specification and all requirements in that specification.

Start permissions from scratch

With this option, all propagation of permissions from the parent level is stopped. There are by default no permissions created on the object, but you can add custom permissions for each user to this object. No permissions will be inherited from the parent, even when adding new users.
