Enterprise taxonomy and ontology initiatives are collaborative exercises often involving numerous stakeholders with different roles and responsibilities. Graphite has a permission model that supports precise control of what different stakeholders can see and what editorial permissions they have.

Users come together to collaborate in a Graphite Project. A Project is a container of one or more taxonomy schemes, users and user-permissions.

Graphite allows role-based user groups to be defined with specific permissions granted to perform whatever tasks each group requires. Following are generic examples.

• Observer – read-only access to search, browse and view one or more schemes
• Commenter – view access to one or more schemes and the ability to edit designated fields, such as ‘SME Comments’ and ‘SME Approved’
• Editor – read-write access to create, edit and delete candidate concepts and their properties and relationships
• Mapper – permission to make mapping relationships between schemes but not to make editorial changes to schemes themselves
• Approver – permission to promote candidate concepts to be Approved or Published or to Reject or Withdraw concepts
• Project Admin – ability to create, version or change the design of schemes and user permissions within a designated Project
• Super Admin – ability to create, version or change the design of any scheme and any user permissions across the system
