Context Participation
Participation items establish the following:
Roles that are automatically available in a context.
System groups that are automatically created in a context.
Product, library, project, and program contexts are associated with teams of users and user-defined groups. Any user can display all products, libraries, projects, or programs in which the user is identified as a team member. The users and user-defined groups in a team are associated with roles that identify the responsibilities and permissions of the team members. For example, the Product Manager role establishes who is in charge of the product; similarly, the Project Manager role establishes who is in charge of a project.
The set of roles and system groups that are automatically available in a context consist of the roles and system groups established in parent contexts, as well as those defined specifically for the context.
If the team established is in a context that includes a shared team, the shared team roles and system groups are defined and managed in the organization context where the shared team was created.
Installed Site Context Participation
Through the site context, roles and system groups that are useful throughout your Windchill solution are made available to the site.
Roles
The roles that are available to the entire site are defined in the <Windchill>\src\wt\project\RoleRB.rbinfo resource bundle, which is translated to all supported languages and made available through the application clients.
All of these role names are available to all child organizations and then to the product, library, project, and program contexts created within those organizations. To see the roles, navigate to Organizations > Roles. For products, libraries, projects, and programs, click the Team link under the corresponding context.
Groups
The following group is defined in the site context /System domain:
Administrators (known as the system or site administrators)
* 
This group defines the administrators for your entire site.
The following groups are defined in the site context /User/Unaffiliated domain:
Attribute Administrators
LifeCycleAdministrators
Type Administrators
Unrestricted Organizations
WorkflowAdministrators
These groups and any other groups established when your Windchill solution is installed are used during the normal operation of your Windchill solution and should not be removed. Domain-based access control rules can be automatically loaded in the site context /System domain granting permissions to members of these groups, except the Unrestricted Organizations group. The rules for the members of the Unrestricted Organizations group are loaded in the site context /User domain.
Editing Context Participation
Context participation is set by the template selected when the context is created. The roles defined in the template can be modified in the organization context as well as in an application context. Those roles defined in the organization are inherited by the child contexts of the organization.
From within an organization, use the Groups link to add or update user-defined groups and use the Roles link to add or remove roles from the organization.
From within a product, library, project, or program, use the Team link to add or remove roles. From the Members table, you also add and remove members from the roles. For additional information, see Teams.
