This use case describes the process a founder or co-founder will use to create a new group.
The diagram shows the requirements and rules the use case is responsible for (via the <<requirement>> stereotype).
The namespace for the group must have been registered previously.
The system has created the new group.
Requirements and rules realized
RQ8 Groups have a membership policy
A groups membership policy determines whether a player can join the group or not.
RQ26 Notify founder changes
The system shall notify a namespace founder of any changes according to rules: BR36
- BR36 New, re-named or deleted groups
The system shall notify the namespace founder when a new group has been created, an existing group re-named, or a group deleted from within the namespace.
RQ27 Group names unique
The system shall require a group name to be unique within its namespace.
- BR37 Group names are case insensitive
When determining whether a group name is unique, the system shall ignore the case of the characters, so that for example, COP and cop shall be treated as identical.
RQ23 Founders and co-founders assign group managers
The system shall prevent any player other than the namespace founder or co-founder, from creating groups or assigning group managers within that namespace.
