This topic defines a group and how it functions within Location Awareness Services for WebSphere® Premises Server.
Groups are containers that allow grouping of items from different classes for common rules, searches, or so forth. For example, the Fire Brigade group can contain fire fighters (persons) and fire extinguishers (assets). Such containers are often referred to as views because you can view the items from a distinct perspective.
An item can belong to one or more groups; however, it does not have to belong to a group. A group can be a member of one or more groups; however, it does not have to be a member of another group.
You can specify that a group hierarchy be used by setting the HierarchicalGroups property in System Properties. The default value for HierarchicalGroups property is Yes, meaning group hierarchy is used.
You can select a group color in the Group Manager portlet if the HierarchicalGroups property is set to true. The color then displays behind all group member icons on the Spatial Management Client.
