The N1 Service Provisioning System software includes a built-in category called system, which is automatically applied to internal resources. All other categories are user definable. As with naming conventions, careful planning should go into defining categories. When category naming conventions are well thought through they become powerful tools when used with searches and views to quickly identify or select groups of objects. Categories for each object are discussed in more detail in the sections relating to each particular object.
You can use categories to classify:
plans
components
resources
comparisons
