Working with classes
You can define classes to create logical groups. 
    Classes can be used for searches and filtering queries. Classes are different from Set
      Classifications. Only a single value per object is allowed for an object class. Each object
      class is associated with an enumerated list. Some examples of object classes lists are:
    - Analysis Class (
C_ANALYSISCLASS) - Calendar Class (
C_CALENDARCLASS) - Company Class (
C_COMPANYCLASS) - Formula Class (
C_FORMULACLASS) - Global Calc Classes (
C_GLOBALCALCCLASS) - Label Content Class (
C_LABELCONTENTCLASS) - Ingredient Statement Rule Class (
C_LABELRULECLASS) - Project Class (
C_PROJECTCLASS) - Sample Class (
C_SAMPLECLASS) 
You can define the form layouts for different classes in the Configure Templates form when data field layouts require specific web templates.
