♦ A type name cannot have the same name as another type on the same level in
the same type tree.
A type name may be up to 256 characters in length, but use a short type name if
possible. The full path name of each type is used in map rules in the Map
Designer. Refer to the Description to remember what the type represents.
Class
The class of a type describes whether the type represents a simple data object
(item), a complex data object (group), or whether is used to organize types
(category). Define the class of the selected type by selecting the class from the
drop-down list in the Value column.
Property Description
Category A category type is represented by a red icon ( ) next to the type
name in the type tree. Categories organize types that have
common properties. Each category has a set of item properties
and a set of group properties. Subtypes of the category inherit
these properties.
A category does not define data objects in detail and it does not
represent data to be used in a map. You never map a category
type, so a category type does have components. A category type
may be a component of a partitioned group, after a component
with the identifier attribute. A category cannot be a component of
a non-partitioned group.
Group
A group type is represented by a green icon ( , , and ) next
to the type name in the type tree. Groups with a Group
Subclass of Sequence display the group icon. Groups with a
Group Subclass of Choice display the group icon. Groups
with a Group Subclass of Unordered display the group icon.
The group type represents a complex data object that consists of
components.
Item An item type is represented by a blue icon (
) next to the type
name in the type tree.
The item type represents a simple data object that does not
consist of any objects. An item does not have components.
To change a type’s class, select the type and choose the desired class for the
Class property in the Properties window.
