Using extended attributes in the PDM

Chapter 3 DBMS Resource File Reference

Using extended attributes in the PDM

Extended attributes are used in a DBMS to control model generation.

You can also define extended attributes in an extended model definition, to further define an object. These extended attributes are not used during generation.

For more information on extended model definitions, see "Extended Model Definitions" in the Resource Files and the Public Metamodel chapter.

By default, extended attributes appear in the Extended Attributes tab, in a user-defined tab or in object lists.

Each extended attribute has the following properties:

Property	Description
Name	Name of extended attribute
Data type	Extended attribute data type including boolean, color, date, file, float, font, etc or customized data types
Value	Value of the extended attribute. This field displays the default value defined for the extended attribute data type
R	Redefined value. Selected if you modify the default value in the Value column, using either the arrow or the ellipsis button

The name and data type of the extended attributes can only be edited in the Resource Editor. The value can be modified in its property sheet.

To define the value of an extended attribute:

Open the property sheet of an object.

or

Select Model→Object to display a list of objects.

Click the Extended Attributes tab or the user-defined tab to display the corresponding tab.

or

Click the Customize Columns and Filter tool, select extended attributes in the list of columns, and click OK.

The extended attributes appear in different tabs or as additional columns in the list.

Click the Value column of an extended attribute if you want to modify its value and select a value from the list.

or

Type a value in the corresponding box.

or

Type or select a value in the value cell in the list.

The Ellipsis button allows you to further define the value of the selected extended attribute.

Click OK.
