Model XSD

You can model XML schemas at two levels, using UML Class diagrams that:

•	Have no XML schema-specific implementation details, to be generated directly by Enterprise Architect's Schema Generator; the generator applies a set of default mappings to convert the abstract model package to a W3C XML Schema (XSD) file

•	Are refined with XML schema-specific definitions using the XML Schema pages of the Diagram Toolbox, which provides the structures of the UML profile for XSD

In the Project Browser, create the top-level project structure you need (Model and Views), and click on the appropriate View.

Models

Views

Click on the New Package icon in the Project Browser toolbar. The New Model Package dialog displays.

Project Browser Toolbar

In the Name field type the name of the new package, and select the Automatically add new diagram and Open new diagram checkboxes.

Click on the OK button. The New Diagram dialog displays.

Add a Package

In the Name field type the name of the new diagram.

In the Select From panel select UML Structural, and in the Diagram Types panel select Class.

Add New Diagrams

Click on the OK button. The new Class diagram opens in the Diagram View, with the Class pages displaying in the Diagram Toolbox.

At this point you can either:

•	Create a Class diagram using the Class toolbox icons (click on the link to the right), or

•	Create a tailored XML Schema diagram using the XML Schema pages of the Diagram Toolbox (continue to step 6)

Diagram Toolbox

Class Toolbox

XML from Abstract Class Models

Click on the More tools option in the Toolbox and select Extended | XML Schema to display the XML Schema Toolbox pages.

XML Schema Toolbox

Click on the Schema icon from the Toolbox and drag it into the Class diagram.

The XSD schema Properties dialog displays.

Complete this dialog, and click on the OK button.

The New Diagram dialog displays.

Schema Package

Again, in the Name field type the name of the new diagram.

In the Select From panel select UML Structural, and in the Diagram Types panel select Class.

Click on the OK button.

An XSDschema stereotyped package is created in the Project Browser and on the diagram, with a child Class diagram.

Double-click on the Package on the diagram to open the child Class diagram, and use the constructs from the XML Schema Toolbox to model the XML Schema.
