> ## XML schema Mapping Tool

> Every time the SmartB2BObject converts some document to or from XML, it must read the logical associations from a map file. You or the user of your application must create each such map file specifically for a particular document schema and direction (inbound or outbound). This can be a non-trivial programming task. Progress Software provides an editor—the XML Mapping Tool— to make that task easier.

> Figure 6–4 shows the Mapping Tool’s window.

> Figure 6–4: XML Mapping Tool window

> The Mapping Tool window is divided into two spaces—a tree view on the left and a tab control with four tabs on the right.

> The tree view displays the current state of the map file. Each line represents a mappable element of the document. As you make mapping choices, the tree view changes to reflect them. When every node displays a mapping, your map file is complete.

> The four tabs on the right contain the editing interface:

> - The Map tab is where you will do most of the mapping work.

> - The Schema tab provides read-only information about the current schema file.

> - The Source tab offers a read-only view of the raw schema source.

> - The Object tab allows you to identify the local SmartObjects to use when mapping nodes.
