# Using the Property Editor of the Mapper

This section provides the following topics:

- Using the Property Editor When Editing an DTF File
- Using the Property Editor When Editing an XQ file

### Using the Property Editor When Editing an DTF File

While editing an DTF file in the Design View or the Source View, you can use the Property Editor to view or edit the properties of the selected method.

For example, if you select a XQuery transformation method in the Design View of a DTF file, you can change the name of the method by editing the name property in the Property Editor. You can also edit the annotations and attributes of the selected method in the Property Editor.

Note: Context Sensitive Help is available for the dtf annotations by selecting the annotation property or attribute in the Property Editor and clicking F1.

To learn more see Data Transformation Annotations.

### Using the Property Editor When Editing an XQ file

While editing an XQ file in the Design View, the Property Editor allows you to view schema properties about the nodes in the current map without opening the source and target XSD or MFL files. The Property Editor of the mapper displays a read-only view of the schema properties for the selected element(s). To change XML Schema properties you must edit the XSD file that contains the XML Schema. To change the schema properties for non-XML data, you must edit the corresponding MFL file.

Note: Selecting a link will select the target and source elements of the link. To deselect a link and the target and source nodes of the link, click an empty section of the middle pane (a section with no links) between the Source and Target panes of the mapper.

A selected target or source node is displayed with a gray or blue box around the node as shown in the following figure.

In the preceding figure, both customerName and name are selected elements, so the schema properties for both these elements will be displayed in the Property Editor.
