About Creating XQuery Expressions with Design Studio

In general, the way you enter XQuery information into editors in Oracle Communications Design Studio is the same, regardless of the editor. The XQuery control in Oracle Communications Design Studio generally has three tabs: XQuery, Instances, and Information. Following are general instructions for entering XQuery information into each of these tabs in Design Studio.

Using the XQuery Tab

The XQuery tab allows you to configure XQuery-based rules or elements, or identify the source of the XQuery-based rules or elements. Select one of the following options:

Select None if the XQuery configuration is optional and not configured. When you select this option, Design Studio disables the remaining options in the subtabs.
Select Expression and enter the XQuery expression in the corresponding text box. Click Edit to open the Edit XQuery dialog box, which displays the configured XQuery expression in a larger and resizable text box. You can edit the expression in the Edit XQuery dialog box and click OK to save your changes, or click Cancel to dismiss the dialog box without saving the changes.

Note: Design Studio provides XQuery validation on basic syntax and semantics, and denotes errors with Problem markers.
Select File to denote that the XQuery configuration is located in a file saved to the project resources directory. This option enables you to write your XQuery expressions using any XQuery editing application you have installed in your Eclipse environment. See the Eclipse online Help topic Associating editors with file types for more information.

Click Select to open the Select XQuery File dialog box, which displays all XQuery files contained in the project resources directory. Select the appropriate XQuery file and click OK.
Select URI to denote that the XQuery configuration is located in a remote URI location. For example, you might enter:

http://osm_server/AIARecognitionRule.xqy

Click Properties to open the Properties view, where you can define the following information for the XQuery:

Annotation: The optional XML annotation element allows you to provide information about the XQuery. Enter information (for example, HTML-formatted information) for external systems into the Annotation <appinfo> field. Enter information for human users into the Annotation <documentation> field.
Language: When you work with multiple languages, you can select a different language for displaying the description and annotation. For more information, see "Defining Language Preferences" in Modeling OSM Processes Help.

Using the Instances Tab

You can define a Data Instance behavior to obtain data that is not included in the order data and make that data available to the rule. Click Add to add a Data Instance behavior. Select the Data Instance behavior and click Properties to configure the Data Instance behavior.

For more information, see "Defining Data Instance Behavior Properties" in Modeling OSM Processes Help.

Using the Information Tab

Use this tab if you want to describe the intended use of the rule. For example, you might describe the functionality of a complex rule or provide instructions on its use.
