Audience

This chapter is intended for WebCenter Spaces users assigned, minimally, the Pages-Edit Pages permission who want to add content in a Content Presenter task flow to a page in a WebCenter Spaces application.

40.1 What You Should Know About the Content Presenter Task Flow

The Content Presenter task flow enables you to precisely customize the selection and presentation of content in a WebCenter Spaces application.

The Content Presenter task flow is available only when the connected content repository is Oracle Content Server and your WebCenter Spaces administrator has completed the prerequisite configuration.

40.1.1 Understanding Site Studio Integration

Oracle Site Studio is a powerful, flexible web development application suite that offers a comprehensive approach to designing, building, and maintaining enterprise-scale web sites. Site Studio uses Oracle Content Server as the main repository for a web site.

Site Studio region templates are defined in Site Studio Designer (or JDeveloper). They define the layout and look-and-feel of the data in contribution regions within web pages. They are partial HTML files in that they do not have a head and body section. At runtime, the Site Studio contributor data file (an Oracle Content Server document) is merged with the Site Studio region template to create the HTML fragment. This allows Site Studio region templates to be inserted into other HTML code as the web pages are generated for the Site Studio site.

Content Presenter integrates with Site Studio to allow you to create, access, edit, and display Site Studio contributor data files in either a Site Studio region template or a custom Content Presenter display template.

Note:

Before you can display Site Studio contributor data files in Content Presenter, the WebCenter application administrator must complete the followings tasks, described in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter:

Enable Site Studio components (SiteStudio, SiteStudioExternalApplications, as desribed in "Configuring Oracle Content Server 11g for All WebCenter Applications".
Disable or hide Site Asset categories that are not needed for typical Content Presenter implementations, as described in "Disabling Undesirable Site Asset Categories in Oracle Site Studio".
Enable the WebCenterConfigure component to allow for adding and editing Site Studio documents from within Content Presenter, as described in "What You Should Know About the WebCenterConfigure Component".

For proper surfacing in Content Presenter, the following link types can be used in both Site Studio region templates, as well as in a Site Studio contributor data file:

Link to nodes in the default navigation model, as described in Section 40.7, "Adding Links from Content to Navigation Nodes."
Links to inlined images.
Links to documents (except for absolute or relative path links). When clicking the link at runtime, it renders within the context of the application and display the document using the Default View display template.
Links to Site Studio sections when editing a WYSIWYG field in contribution mode and creating a server-side link.
Absolute HTTP links, whether created in Site Studio contributor mode or in Site Studio Designer region template HTML.

The following Site Studio link types are not supported in Content Presenter:

Links to Site Studio sections, except for the server-side link case listed above.
Absolute or relative path links to Site Studio documents.

For guidelines on authoring recommendations for displaying a Site Studio contributor data file in Content Presenter, see Section 40.8, "Authoring Site Studio Content to Optimize Presentation in Content Presenter".

You can create and edit Site Studio contributor data files from the Content Presenter Configuration dialog (see Section 40.9, "Creating or Editing Site Studio Content in the Content Presenter Configuration Dialog") or in-context when displayed in Content Presenter at runtime (see Section 40.10, "Creating and Editing Files In-Context in a Content Presenter Task Flow").

For more information about creating and using Site Studio contributor data files and Site Studio region templates, refer to the Oracle Site Studio documentation library.

40.2 Adding the Content Presenter Task Flow to a Page

To add a Content Presenter task flow to a page:

Open the page in edit mode.

See Also:
For more information, see Section 17.3.1, "Entering and Exiting Page Edit Mode."
Click Add Content in the target region to open the Resource Catalog.
Navigate to the section of the Resource Catalog that provides access to the folders and files in the connected content repository.

Tip:
The presence or location of this section depends on how the Resource Catalog is configured. For example, in the default Resource Catalog, next to Content Management, click Open to expose the content selections (Figure 40-1).
Next to Content Management, click Open (Figure 40-1).

Figure 40-1 Opening the Content Management Section in the Resource Catalog

For information about the selections shown in the default Resource Catalog, see Section 39.2, "What You Should Know About Content Management Selections in the Resource Catalog."
Add the Content Presenter task flow to the page in one of two ways:
- Next to Content Presenter, click Add (Figure 40-2).
  
  Figure 40-2 Adding a Content Presenter Task Flow to a Page
  
  A new empty region appears on your page (Figure 40-3).
  
  Figure 40-3 Adding a Content Presenter Task Flow to a Page
- Or, drill down in the Resource Catalog to the folder or file you want to display on the page: In the default Resource Catalog, next to All Content (or, in WebCenter Spaces, Space Documents or Personal Documents), click Open until you locate the target content, then click Add, and choose Content Presenter from the menu (Figure 40-4).
  
  Figure 40-4 Adding Content to a Content Presenter Task Flow

  Figure 40-6 Content Presenter Task Flow: Default Template for Image File

40.3 Displaying the Content Presenter Configuration Dialog

The Content Presenter Configuration dialog enables you to easily configure the Content Presenter task flow to select or change content, or choose a different display template.

Note:

You can also specify content and a display template by clicking the properties Edit icon (the second wrench icon in the task flow chrome) and specifying parameters on the Parameters tab of the Component Properties dialog. However, specifying parameters in this way is generally intended for use at design time by developers creating a WebCenter Portal application, or for advanced users who want to bind a parameter to an EL expression. If you modify a property value in the Component Properties dialog, the new value overrides the value specified in the Content Presenter Configuration dialog, and that value cannot subsequently be changed through the Content Presenter Configuration dialog. For information about Content Presenter task flow parameters, see Section 40.11, "Setting Content Presenter Task Flow Properties."

To display the Content Presenter Configuration dialog:

In the Content Presenter task flow (see Section 40.2, "Adding the Content Presenter Task Flow to a Page"), click the task flow Edit icon (the first wrench icon in the task flow chrome) (Figure 40-7).

Figure 40-7 Editing a Content Presenter Task Flow

The Content Presenter Configuration dialog opens (Figure 40-8).

Figure 40-16 Results of a Scenario Pane
Click Preview Query to see the results of the selected scenarios.

Note:
If the content repository includes an invalid type configuration, then no content displays when you click Preview Query. Instead, an error message reports Unable to retrieve content type information.
Any results that are returned from a scenario for use by Content Presenter must return a valid CMIS query, as Content Presenter takes the return value and runs it (as a CMIS query) against the repository specified within the Conductor URL. For information about how to format the query and examples, see Oracle Fusion Middleware Content Management REST Service Developer's Guide.

40.5 Selecting a Display Template

The display template for the content you have selected on the Content page of the Content Presenter Configuration dialog may be one of the out-of-the-box templates provided with WebCenter Spaces (see Table 40-2 and Table 40-3), a custom template designed for your organization in JDeveloper, or a Site Studio region template (see Section 40.1.1, "Understanding Site Studio Integration").

For information about creating and uploading custom display templates, see "Creating Custom Content Presenter Display Templates" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter. For information about creating and using Site Studio region templates, refer to the Oracle Site Studio documentation library.

By default, WebCenter Spaces selects an appropriate display template based on the type of content selected. You can change the default template as required.

The WebCenter Spaces administrator can show, hide, and manage the custom display templates on the Resources page of the application administration settings. For more information, see, Section 10.4, "Managing Resources."

To change the display template for the selected content:

In the Content Presenter Configuration dialog (see Section 40.3, "Displaying the Content Presenter Configuration Dialog"), click Select Template or the Template tab.

The templates that are available for selection in the Template list are those that are identified by Content Presenter as suitable for displaying the selected content item(s). For more information, see "Identifying Display Templates for Selected Content Items" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter.

On the Template page:

If the Content Source selected on the Content page is a Site Studio contributor data file or any other single content item, select a Site Studio region template or a Content Presenter display template, respectively, from the Template list.

The list of available Site Studio region templates includes only the templates that match the region definition of the Site Studio contributor data file selected on the Content page. To identify the Site Studio region templates, hover your mouse pointer over the templates in the list to display hint text identifying the Site Studio region templates. For more information, see Section 40.1.1, "Understanding Site Studio Integration."

The Content Presenter display templates in the list include the out-of-the-box templates for single content items (see Table 40-2). Other selections that may be available in the list are custom display templates that the application administrator has uploaded to your WebCenter Spaces application.

Figure 40-17 shows the Template list, with a Site Studio region template called PressReleaseFullDisplay selected.

Figure 40-17 Selecting the Custom Display Template

Description of "Figure 40-17 Selecting the Custom Display Template"
If the Content Source selected on the Content page is a multiple content item (Contents Under a Folder, Results of a Query, or List of Items), select the desired Template Category (Figure 40-18), then the Template (Figure 40-19).

Figure 40-18 Selecting the Template Category (for Multiple Content Items)

Figure 40-19 Selecting the Display Template (for Multiple Content Items)

By default, there is only one category: Default Templates. This selection defines the collection of out-of-the-box templates available for multiple content items (see Table 40-3).

Other selections that may be available are custom template categories and display templates that the application administrator has uploaded to your WebCenter Spaces application. For more information, see the "Creating Custom Content Presenter Display Templates" chapter in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter.

40.6 Previewing the Results

To see a preview of your selected content before adding it to the page:

Click Preview or the Preview tab.

The appearance of the content on the Preview page is dependent on whether the selected display template uses a stretch or flow layout. While the final view of the task flow can be configured to use either a stretch layout or a flow layout, the Preview page only uses a flow layout. As a result, the preview of content using templates that were designed for a stretch layout displays unstretched at a fixed default size. This is the normal behavior of stretchable content when displayed in non-stretching flow layout. To allow stretchable content to stretch to its full size and fill the task flow space entirely, click the Edit icon for the task flow to display the Component Properties dialog, and select the Stretch Content property (on the Display Options tab). For more information, see Section 17.5.2.5, "Working with Component Display Options."

Note:

From this tab, you can click Edit Web Content to edit HTML and Site Studio files in-context, as described in Section 40.10, "Creating and Editing Files In-Context in a Content Presenter Task Flow"

Figure 40-20 Previewing an Oracle Site Studio Contributor Data File

40.7 Adding Links from Content to Navigation Nodes

When you expose content stored in Oracle Content Server in a Content Presenter task flow, consider whether or not you want add one or more links from the content to a node in the default navigation model (see Section 11.2.2.1.8, "Setting Display Options for Navigation Items").

When the content displays in Content Presenter at runtime, an end user can click the links to navigate to the desired navigation model node.

You can create a link in the following content items in Oracle Content Server:

in a document of MIME type text/html (typically HTML files)
in a Site Studio contributor data file (in a Rich Text element)
in Site Studio region template

To add a link to a node in the default navigation model from a content item:

Edit the content item, as described in:
- Section 40.9, "Creating or Editing Site Studio Content in the Content Presenter Configuration Dialog"
- Section 40.10, "Creating and Editing Files In-Context in a Content Presenter Task Flow"
Add a link using the following syntax:
```
$wcUrl('externalId')
```
where externalId is the external identifier as configured in the WebCenter default navigation model.

For example:
```
<a target="" href="$wcUrl('NEWCUSTOMERSLINK')">New Customers</a>
```

40.8 Authoring Site Studio Content to Optimize Presentation in Content Presenter

Content Presenter integrates with Oracle Site Studio to allow you to create, access, edit, and display Site Studio contributor data files in either a Site Studio region template or a custom Content Presenter display template. For more information, see Section 40.1.1, "Understanding Site Studio Integration."

To optimize the presentation of Oracle Site Studio content in Content Presenter, follow the guidelines provided in the following sections:

Section 40.8.1, "Best Practices for Images"
Section 40.8.2, "Best Practices for Defining Styles"
Section 40.8.3, "Best Practices for JavaScript"

40.8.1 Best Practices for Images

Keep the following guidelines in mind as you work with images in Site Studio that will be displayed using Content Presenter:

Store images in Oracle Content Server in a common location (filed).
Insert images into WYSIWYG elements using the Site Studio Contributor image wizard.
Set the image tag src attribute to a relative link to an image file in Oracle Content Server. This attribute is rewritten by Content Presenter during rendering to use the GET_FILE service.
For performance improvement, use web proxy to cache artifacts at URLs from Oracle Content Server, and set expiration based on tolerance for updates in Oracle Content Server.

Example for Apache mod_cache:
- CacheEnable mem /cs
- CacheDefaultExpire 3600 (one hour)

40.8.2 Best Practices for Defining Styles

Keep the following guidelines in mind as you work with style definitions for Site Studio contributor data files that will be displayed using Content Presenter:

Define styles in CSS files.
Store CSS files either in Oracle Content Server or in your WebCenter portal application.
- If stored in Oracle Content Server, add <link> in <head> of page template.
Load style class names into WYSIWYG region element definitions.
Select your CSS to format HTML in WYSIWYG elements.
For performance improvement, use web proxy to cache artifacts at URLs from Oracle Content Server, and set expiration based on tolerance for updates in Oracle Content Server.

Example for Apache mod_cache:
- CacheEnable mem /cs
- CacheDefaultExpire 3600 (one hour)

40.8.3 Best Practices for JavaScript

Keep the following guidelines in mind as you work with JavaScript in Site Studio contributor data files that will be displayed using Content Presenter:

Recommended: Do not use JavaScript within web content that is rendered within WebCenter Portals.
If your web content uses JavaScript, follow these guidelines:
- Add <link> in <head> of page template
- For performance improvement, use web proxy to cache artifacts at URLs from Oracle Content Server, and set expiration based on tolerance for updates in Oracle Content Server.
  
  Example for Apache mod_cache:
  - CacheEnable mem /cs
  - CacheDefaultExpire 3600 (one hour)

40.9 Creating or Editing Site Studio Content in the Content Presenter Configuration Dialog

Note:

To create or edit Oracle Site Studio content in a seamless interface within WebCenter Spaces, both of the following two requirements must be met:

You must access the WebCenter Spaces application through Oracle HTTP Server (OHS) to expose Oracle Content Server and the WebCenter Spaces application under the same host and port. For information about setting up OHS as the frontend to WebCenter Spaces, see "Oracle Content Server - Configuration" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter.
WebCenter Spaces must be connected to an Oracle Content Server repository, with the webContextRoot parameter set to an OCS host name. For information on setting webContextRoot, see "Registering Content Repositories" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter. To set webContextRoot through WLST, see "createJCRContentServerConnection" and "setJCRContentServerConnection" in Oracle Fusion Middleware WebLogic Scripting Tool Command Reference.

Without this configuration, it is still possible to create or edit Site Studio content from within Content Presenter, but the create and edit actions launch new browser windows (or tabs) rather than opening within the Content Presenter task flow.

To create or edit Oracle Site Studio content from the Content Presenter Configuration dialog:

In the Content Presenter Configuration dialog (see Section 40.3, "Displaying the Content Presenter Configuration Dialog"), click Select Content or the Content tab.
On the Content page, click Create Web Content (Figure 40-21).

Figure 40-21 Selecting the Content Source: Site Studio

Tip:
The Create Web Content button displays only when the Content Source field displays Single Content Item and when at least one Oracle Content Server repository (11g or higher) has the Site Studio component installed.

The Oracle Site Studio Choose Region Content pane opens (Figure 40-22).

Figure 40-22 Adding Site Studio Content: Choose Region Content
In the Choose Region Content pane, select a Site Studio Region Definition on which the content you want to create or edit is based.

Figure 40-26 Adding Site Studio Content: Check-in Confirmation
In the Check-in Confirmation pane, choose one of the following:
- Edit content item now to open the Site Studio Contributor editor, where you can edit the content item as described in Section 40.10.2, "Editing Site Studio Files In-Context" (beginning with Step 4).
- Exit without editing to make no changes to the file.
Click Finish to return to the Content Presenter Configuration dialog.
- If you access the WebCenter Spaces application through Oracle HTTP Server (OHS) and have configured the webContextRoot parameter, as described in the Note at the top of this section, the Site Studio contributor data file you selected is shown auto-selected in the Content Presenter Configuration dialog.
- If OHS and the webContextRoot parameter are not configured, you can now select the Site Studio contributor data file to display in the Content Presenter task flow: On the Content page, browse to the Site Studio file, select it, and click Select.
In the Content Presenter Configuration dialog, click Save.

40.10 Creating and Editing Files In-Context in a Content Presenter Task Flow

In-context editing refers to editing content directly in a WebCenter Spaces application at runtime, where the editor opens in a separate window.

With appropriate permissions, end users can edit HTML and Site Studio content in-context in a Content Presenter task flow.

Note:

Users must have permissions to view and edit the page containing the Content Presenter instance, as well as being assigned a role with write permissions on Oracle Content Server.

40.10.3 Creating New Site Studio Content In-Context

With appropriate permissions, end users can create new web content in Site Studio when in in-context editing mode in a Content Presenter task flow.

In-context creation of Site Studio files is slightly different than creating Site Studio files in the Content Presenter Configuration dialog, as described in Section 40.9, "Creating or Editing Site Studio Content in the Content Presenter Configuration Dialog." When creating a new Site Studio file in-context, you are limited to creating content that is of the same region definition, file location, security group, and document type as the content selected in the Content Presenter task flow.

To create a new Site Studio file in a Content Presenter task flow:

Click anywhere in a Site Studio file that is displayed in Content Presenter and press Ctrl-Shift-C to enter the in-context edit mode. The editable areas of the web page are highlighted with a hashed border.
Click the Create icon, as shown in Figure 40-31.

To change the edit mode key sequence used to enter in-content editing mode for a Site Studio file in Content Presenter, edit the following entry in the application's adf-config.xml file:

******** Content Contributor Mode adf-config.xml entries ***************
 
<page-editor-config xmlns="http://xmlns.oracle.com/adf/pageeditor/config">
   <mode-switch-key>
      <enabled>true</enabled>
      <key-sequence>ctrl e</key-sequence>
   </mode-switch-key>
</page-editor-config>

40.11 Setting Content Presenter Task Flow Properties

The Content Presenter task flow has associated properties, which users with sufficient privileges can access through the Component Properties dialog in Oracle Composer (Figure 40-34).

Figure 40-34 Content Presenter Task Flow Component Properties

For information about accessing the Component Properties dialog, see Section 17.5.2.3, "Setting Component Properties."

The following sections provide information about properties of the Content Presenter task flow and describe the properties on the Parameters tab:

Section 40.11.1, "What You Should Know About the Content Presenter Task Flow Properties"
Section 40.11.2, "Content Presenter Task Flow Parameters"

40.11.1 What You Should Know About the Content Presenter Task Flow Properties

Note:

The Content Presenter properties are intended for use at design time by developers creating a WebCenter Portal application (see "Adding Content Task Flows and Document Components to a Portal Page" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter), or for advanced users who want to bind a parameter to an EL expression. If you modify a property value in the Component Properties dialog, the new value overrides the value specified in the Content Presenter Configuration dialog, and that value becomes read-only in the Content Presenter Configuration dialog.

The properties on the Parameters tab of the Component Properties dialog control the default task flow content. For descriptions of the parameters on this tab, see Section 40.11.2, "Content Presenter Task Flow Parameters" For some task flows, parameters on this tab facilitate the wiring of the task flow to page parameters and page definition variables. For more information, see Chapter 19, "Wiring Pages, Task Flows, Portlets, and UI Components."

Changes to the properties on the Display Options, Style, and Content Style tabs affect the appearance and behavior of the task flow for all users. These properties are common to all task flows. For more information, see Section 17.5.2.5, "Working with Component Display Options" and Section 17.5.2.7, "Working with Style and Content Style Properties."

The contents of the Events tab depend on the events supported by the task flow. For more information, see Section 17.5.2.8, "Working with Component Contextual Events."

All properties on the Parameters and Display Options tabs provide access to an Expression Language (EL) editor, which you can use to select or specify a variable value instead of a constant value. Click the Edit icon next to a property field to open the editor. For more information about using the editor and for descriptions of common EL expressions, see Appendix B, "Expression Language Expressions."

40.11.2 Content Presenter Task Flow Parameters

Table 40-4 describes the parameters that are unique to the Content Presenter task flow.

Table 40-4 Content Presenter Task Flow Parameters

Parameter	Description
`Data Source`	The data source of the content. The value depends on the value of `Data Source Type`: When `Data Source Type`=`Single Node`, set `Data Source` to a single node identifier in the format: `connection_name#dDocName:content_id` For example: `myconnection.us.oracle.com#dDocName:STAN_IDC-007619` When `Data Source Type`=`Folder Contents`, set `Data Source` to a single node identifier in the format: `connection_name#dCollectionID:collection_id` For example: `myconnection.us.oracle.com#dCollectionID:45535` When `Data Source Type`=`Query Expression`, set `Data Source` to a CMIS (Content Management Interoperability Services) query expression. Examples: `select * from cmis:document where cmis:name like \'test%\'` `connectionName=connection_name#select * from cmis:document where cmis:createdBy = \'weblogic\'` Note: If `connectionName` is not specified, then the primary connection will be used. For more information about how to format the query and for more examples, see Oracle Fusion Middleware Content Management REST Service Developer's Guide. When `Data Source Type`=`Multi Node`, set `Data Source` to a set of comma-delimited node identifiers in the format: `connection_name#dDocName:content_id`, `connection_name#dDocName:content_id`, ... For example: `myconn#dDocName:DOCUMENT_ID_12345,myconn#dDocName:DOCUMENT_ID_56789` When `Data Source Type`=`Scenario Results`, set `Data Source` to the results from a scenario in the format: `conductor-connection-name=conductor_conn_name,namespace=scenario_namespace,scenario-name=scenario_name,inputparm1=value1`,`inputparm2=value2,` ... For example: `conductor-connection-name=ConductorServiceLocal,namespace=CPNamespace,scenario-name=GetRelatedDocsScenario,topic=outdoors,interests=hiking` For information about the WebCenter Personalization Conductor and scenarios, see "Personalizing WebCenter Applications" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter.
`Data Source` (cont'd)	where: `connection_name` = the name of the content repository connection. `content_id` = the `Content ID` for the content specified on the content information page for the item in Oracle Content Server, or the `CollectionID` value on the content server. `collection_id` = the `dCollectionID` found in the URL for the folder information page in Oracle Content Server. `conductor_connection_name` = the name of the URL connection that points to the WebCenter Personalization Conductor (this name must start with `Conductor`). This value must match the `Reference name` attribute value in the `connections.xml` file for this URL connection. For more information, see "Configuring Content Presenter" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter and the appendix "Files for WebCenter Portal Application" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter. `namespace` = the name of the namespace that contains the specified scenario. `scenario_name` = the name of the scenario that Content Presenter will be using.
`Data Source Type`	The data source type of the content. Corresponds to the Content Source value in the Content Presenter Configuration dialog. Valid values are: `Single Node`: A single content item. `Folder Contents`: The contents of a folder. `Query Expression`: The results of a query. `Multi Node`: An ordered list of content items. `Scenario Results`: The results of the specified scenario created using the Scenario Editor in JDeveloper. See "Personalizing WebCenter Applications" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter.
`Maximum Results`	The maximum number of results to display when `Data Source Type` is `Query Expression`. Default: `100`
`Region Template`	Specifies whether the display template is a Site Studio region definition template. This value is valid only with Oracle Content Server 11g or higher: `${true}`: Display template is a Site Studio region definition template. The `TemplateView ID` value is used to select the region template. `${false}` (default): Display template is not a Site Studio region definition template. For information about creating and using Site Studio region templates, see Section 40.1.1, "Understanding Site Studio Integration" and the Oracle Site Studio documentation library.
`Task Flow Instance ID`	The unique identifier of this task flow instance, used internally to maintain the association of the task flow instance with its customization and personalization settings. Do not edit this value.
`Template Category ID`	The display template category ID to use in rendering results for multiple content items. This ID may reference one of the out-of-the-box display templates or a custom display template (see "Creating Content Presenter Display Templates" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter).
`Template View ID`	The display template view ID to use in rendering results for single content items. Enter the view ID of a template that is configured in the Resource Manager for a specific content type, or for list-based templates by category ID. This ID may reference one of the out-of-the-box display templates or a custom display template (see "Creating Content Presenter Display Templates" in Oracle Fusion Middleware Developer's Guide for Oracle WebCenter).
