Unwired Accelerator uses a one-click content capture technology that allows you to create applications from Web-accessible sources.
The one-click capture strategy allows you to target a specific area on a Web page from which to capture content using links to navigate to the page that has the information from which you want to create an application. The content capture technology allows you to select only those pieces of information that you want to use in an application.
You cannot always navigate to every possible page and successfully create applications from all Web accessible sources. You may not be able to navigate to some sites or pages within sites. You also may not be able to create an application using the exact piece of information that is viewable to the user on a Web page. Web sites that use JavaScript to generate some or all of an HTML page, and sites that use frame-based solutions are especially challenging. UA provides several options you can try singly or in combination to overcome these challenges. See “Guidelines for choosing capture options”.
Once you create an application using a Web-accessible source, the application retrieves the current information from the source. If the layout of the information on the original page changes, the underlying technology attempts to locate the correct piece of information that represents the application’s content. However, if the application loses its content or obtains an incorrect piece of information because of changes in the source site, the application must be re-created.
Web elements do not store static HTML, but instead are defined by a code conversion language (CCL) statement that dynamically retrieves the content from its source. The CCL statement consists of:
The location of the Web page, and
The feature tag of the captured content. This feature tag is an electronic signature of the content and consists of a feature list that describes the content.
When Mobile Web Studio executes the CCL statement, the capture technology parses the Web page and returns the piece of content that matches the feature tag. If an exact match cannot be determined, the content with the closest matching feature tag is returned. This allows Mobile Web Studio to render the correct Web element even though the content, location, or formatting of the source may have changed.
