1.3.2.4. Palm Web Clipping

Web Clipping is a technique by Palm Computing. A Web Clipping application is a kind of small web site or special kind of record database that resides on the Palm organizer. A typical application contains an HTML form or list of hyperlinks that request additional information either locally - on the handheld computer - or remotely - on the Internet. A Web Clipping application is authored in a subset of HTML 3.2 including hyperlinks, forms and graphics. It is then compiled with the Web Clipping Application Builder. This compiled application needs to be installed on a Palm organizer like any other Palm application. The Web Clipping application itself runs inside the Web Clipping Application Viewer in the Palm organizer. When tapped, the pages and graphics of the application are rendered on the screen of the Palm organizer by the Web Clipping Application Viewer.

A Web Clipping is a results page requested by a Web Clipping application to a WWW server. Web Clippings are typically small HTML pages generated by a web application from the user's query, though they can be static pages on a WWW server as well. The query is sent from the Web Clipping application to the Palm Web Clipping proxy servers of the Palm.Net service. From there, the query is sent on to the appropriate WWW server over the Internet. The HTML results page - the Web Clipping - retraces these steps to arrive at the user's Web Clipping application where it is rendered.

The Basic Palm.Net plan allows for the transmission of 50 KB per month; the Expanded plan allows for 150 KB per month, and the Volume plan for 300 KB per month. Each byte up and down counts! This means that the user cannot request any amount of Web Clippings. Therefore, the Web Clipping content providers and application developers should consider this limitation. [7]
