Using CDF Protocol

Channel Definition Format (CDF) is a technology used to create a channel on the internet, and is built with a specific protocol. Channels use a push technology, making information immediately available to the consumer. This is good for both the owner of the content and the person who needs it. Thus, when the technology was invented with the release of Windows 4, it became an important aspect in building pages on the web.

In contrast, pull technology is what you’ll normally find on the web. This requires the consumer to consciously search out your page. When you create a channel using CDF protocol, you utilize the push technology. This can allow your consumers to subscribe to your channel and have the information instantaneously, giving your page an immediate outlet to the people who are interested. By putting the information in their hands, it removes the effort needed on their part.

To begin creating your channel, you’ll need to know the basic information. What will the name of your channel be? What pages will be included? How often will you update it? Once this is decided you can begin building your page in basic HTML. From there you’ll need to outline it with XML. In order to do this it is suggested to use a text editor. Symbolclick.com offers a basic XML editor. This is easy to use and a useful resource.

When building the XML you’ll need to include information such as the start date of your channel, a brief description that will be seen on your page and the XML version you’re using. Most importantly you’ll need to specify how often you want your channel to be updated.

To complete these steps you’ll need to have basic knowledge of XML. For specific XML examples and directions, read through the About.com, Web Design/HTML article detailing the language used.

It is important to note that this technology was created when Windows 4 was released, and is applicable only if you still use Windows 4 – Windows 6. When Windows 7 was made available, this CDF protocol became obsolete. However, many people still use older versions of Windows, thus the use of this technology is still very relevant.

Using the web to its full potential is becoming more possible with every new discovery. Knowing CDF protocol is a useful way to get your content to the consumer that is fast and easy for them.
