Creation of Channels
The steps to be followed in creating a channel definition format are the following:
The contents of the channel should be determined.
The CDF file is written which contains the links to these contents.
A link should be placed in the web site's home page.
Some of the points that are to be considered while deciding the contents of a channel are the following :
A channel should not have more than eight items.
Channels should be arranged hierarchically.
A channel can contain sub channels.
4. The hierarchy of the channels should match the hierarchy of the web site for easy maintenance.
The next consideration is the ways in which the updated information about a channel is delivered to the end user. There are three different ways in which the user can obtain the updated information. In the first way the user can check in whenever he likes with the help of the channel bar. The second way is to notify the users through e mail and then load the channel whenever they like it. The third way is that the browser can periodically check the web site for updates and download the contents automatically.
