Additional Resources

   

If you find this project useful, be sure you read Chapter 8 as well. Chapter 8 presents a different twist on the same technique and many useful extensions to the servlet.

DocBook

As has already been indicated, for more complex documents, you can turn to the DocBook DTD available from http://www.docbook.org. DocBook is a powerful DTD for document publishing and is available in both SGML and XML.

XHTML

WML is the most popular markup language for mobile users, but the W3C is working on its own solution. The W3C has developed XHTML, an XML version of HTML. The recommendation is available from http://www.w3.org/TR/xhtml1.

The major advantage of XHTML is that it is based on HTML so it will be familiar for Web designers. The major inconvenience of XHTML is also that it is based on HTML. This results in a large and complex markup language. Therefore, XHTML currently is too complex for mobile phones.

The W3C is working to simplify XHTML. Only time will tell whether XHTML will achieve widespread acceptance.

Open eBook

Another interesting format for mobile users is the Open eBook specification. Open eBook was designed for eBook, a different group of mobile users. An eBook can take many forms, but it is generally a palm- sized device on which readers download books.

You will find more information on Open eBook from the Open eBook Forum at http://www.openebook.org. A popular eBook reader is the Rocket eBook, available from http://www.rocketebook.com. Unfortunately, it does not support the Open eBook format yet.

ICE

I introduced RSS as the content syndication format in this chapter because RSS is very popular. RSS is not the only choice, however.

An alternative is ICE (Information Content and Exchange protocol). ICE is a more ambitious project that aims to link content providers and publishers. You can find more information on ICE at http://www.w3.org/TR/NOTE-ice.
