Already existing HTML applications can be converted into WML applications for use on WAP-enabled devices, yet this process is not as simple as the alteration of the markup tags. This paper investigates the problems associated with the conversion process by examining the conversion of a functional information system that would be of benefit to its users when access from remote locations is required. This paper details a number of problems discovered with the conversion of complex HTML documents into simplified WML documents. The major problems of displaying tabulated data, hyperlinks, navigational aids, and user input are discussed, with possible solutions presented. The paper concludes by raising the issue of 'intelligent' automated HTML to WML conversion, a topic for future research.
