ABSTRACT Recently, wireless terminal users that want to a gain various information from www have been increased rapidly. Already-existing HTML applications can be converted into WML (Wireless Markup Language) applications for user on WAP (Wireless application Protocol) enabled devices[10], 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 derails a number of problems discovered with the conversion of complex HTML[5] documents into simplified WML documents[4]. The major problems of displaying tabulated data, hyperlinks, navigational aids and user input are discussed, and described with possible solutions presented. The paper concludes by raising the issue of ¡¥intelligent¡¦ automated HTML-to-WML conversion, a topic for future research.

In this project multi-presentational e-commerce solution prototype (e-shop) was designed and implemented. It has capabilities of working on multiple presentation areas simultaneously, including areas where very limited presentation capabilities are present, for example WAP/WML. Solution prototype is accessible via different devices – desktop, palm computers, and even low-end cellular phones. Additionally, WAP protocol and problem domain research was accomplished, and possible e-commerce solution adoption methodology for WAP scene was presented. In brief, following results were achieved: 1. Proved that it is possible to transform average-complexity e-commerce solutions from Web into low-capability wireless devices, using WAP/WML technologies (although some complex functionality might be lost) 2. Web e-commerce solution adoption methodology for WAP scene was introduced, including: - list of possible architectures for bringing solutions from Web to wireless - including pros and cons of each architecture - expandable rules for converting HTML to WML 3. Multi-presentational e-commerce solution prototype was created.

<p>The Center for Genomics and Bioinformatics (CGB) is an academic department at Karolinska Institute. Generally stated, the CGB department is committed to the generation and management of genetic information by approaches aiming at elucidating the connection between genes, protein and function.</p><p>WiGID is a genome information database that is available through WAP (Wireless Application Protocol).</p><p>Our version of WiGID is based on WML, PHP and PostgreSQL as a database server.</p><p>One of the changes on the old WiGID application was the creation of a relational database with seven tables and one view, instead of the file that represented the database on the old version. We also changed the script language from python to PHP.</p><p>The search engine ability has been extended with three new search alternatives for a user to choose from. Each choice leads to other, sometimes multiple choices.</p><p>A GUI has been created for the administrator, to be able to insert information into the database.</p><p>The structure of the search engine is primarily for narrowing down the search result on the phone display, thereby making the search efficient.</p> / <p>Wireless Genome Information Database (WiGID), är en genome information databas och är tillgänglig genom WAP (Wireless Application Protocol).</p><p>WiGID har vidareutvecklats med WML och PHP som skript språk istället för WML och Python.</p><p>Några exempel på den ny utvecklade WiGID är navigationsmöjligheterna och applikationens bakomliggande struktur.</p><p>Modelleringen av relationsbaserade databasen har gett ökad flexibilitet till applikationen. Den är inte längre statisk och svårhanterlig. Hanteringen av databasen har lösts genom inmatnings skriptet. Inmatnings skriptet hanterar information från en fil som den läser ifrån och lägger informationen i respektive tabell.</p><p>Sökmöjligheterna har ökats genom användning av SQL (Structured Query Language). Navigationsmöjligheterna i sökmotorn utökades till sex valmöjligheter istället för tre enligt den äldre versionen. Varje länk går vidare till nya alternativ för att förfina själva sökningen. Sökningen har effektiviserats och valmöjligheterna.</p>

Gemeinsamer Workshop von Universitaetsrechenzentrum und Professur "Rechnernetze und verteilte Systeme" der Fakultaet fuer Informatik der TU Chemnitz. Workshop-Thema: Mobilitaet Dieser Vortrag vermittelt eine Uebersicht zu den derzeit verwendeten Technologien, um Inhalte auf mobilen Endgeraeten darzustellen. Speziell geht es dabei um vergleichende Betrachtungen zwischen WAP (WML) und i-Mode (cHTML). Ferner werden potentielle Entwicklungsmoeglichkeiten unter dem Einfluss von XHTML Basic, XML und XSL aufgezeigt.
