Concept and challenges Channels and devices Channels and devices Restrictions and variationsPersonalization Contents are designed—personalized—on-the-fly for each user or user group based on their preferences. The contents are not the same for all users or business partners.Adaptivity The contents and presentation can "adapt" to the device/display the user has for browsing (also network capacity etc.)Content-awareness Based on user's location, preferences, time, usage history, etc., the user gets the "best-matching" contents and presentation available People do not always want that they are monitored Kari Aaltonen  Much more than XML only!!!

Why do we need XML HTML is the most successful markup language. You can view the simplest HTML tags on virtually any device, from palmtops to mainframes, and you can even convert HTML markup into voice and other formats with the right tools. Given the success of HTML, why did the W3C create XML? Mr. Matti Möttönen Sivukatu Espoo The trouble with HTML is that it was designed with humans in mind. Even without viewing the above HTML document in a browser, one can figure out that it is someone's address. You and I know it's an address, but a machine doesn't. As humans, you and I have the intelligence to understand the meaning and intent of most documents. A machine, unfortunately, can't do that. While the tags in this document tell a browser how to display this information, the tags don't tell the browser what the information is. You and I know it's an address, but a machine doesn't.

XML simplifies data interchange Because different organizations (or even different parts of the same organization) rarely standardize on a single set of tools, it can take a significant amount of work for applications to communicate. Using XML, each group creates a single utility that transforms their internal data formats into XML and vice versa. Best of all, there's a good chance that their software vendors already provide tools to transform their database records (or LDAP directories, or purchase orders, and so forth) to and from XML. Kari Aaltonen

XML enables smart code Because XML documents can be structured to identify every important piece of information (as well as the relationships between the pieces), it's possible to write code that can process those XML documents without human intervention. The fact that software vendors have spent massive amounts of time and money building XML development tools means writing that code is a relatively simple process. Kari Aaltonen

XML enables smart searches Although search engines have improved steadily over the years, it's still quite common to get erroneous results from a search. If you're searching HTML pages for someone named "Kake," you might also find pages on chocolate chips, computer chips, wood chips, and lots of other useless matches. Searching XML documents for elements that contained the text Kake would give you a much better set of results. Kari Aaltonen

XML makes more metadata Semantic Web: metadata and intelligence to the Web Metadata Metadata like RDF (Resource Description Framework) to better describe the contents and relationships of your data. Kari Aaltonen
