HTML5 gives developer interesting capabilities to work with. What I consider most important is to store data locally – this enables developers to create apps that store quite complex data. Albeit possible in the past – cookies – the data storage capabilities were limited and required a considerable amount of additional work.
With HTML5, the Web moves actually towards the original vision of the internet: a hypertext system where every one of us can change or make annotations of web pages that one has visited. With HTML5 there is no additional overhead to store user names on the web server and manage the data there. All is stored in your own browser locally. The drawback of such an approach is certainly that if you re-install your browser, your content will be lost. This is the reason why I posted a Praktikum offer at the Distributed Systems Group at Vienna Technical University. Whoever is willing to do this for credits, the outcome will be something very useful – Web Page Stickers in HTML5. I’ll keep you posted about the developments and then we might be able to answer the question, whether HTML5 is the future of active Web pages, or something completely different
