Dave Raggett, one of the original developers of the HTML spec (and the one whose guide I first studied to learn HTML), and the original author of HTML Tidy, an HTML cleanup utility, has written a utility called HTML Slidy which is an outstanding tool for creating pure, XHTML standards-compliant & semantic web-based presentations.
His XTech 2006 presentation (warning: PDF file) provides a few more details as well as some information of a browser-based slide editor (not as interesting to me…). What is most excellent about Slidy is the fact that it uses the best practices of web design (standards compliance, semantics, & browser compatibility) to provide a truly intuitive web-base slide presentation tool. It’s usability cannot be overstated. Its features include:
I’m really looking forward to seeing this standard used more & more. Considering it is pretty much free from incompatibilities, I intend to start using it ASAP for any presentations I need to make. The best part is that, because it is based on XHTML Strict, it is also a valid XML document, and so it should easily losslessly convert to other media without too much difficulty, while also because pretty future proof. XML doesn’t seem to be fading out anytime soon.
