This talk was given by Mark Birbeck at 'Kings of Code', in Amsterdam on May 27th, 2008. The W3C has a number of exciting new languages in development, from XForms for user interface definition, to RDFa and @role for defining semantics. These languages are usually regarded as something to be implemented natively by browsers, but this presentation shows examples of how they can also provide a rich source of 'hooks' onto which to attach 'unobtrusive javascript'.

1. The future of web languages Mark Birbeck http://webBackplane.com/mark-birbeck

2. Standards "The nice thing about standards is that there are so many of them to choose from." -- Andrew S Tanenbaum

3. Agile

4. Modular

5. Semantic

6. Use high-level languages to bind functionality

7. RDFa

20. Improving search

25. Improve user experience

26. Examples using RDFa

27. @role

28. <ul role=&quot;navigation&quot; > <li>Home</li> <li>Customers</li> <li>About Us</li> </ul>

29. Web languages as programming languages

30. XForms

31. <xf:trigger> <xf:label>Send</xf:label> <xf:action ev:event=&quot;DOMActivate&quot;> <xf:message level=&quot;modeless&quot;> Your email has been sent. </xf:message> </xf:action> </xf:trigger>

32. <div> Send <xf:action ev:event=&quot;click&quot;> <xf:message level=&quot;modeless&quot;> Your email has been sent. </xf:message> </xf:action> </div>

33. XML Events

34. <div> Send <xf:action ev:event=&quot;click&quot;> <xf:message level=&quot;modeless&quot;> Your email has been sent. </xf:message> </xf:action> </div>

35. SMIL

36. <xf:trigger> <xf:label>Animate</xf:label> <xf:action ev:event=&quot;DOMActivate&quot;> <smil:animate targetElement=&quot;panel&quot; attributeName=&quot;width&quot; to=&quot;200&quot; dur=&quot;3&quot; repeatCount=&quot;indefinite&quot;></smil:animate> <smil:set attributeName=&quot;display&quot; targetElement=&quot;hidden&quot; to=&quot;block&quot; fill=&quot;freeze&quot;></smil:set> </xf:action> </xf:trigger>

37. Examples using XForms, XML Events, and SMIL

38. The Ubiquity Library

39. Summary Smarter mark-up languages make programming web apps easier (and portable)
