Hmm doesn't this sound like HTML5 may very well trail the development of 3.0? And i'm sure you're wondering the meaning and relevance to all of these?
Well HTML5 does play a vital role in the semantic web. If you remember my second article on which i spoke about the features, i mentioned ontology/meta data? Where by context are tagged with their characteristics like a ball, colour = "red" and type = "futsal".
And so, with HTML5, it provides support for Microdata. It's basically meta data for HTML elements / tags.
I'll use an example from briancray.com
The itemprop attribute is short for item property. By tagging the elements, the search engine will be able to infer that this message is associated to an event from "itemscope". Next, this big event is due to take place on the 4th of July (guessing you figured out the big event) at 6.00pm. So by tagging it with startDate and datetime this message now bears some understanding to a machine.
That example has been edited due to some space constraints, do checkout the site for the full example.
We can clearly see with this HTML5 feature, it has the potential to drive the development of Web 3.0. With the postponement of the finalization, i truly hope it doesn't keep websites and search engine developers from implementing them into their applications and sites sooner. Heck, they now have 3 more years to thinker around with it.
In your view, good or bad?
