Open Your Data Up to Bots Using Microdata

Microdata is another technology that’s rapidly gaining adoption and support, but, unlike WAI-ARIA, it’s technically part of HTML5. Although still early in development, it’s worth mentioning the Microdata specification here, because the technology provides a peek into what may be the future of document readability and semantics.

In the spec, Microdata is defined as a mechanism that “allows machine-readable data to be embedded in HTML documents in an easy-to-write manner, with an unambiguous parsing model.”

With Microdata, page authors can add specific labels to HTML elements, annotating them so that they can be read by machines or bots. This is done by means of a customized vocabulary. For example, you might want a script or other third-party service to be able to access your pages and interact with specific elements on the page in a certain manner. With Microdata, you can extend existing semantic elements (such as article and figure) to allow those services to have specialized access to the annotated content.

This can appear confusing, so let’s think about a real-world example. Let’s say your site includes reviews of movies. You might have each review in an article element, with a number of stars or a percentage score for your review. But when a machine comes along, such as Google’s search spider, it has no way of knowing which part of your content is the actual review—all it sees is a bunch of text on the page.

Why would a machine want to know what you thought of a movie? It’s worth considering that Google has started displaying richer information in its search results pages, in order to provide searchers with more than just textual matches for their queries. It does this by reading the review information encoded into those sites’ pages using Microdata or other similar technologies. An example of movie review information is shown below.

Editorial: Which Planet of the Apps Are We On?

If you haven’t heard that Apple is launching a TV show about app-making, then, I wonder… which planet you’re living on? The trailer for the new show promises the following: In every episode, app developers work to earn millions of dollars in venture capital investment. It begins with a pitch to four of the world’s most culturally influential entrepreneurs. […]. It all leads to a final pitch with one of the hottest venture capital firms on the planet. The developer community’s reception, so far, has been negative. Rock Star Developer and maker of Instaper Marco Arment tweeted: I’m sure Planet of the Apps will be a great show for all of those people who bug developers with their awful ideas. But actual developers… Well, this likely has about as much relevance to reality as most “reality” shows. Aside from the fact that judging a show purely by its trailer is, shall we say, unwordly, I say: Think different, content-creation is an avenue that Apple has much exploration to do in, and they have the resources required for it (visibility, money, domain knowledge, and talent). Consider this an experiment. Worst case scenario; mobile apps gain more visibility. Best case scenario? The perceived value of apps and your job becomes higher. You’d be automatically promoted from Rock Star to Rock Legend.
