Yahoo! says that Common Tag makes “web content more discoverable” and enables the community to “create more useful applications for aggregating, searching, and browsing the web.” Their blog post mentions that they want to accelerate the structuring of the web, which aligns with their SearchMonkey launch last year, which they said was, in part, an attempt to encourage the use of structured data on the web. This brings to mind a few questions.
Why did the web need a new semantic standard? The Common Tag blog explains:
“Semantic web promises havens. The promise of machines understanding the data and acting on it semi-autonomously. But how do we get there? Not many are willing to put in a lot of work into publishing data in new formats. For the benefit that might or might not come years after enormous resources will be spent?
So why not start with something easy, say tagging? Marking up text with exactly defined concepts. “
