An interesting baby-step in Google improving Search Results (man are they ever holding out on us!)
From Read/Write Web (Written by Marshall Kirkpatrick)
Did Google Just Expose Semantic Data in Search Results? Well did they? No. The results pages don’t expose any “structured data”
I really believe that Google is trying to avoid becoming everyone’s scrape-able Semantic Query Engine. There’s tons of at least semi-semantic data out there and google simply doesn’t present it to us. They have it. They understand it. They could give it to us. But they don’t. I mean for crying out loud, imagine how difficult it must be for google to return image search results that are anywhere near as good as google’s image results are? Does anyone really think that google is completely ignoring microformats or service-wide presentational semantic data (an example of this would be the html classes and ID’s assigned to elements on social network pages)?? Does anyone really think so? While they’re looking at things like alt tags and nofollow tags and everything else? Would google just ignore piles and piles of metadata? No. Would they decide to not let us use it? I think so.
I think they’re doing a classic ‘roll-out’ thing, saving their best search technology for when they absolutely have to whip it out for competitive reasons. This is cause to resent google to a certain extent I think.
