Today on the “Official Google Maps API Blog” Google announced that they will use the hcard microformat in Google maps to markup address information.
“Today we’re happy to announce that we are adding support for the hCard microformat to Google Maps results. Why should you care about some invisible changes to our HTML? By marking up our results with the hCard microformat, your browser can easily recognize the address and contact information in the page, and help you transfer it to an addressbook or phone more easily.”
There’s a lot more that they could do along these lines if they went with RDF and/or RDFa. I wonder what the three best ideas are? Maybe we could collectively work up a good list and interest some Google researchers in using their 20% research time to play with the ideas.
