Is Common Tag alive even at Yahoo! ?
Here is a quote from Zemanta:
The underlying code for Balloons is open source and built on the Common Tag architecture, the open tagging format developed by Zemanta, Yahoo, AdaptiveBlue, Freebase, and others. It aims to make content more connected, discoverable, and engaging. As with Common Tag, every aspect of Balloons - from its open source code base to its use of Freebase's openly licensed content - has been designed to ensure the easy, free, and open spread of information across the web.Today AdaptiveBlue is the GetGlue social network for entertainment (where Apple plans to play with iTunes PING in iTunes 10.) Their code.google developer site has no page on Common Tag and I don't see it at their API page.
