If you've ever used tagging to bookmark or organize content, you know that there can be many different tags associated with a variety of terms and topics. Mustang could be a tag for a car or a horse. Columbus is a city but also a historical figure. Los Angeles could be tagged as la or los_angeles.
Now, Yahoo!, Zemanta, AdaptiveBlue, DERI (NUI Galway), Faviki, Freebase and Zigtag have collaborated to develop a semantic tagging format in the hopes of unifying the tagging process. Dubbed Common Tag, the format is an open tag with metadata and unique URLs.
"Semantic tagging is an important next step in the evolution of the Web. When we add semantic meaning to tags, the content that is tagged becomes significantly easier for machines to understand," said Peter Mika from Yahoo! Research. "That in turn allows for the development of more intelligent applications for aggregating, searching, and browsing the Web."
The idea is that over time, more and more websites and internet companies embrace Common Tag. Ultimately, content discovered through Common Tags could be used in application development, furthering and streamlining the distribution of published content on the web.
