What is Tagging?

You’ve likely been hearing quite a bit about tagging lately. If you’re not sure what that actually is, here’s a great article that gives a wonderful overview.

Tagging is a non-hierarchal (for hierarchies think of the old Yahoo! directories) means of organizing information or objects on the web. Information is found through associative correlations or inference. In a hierarchy one would go to people, then film, and then actress to find Cate Blanchett. Using tagging one could use actress and moviestar to get a similar result. Prior to computing hierarchies were an efficient means of organizing information. With computing we have more options, which can work just as well.
