4. Taxonomy, ctd Your bookmarks, in your browser, also form a taxonomy.
In a taxonomy, each item has a unique set of descriptors.
For example, a human was a mammal, a type of animal, living, a part of the earth.

5. Folksonomies In a folksonomy, each item can be given several tags.
A human can be tagged as a mammal, a homo sapien, etc.
The term folksonomy refers to the tagging being collaborative, done by anyone in a community.
Folksonomy became popular around 2004 in several web applications.
Let's look at an application that can transform your bookmarks from a taxonomy to a folksonomy.
