How does Google keep on coming up with so many ingenious applications that amuse users, while simultaneously furthering their company's business ends. I think that Google Image Labeler is a great example of how metadata has become an intrinsic part of our daily online experiences, despite the fact that most people have never even heard the word metadata in their lives. Essentially, Google's search engines run on metadata, precisely what Image Labeler generates as it engages its Google users to participate in the creation of image labels (a type metadata) that can later be incorporated into their search engines as image labels .
At first, I was having some issues visualizing and understanding what metadata actually means. However, now I understand it to be the data about data. Metadata describes the particular characteristics of any given data (documents, pictures, songs, ect) - how it was collected, created and formated, when, and by whom. Metadata is crucial for understanding the information stored in data warehouses and is also an important component of XML-based web-applications.

Cool--part of the point of using the image labeler was to highlight both the idiosyncratic nature of the labeling process and also the fact that it has to be communal on some level to be validated.
