Taxonomy of social networking data

Here is a list of taxonomy of social netowokring data that is useful:

Service data is the data you give to a social networking site so that it is used. Data like this might include your legal name, your age, and your credit-card number.

Disclosed data is what you post on your own pages: blogs, pis, messages,  opinions etc.

Entrusted data is what you post on other people’s pages/sites. It basically means the same as disclosed data, but the difference is that you don’t have control over the data once you post it — the other user does.

Incidental data is what other people post about you: a writeup by someone about you, a picture of you that someone else clicks and posts. Again, it’s basically the same as disclosed data, but the difference is that you don’t have control over it, and you didn’t create it in the first place.

Behavioral data is data the site collects about your habits by recording what you do and who you do it with. It might include games you play, topics you write about, news articles you access (and what that says about your political leanings), and so on.

Derived data is data about you that is derived from all the other data. For example, if 80 percent of your friends self-identify as gay, you’re likely gay yourself.”
