What’s a “mashup?”
See http://www.chicagocrime.org/ . This is an example of how social scientific data can be combined in a web page using other software too. This site uses Google Earth and html to map out crime for all the street corners of Chicago!
By definition, a mashup is a web site that combines the use of software. Well, that is one definition. Essentially it is when information and presentation are separated and then put back together in ways that allow for novel forms of reuse and analysis not possible in its original form. It is not limited to social science data of course, but its important that you know that social science data is ripe for this type of application.
