This paper describes preliminary work in the uncovering of mashup patterns in order to find new directions for the design of mashup tools. We conducted a qualitative survey of high-quality mashups, as nominated in two popular mashup directories, and examined how the mashups made use of existing websites or improved upon them, how data from multiple websites were combined, and what kinds of user tasks these mashups might be suitable for. We describe a set of patterns what we found in our sample of mashups.
