Definition: A mashup is a web application that combines data from more than one source into an integrated experience. (WKP)
Content used in mashups is typically sourced from a third party via a public interface or API, although some in the community believe that only cases where private interfaces are not used count as mashups. Other methods of sourcing content for mashups include Web feeds (e.g. RSS or Atom), web services and Screen scraping. Many people are experimenting with mashups using Microsoft, Google, eBay, Amazon, Flickr, and Yahoo APIs, which has led to the creation of Mashup Editors.
