Mashups
• A new type of web applications.
• Combines data from more than one source into a single
integrated tool[2].
• Creating a new and distinct web service that was not
originally provided by either source.
• Content is typically sourced via an API* or a RSS Feed
Let’s see some examples..](https://image.slidesharecdn.com/jarrar-140129030622-phpapp01/85/Jarrar-Web-2-0-Data-Mashups-19-320.jpg)

- 32. Jarrar © 2013 32 Web 2.0 challenges Suppose you want to build a mashup: Build up your publications “publications webpage”, combining all data from all sources/APIs? • How to link data items cross sources? • How to answer structured queries (over different APIs) such as “Give me all people who works-at Birzeit and previously lived in Belgium”? • How to know the meaning/type of data Items? Bessan is a person name, or a city name? Linking data items cross sources, such that it becomes easy to integrate search, and retrieve (use RDF).
