  15. 15. Jarrar © 2013 15 Web 2.0 Technologies Content syndication How can you deliver recent news to your users without forcing them to visit your website?  RSS, Atom Mashups How can you remix free content and make a new website? Web APIs (programmable web) How can make use of the free content inside my website? Companies are competing in gathering content from people and offering this content back through APIs (i.e. structured data)
  16. 16. Jarrar © 2013 16 Content Syndication Millions of online publishers including newspapers, commercial web sites and blogs now publish their latest news headlines, product offers or blog postings in standard format news feed[1]. A typical web feed logo
  17. 17. Jarrar © 2013 17 Content Syndication The two main families of web syndication formats are RSS and Atom.
  18. 18. Jarrar © 2013 18 Mashups / Programmable Web (The Puzzle of APIs)
  19. 19. Jarrar © 2013 19 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..
  20. 20. Jarrar © 2013 20 Mashups (Example) Real-time mashup of votes from around the world Ask500People.com

  31. 31. The Mashup Phenomena  From Web of Documents (Hypertext) into Web of Data In other words, The Web is becoming a Database, where a data source is seen as a table, and a mashup is seen a query over multiple tables/sources.  Data Web
  32. 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).
