5. What is Mashup
• Idea for mashup is “combining data from two or more
sources and displaying in a unique way”
• In the context of web development, mashup is
 A web application to combine data, presentation or functionality
from two or more sources to create new services
 A second generation (Web 2.0) web application to aggregate
contents retrieved from external data sources to create an entirely
new and innovative service
 Few common examples:
• Google Maps for easy creation of Map mashup
• Flickr for creating picture/ image mashup
• WeatherBonk a weather mashup ( which combines Google
Maps, Weather Bug, national Weather Service)
• TELCO Mashup - OMELETTE
