Yahoo! Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web. It’s a service that generalizes the idea of the mashup, providing a drag and drop editor that allows you to connect internet data sources, process them, and redirect the output.
Like Unix pipes, simple commands can be combined together to create output that meets your needs:
- combine many feeds into one, then sort, filter and translate it.
- geocode your favorite feeds and browse the items on an interactive map.
- power widgets/badges on your web site.
- grab the output of any Pipes as RSS, JSON, KML, and other formats.
