Great introduction to YQL (Yahoo Query Language), a query language for easily integrate APIs.

The Yahoo! Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services. With YQL, apps run faster with fewer lines of code and a smaller network footprint.

This small mashup uses YQL to combine the power of Flickr and Yahoo! Placemaker. Copy and paste some text into the textbox below and click the button — application will first geo-locate all places in the text, and then will try to find photographs, published under Creative Commons license, which were geotagged at or near found places.

interesting how Placemaker reacts differently to a text with "Rouen" and "at Rouen"

Yahoo! makes a lot of structured data available to developers, primarily through its web services. These services require developers to locate the right URLs for accessing them and the documentation for querying them. In contrast, the YQL platform provides a single endpoint service that enables developers to query, filter, and combine data across Yahoo! and beyond. YQL exposes a SQL-like SELECT syntax that that is both familiar to developers and expressive enough for getting the right data. Through the SHOW and DESC commands we enable developers to discover the available data sources and structure without opening another web browser.
