Do it your way with execute and open data tables

Filed under feature

Today we’ve released a significant new feature for YQL: <execute>.

Previously our open data tables enabled any developer to bring the power of YQL and the table model available to new APIs or data sources that we hadn’t covered. Many of these are hosted on github, and you can read (and use) about them on These give you access to friendfeed, google reader, guardian, lastfm, nyt, twitter,, whitepages, yelp, zillow to name just a few.

YQL <execute> extends the open data table capabilities through server-side transformation and processing using javascript. This dramatically increases the reach and power of open data tables, for example:

  • join data across services
    e.g. grab New York Times article tags and incorporate associated flickr photos
  • combine multiple searches into a single result
    twitter, web, news and image…
  • augment data
    e.g. Add city/state information to APIs that just return zip code
  • create an API from a web page
    e.g. celebrity birthdays scraped from imdb
  • access APIs that require authentication
    e.g. Netflix OAuth, FlickrAuth, Google AuthSub …
  • data transformation
    e.g. convert the result from xml to Google’s kml format
  • move business logic for your application’s data to the cloud
  • leverage the work of others to make access easier by sharing tables

Read more about this on our YDN blog post, including links to several examples to wet your appetite.
