Through additional user interfaces:

search APIs and tools

Yahoo provides search APIs like:

BOSS

  • Yahoo Search BOSS
    • When calling the BOSS web search API, you can retrieve all structured data Yahoo! has extracted for the specified URLs via SearchMonkey, including any microformats. Just add the parameters "view=searchmonkey_feed&format=xml" to your web search API call. This is probably the most efficient way to fetch structured data from Yahoo!.
    • Build a semantic Search Engine with BOSS documents how to use Yahoo's BOSS API to access Yahoo SearchMonkey which supports the hAtom, hCalendar, hCard, hReview, XFN, geo, rel-tag, adr microformats.

SearchMonkey

Yahoo SearchMonkey supports hCard, hCalendar, hReview, hAtom, others - launched 2008 May. SearchMonkey is Yahoo!'s program for collecting and displaying structured data, including microformats.

YQL

Yahoo Query Language uses an SQL-like syntax to "normalize" web service calls. In addition to wrapping web services such as Flickr, Yelp, and Zillow, YQL also enables you to extract content directly from web pages. As part of that functionality, YQL can query and filter on microformats. For example, the YQL query:

http://query.yahooapis.com/v1/public/yql?q=select * from microformats where url%3D'http%3A%2F%2Fupcoming.yahoo.com%2Fvenue%2F23933%2F'&format=xml

extracts all microformats from a particular page on upcoming.yahoo.com.

Unlike BOSS and the simple microformat filters described above, you can use YQL to perform filtering and other operations on the microformat data itself.
