A collection of technologies that allow publishing of search results in a format suitable for syndication and aggregation. It is a way for websites and search engines to publish search results in a standard and accessible format. Originally developed by Amazon and recently adopted by Yahoo!, __________ relies on abstract-based microformats (dataRSS, eRDF, FOAF, GeoRSS, hCard, hEvent, hReview, hAtom, MediaRSS, RDFa, XFN, etc.) to integrate syndicated content into search results.
