a powerful structured feed for describing all your objects to the search engines.

ROR (Resources of a Resource) is a rapidly growing independant XML format for describing any object of your content in a generic fashion, so any search engine can better understand that content. RORweb.com is the official ROR website.

ROR promotes the concept of structured feeds (which is related to the concept of structured blogging) enabling search engines to complement text search with structured information to better understand meaning. ROR information is typically stored in a ROR feed called ror.xml placed in your website's main directory. Unlike Google Base, ROR feeds can be easily accessed by all search engines: at http://www.your-website-name.com/ror.xml
You can think of your ROR feed as a powerful structured feed for describing all your objects to the search engines: products, services, reviews, discounts, images, events, schedule, podcasts, anything you want.
