What is ROR?
ROR (Resources of a Resource) is a rapidly growing independent XML format for describing any object of your content in a generic fashion, so any search engine can better understand that  content. 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. As the ROR format gets expanded, are all possible efforts is to re-use exisisting data structures and formats as much as possible.
Can I call my ROR feed something other than ror.xml?
Yes, of course. The name ror.xml is just the default name; that's where search engines look by  default. If they don't find it there they look for a <link> tag in your main page (between the <head> and </head> tags) eg: <link rel="alternate" type="application/rss+xml"  title="ROR" href="http://your-site.com/ror.php" />
