ROR (Resources of a Resource), a fast growing independent XML format for describing any object of your content in a standard manner, so any search engine can be able to better understand that content. RORweb.com is the official ROR website.
ROR feed is an influential structured feed for describing all your objects to the search engines: products, services, reviews, discounts, images, events, schedule, podcasts, as well as anything you want.
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.
ROR was created before Google Sitemaps, as a way to describe website information for the search engines. ROR is much more than Google Sitemaps. Also, ROR Sitemaps are automatically readable by all search engines, including Google.
ROR was created before Google Base. But unlike Google Base, ROR is for all search engines, not just one. Any search engine can find your ROR information using this scheme: http://www.your-domain-name.com/ror.xml.
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):
title=”ROR” href=”http://your-site.com/ror.php” />
Alternatively you can simply create a tiny ror.xml file and use it to tell the search engines the real location of your ROR feed.
A ROR Sitemap is simply a special type of ROR feed, a feed that provides sitemap information to the search engines. The ROR team is working with several companies in defining new object types and attributes for everyone to use. ROR is spreading very fast. There are currently tens, if not hundreds, of thousands website using ROR.
