Help Search Engines get Smarter, ROR your Website!

Thread Description:
I originally picked up ROR from this article on GetSeattle.com. Where it says:

ROR suggests a better approach. Since search engines already come to your site to read text information about your products, it makes sense to also read additional information like prices, image URLs, discounts, etc. This way, you only change the information once, in your ROR file, and that's it. Product information is just one example but it illustrates this issue rather well.

ROR stands for 'Resources of a Resource' and their website describes it as:

ROR is a simple flexible XML and RDF vocabulary for describing the resources of a resource (e.g. objects of a website, entries of a blog or feed, a list of things, a group of people, a directory, etc).
The idea behind ROR is to describe resources by decomposing them into ever smaller resources that can be described more fully and precisely, making it easier for web agent or applications (e.g. search engine spiders, content aggregators, etc) to make sense of the information.

This is a service of addme.com and it looks interesting on my initial look. They have a specification here and it seems some thought has gone into it.
