GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

Martin makes an excellent point, easily lost when one tries to grok the totality of GoodRelations ontology. In short, the simplicity of the other products can be had by using a subset of GoodRelations so there is nothing lost. There is much gained because it is extensible. IDEA: create documentation and tools for one or more simple subsets of GR, analogous to OWL-Lite, OWL-DL, and OWL-Full.
