GoodRelations is a Web Ontology Language-compliant ontology for Semantic Web online data, dealing with business-related goods and services.^[3] It handles the individual relationships between a buyer, a seller and the products and services offered. In November 2012, it was integrated into the Schema.org ontology.^[4]

Usage

GoodRelations became popular owing to its success in improving search engine results.^[5]

By 2009, the ontology's Product concept was being used to describe over a million products and their prices.^[6] By 2013, GoodRelations had been adopted by the search engines Yahoo!,^[7]^[8] Google,^[7] and Bing.^[7] An analysis of online e-commerce data providers at that time found it to be the most prevalent ontology in use.^[7] As of mid-2015, GoodRelations had become the de facto ontology for e-commerce,^[8]^[9] and was in widespread use, having been adopted by retailers such as BestBuy.^[8]

GoodRelations is additionally used in academic studies of the Semantic Web,^[10]^[11] as a core ontology.^[7]^[9]

Example

A shop, restaurant, or store, and its opening hours, may be specified using GoodRelations as in this example, which also uses vCard and FOAF:^[12]
