'''GoodRelations''' is a Web Ontology Language-compliant ontology for Semantic Web online data, dealing with business-related goods and services.{{sfn|Antoniou|Harmelen|Hoekstra|2012|p=176}} 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.{{sfn|Hepp|Hoffner|2014|p=34}}
==Usage== GoodRelations became popular owing to its success in improving search engine results.{{sfn|Antoniou|Harmelen|Hoekstra|2012|pp=176-177}}
By 2009, the ontology's ''Product'' concept was being used to describe over a million products and their prices.{{sfn|Siegel|2009|p=71}} By 2013, GoodRelations had been adopted by the search engines Yahoo!,<ref name="ashraf">{{cite journal |quote=To comprehensively understand the usage patterns of conceptual knowledge, instance data, and ontology co-usability, we considered GoodRelations ontology as the domain ontology and built a dataset by collecting structured data from 211 web-based data sources that have published information using the domain ontology. |doi=10.1002/cpe.3089 |date=4 July 2013 |title=Empirical analysis of domain ontology usage on the Web: eCommerce domain in focus |first1=Jamshaid |last1=Ashraf |first2=Omar Khadeer |last2=Hussain |first3=Farookh Khadeer |last3=Hussain |volume=26 |issue=5 |pages = 1157–1184|journal=Concurrency and Computation: Practice and Experience |s2cid=44337539 }}</ref>{{sfn|Sikos|2015|p=16}} Google,<ref name="ashraf" /> and Bing.<ref name="ashraf" /> An analysis of online e-commerce data providers at that time found it to be the most prevalent ontology in use.<ref name="ashraf"/> As of mid-2015, GoodRelations had become the ''de facto'' ontology for e-commerce,{{sfn|Sikos|2015|p=16}}<ref name="Vojtěch">{{cite journal |doi=10.1016/j.websem.2016.07.002 |title=Adapting ontologies to best-practice artifacts using transformation patterns: Method, implementation and use cases |first1=Vojtěch |last1=Svátek |first2=Marek |last2=Dudáš |first3=Ondřej |last3=Zamazal |journal=Web Semantics: Science, Services and Agents on the World Wide Web |volume=40 |pages=52–64 |date=October 2016 }}</ref> and was in widespread use, having been adopted by retailers such as Best Buy.{{sfn|Sikos|2015|p=16}}
