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.

Dear all: We pretty much finalized a service update for GoodRelations, which mainly defines a few additional properties that are important for the rental and accommodation business. Also, we redesigned the language reference in HTML completely. Except for a few minor issues listed below, the update is fully backwards-compatible and should not break existing data or code. A preview is available at http://www.heppnetz.de/ontologies/goodrelations/20100412/v1.html http://www.heppnetz.de/ontologies/goodrelations/20100412/v1.owl An UML diagram highlighting the planned extensions is at http://bit.ly/cRTRE6 A change log is at http://bit.ly/dhXqY9 Please report any suggestions or feedback before Thursday, April 22, 2010. We plan to officially release the service update on Friday. Highlights: ========== - validity dates for opening hours - new gr:owns property for indicating the products that you own, which allows exposing ownership data for future recommender systems - availability intervals for offers, important for rental businesses - eligible contract durations and advance booking requirements - shipping and delivery charges can now be constrained to order volumes in terms or quantity or a monetary amount ("free shipping from 20 USD onwards..." - ordering relations for qualitative values, which may be useful e.g. for modeling garment sizes (XL>L>M>S) etc. Backward Compatibility: ====================== The only changes that may (but should not) affect existing data or code are the following: 1. We removed the rdfs:range statement for gr:legalName. It used to be xsd:string, but that prevented someone from indicating the natural language, since the language tag can only be attached to untyped RDF literals. 2. We changed the domain of gr:validFrom and gr:validThrough to the union of gr:Offering, gr:OpeningHoursSpecification, and gr:PriceSpecification instead of just gr:Offering and gr:UnitPriceSpecification. This allows specifying the validity interval of offers, opening hours, payment charge specifications, and delivery charge specifications. The rest are either fixed typos or additional language elements that are fully backwards compatible.
