See http://www.heppresearch.com/gr4google This is a major - if not the critical - step towards massive adoption of RDF, because there is now a clear incentive for any site owner in the world to add rich meta-data in RDFa to her or his page templates. It is also, to my knowledge, the first OWL DL vocabulary adopted by a major search engine. It is safe to assume that additional GoodRelations elements, not currently relevant for Rich Snippets, and RDF features currently not required by Google (e.g. datatype information), will not irritate Google's processing of RDFa markup, so you can cater for Google and the Web of Linked Data in one turn if you follow the recipe from my page given above. I would like to take this opportunity to thank all of the many individuals who supported my work on GoodRelations in one way or another over the past years, namely Andreas Radinger, Alex Stolz, Uwe Stoll, Kavi Goel, Kingsley Idehen, Jay Myers, Peter Mika, Stephan Decker, Jamie Taylor, Andreas Harth, Aldo Bucchi, Giovanni Tummarello, Richard Cyganiak, Jon Udell, Daniel Bingel, Markus Linder, Martin Schliefnig, Andreas Wechselberger, Leyla Jael Garcia, and many others. All of them have provided valuable suggestions and feedback, encouragement, or both. This is a great day for the Semantic Web and Linked Data. Now please spread the word!

An RDF repository that uses the respective axioms from http://www.ebusiness-unibw.org/wiki/GoodRelationsOptionalAxiomsAndLinks will then replicate all product properties from the super-product, unless they are defined differently at the level of the variant. Note that this only holds for product properties, not for arbitrary RDF properties, so you would have to make them subproperties of one of the three GR properties: gr:qualitativeProductOrServiceProperty gr:quantitativeProductOrServiceProperty gr:datatypeProductOrServiceProperty A simpler solution is to model - just one model, - use two gr:Offerings of the same product, one for the download and one for the CD and one for the download, and - indicate that the latter is a download by setting the delivery mode to http://purl.org/goodrelations/v1#DeliveryModeDirectDownload If the price is the same you could also just model one model, one offering, and say that delivery is available via various parcel services and via gr:DeliveryModeDirectDownload. Note that gr:isVariantOf is not strictly transitive (because of the defaults).

GoodRelations will work for you and there is no need to unsubscribe from this list; such topics are a rare exception. Dear all: Based on very valuable input from Thorsten Liebig from derivo.de, we evaluated whether GoodRelations could be made fit into the OWL 2 RL profile, instead of just OWL 1 DL, as currently. It turns out that this would require modifications that we cannot implement right now: 1. GoodRelations needs the xsd:time datatype for opening hours (gr:opens and gr:closes), but xsd:time is not an OWL 2 datatype. We could use a proprietary datatype, but that would remove the possibility to used xsd:time datatype validators, which have, in the past, spotted quite some bugs in markup. 2. The owl:unionOf constructs for the domain definition of several object and datatype properties cannot be replaced without introducing "ugly" top-level classes. For example, gr:validFrom and gr:validThrough can currently be attached to gr:Offering, gr:PriceSpecification, and gr:OpeningHoursSpecification. The alternative modeling would be defining a common superclass "entities with temporary validity", which would make the conceptual model ugly and would also never be used for annotating data. In my opinion, the unionOf constructs don't really harm, since -- except for some validation tools -- they can be safely ignored by any GoodRelations-aware client. The xsd:time datatype is widely supported by RDF repositories and validators and is thus also safe to use. Conclusion: For the moment, GoodRelations stays within the OWL 1 DL fragment. Again, thanks to Thorsten Liebig for bringing up these issues.

URIburner implements the "Sponger" technology from Openlink Software, which is, simply put, a piece of intelligent middleware that accesses a public API associated with a Web site, fetches data for the current page (e.g. by spotting the Amazon identifier from the URI pattern), and transforms this information into GoodRelations RDF data. Thus, there is currently no way to access Amazon data in RDF without using URIburner.

I don't know whether goodrelations can describe the relation between different commodities, which is neccessary to recommendation system. For example, I have four commodities: necktie, skirt, western-style clothes and handbag, and I have defined some relations among these commodites: relation(necktie, western-style clothes) = accessory, recommeding weight = 0.9 relation(handbag, skirt) = collocation, recommending weight = 0.85 relation(necktie, skirt) = exclusion, recoomending weight = 0.3 Can goodrelations describe those relations? In addition, is there any example about the commodity ontology described by goodrelations? I don't show my commodities on the web and only manage them. I appreciate for your help.

Payment options in GoodRelations are about describing how you can settle the payment in case you accept the respective offer. So GoodRelations covers the pre- transaction part, and the payments ontology from above may be used to expose spent data. Best wishes Martin Hepp
