From martin.hepp at unibw.de Fri Nov 8 07:47:47 2013 From: martin.hepp at unibw.de (Martin Hepp) Date: Fri, 8 Nov 2013 07:47:47 +0100 Subject: [goodrelations] Purl.org Service Down / GoodRelations Specification Message-ID: Dear all: Unfortunately, the purl.org service, which is used to provide the permanent URIs for GoodRelations and hundreds of other vocabularies, is temporarily down for unknown reasons. This means that the GoodRelations specification is temporarily not available from its official location http://purl.org/goodrelations/v1 However, you can always retrieve it directly from its actual location http://www.heppnetz.de/ontologies/goodrelations/v1 If you want to fetch the HTML version directly, this is also possible via http://www.heppnetz.de/ontologies/goodrelations/v1.html The OWL version in RDF/XML is available from http://www.heppnetz.de/ontologies/goodrelations/v1.owl We hope that this issue will not persist for too long, but since purl.org is not under our control, there is little we can do about it at the moment.

You could either define one yourself in your own namespace, as described here: http://wiki.goodrelations-vocabulary.org/Documentation/Extensions # Defining the property foo:material a owl:ObjectProperty ; rdfs:domain gr:ProductOrService ; rdfs:range schema:Thing ; rdfs:subPropertyOf gr:qualitativeProductOrServiceProperty . Or you could reuse one from other GoodRelations extensions from this list: http://wiki.goodrelations-vocabulary.org/Vocabularies e.g. the FreeClassOWL ontology at http://www.freeclass.eu/freeclass_v1 has the property http://www.freeclass.eu/freeclass_v1.html#P_E67 ("base material"). Then you need to model the material. You CANNOT directly use www.productontology.org URIs, like http://www.productontology.org/id/Concrete since such URIs designate the *class* of all instances of concrete (in this sense: particles), but you need an individual (in OWL) to express "concrete" as a type of material. The most straightforward way is using DBPedia URIs whenever you need individuals and www.productontology.org URIs when you need types or classes. The full pattern would be # Describing a product @prefix gr: . @prefix pto: . @prefix dbpedia: . @prefix foo: . foo:ConcreteTube a gr:ProductOrService, gr:Individual ; a pto:Tube_(fluid_conveyance) ; # It is a tube gr:name "A single tube made from concrete" ; foo:material dbpedia:Concrete. # It is made from concrete. That should do the trick. We will consider adding a madeOf or material property to GoodRelations and propose it to schema.org.

And yes, I'd definitely be in favor of seeing a "material" or "madeOf" property added to GoodRelations and schema.org, as this would help webmasters define even more precisely certain elements on their pages. Thanks.
