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: In general, it's a good habit to always attach a rdfs:label that holds a human-readable representation of the value to instances of http://purl.org/goodrelations/v1#QuantitativeValueFloat http://purl.org/goodrelations/v1#QuantitativeValueInteger This will make it easier for clients to render such values. Example: # Point value foo:value1 a gr:QuantitativeValueFloat ; rdfs:label "100 g" gr:hasValueFloat "100.0"^^xsd:float ; gr:hasUnitOfMeasurement "GRM"^^xsd:string # Interval foo:value2 a gr:QuantitativeValueFloat ; rdfs:label "10 - 120 g" gr:hasMaxValueFloat "120.0"^^xsd:float ; gr:hasMinValueFloat "10.0"^^xsd:float ; gr:hasUnitOfMeasurement "GRM"^^xsd:string . The same holds for qualitative values, i.e. instances of http://purl.org/goodrelations/v1#QualitativeValue but I assume it's more obvious there, so they will regularly have a label anyway.
