GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

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.

[goodrelations] rdfs:label for quantitative values

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.
