Dear all: We are planning the following minor extensions to the GoodRelations ontology. Please let us know as soon as possible if you have any comments on the proposed changes. All should be backward-compatible with existing code and data. 2010-07-27 Change Log 1. Added gr:hasMPN property for products and offers The Manufacturer Part Number or MPN is a unique identifier for a product, service, or bundle from the perspective of a particular manufacturer. MPNs can be assigned to products or product datasheets, or bundles. Accordingly, the domain of this property is the union of gr:ProductOrService (the common superclass of goods and datasheets), and gr:Offering. 2. Changed the text of gr:hasStockKeepingUnit slightly in order to differentiate from hasMPN 3. Added gr:valueReference property for value dependencies The superclass of properties that link a Quantitative Value or a Qualitative Value to a secondary Quantitative Value or a Qualitative Value that provides additional information on the original value. A good modeling practice is to define specializations of this property (e.g. foo:referenceTemperature) for your particular domain. 4. Added gr:addOn for indicating optional goods and services This property points from an Offering to additional Offerings that can only be obtained in combination with the first Offering. This can be used to model supplements and extensions that are available for a surcharge. Any Price Specification attached to the secondary Offering is to be understood as an additional charge. 5. Added gr:Offering to the range of gr:hasEligibleQuantity This allows limiting offers to certain quantities.
