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.

Best wishes
