This is the archive of the goodrelations dicussion list

Dear all:

In the past weeks, we received a lot of valuable suggestions on how to 
improve the GoodRelations vocabulary. We tried to address all issues. 
Attached, please find the change log. A pre-release will be available 
later today.

In case any of the proposed changes would cause unwanted side-effects in 
your applications, please inform me at your earliest convenience.

The most important and the only potentially incompatible changes are that

- gr:description is now deprecated; we suggest using rdfs:comment instead
- gr:isListPrice is now deprecated and replaced by the more powerful 
gr:priceType property

The rest are vocabulary extensions or improvements that help increase 
the compatibility with Semantic Web applications.

Best

Martin


2009-05-05 Change Log
=================
- removed p1 namespace prefix (unused)
- added rdfs:label properties for all elements. For reasons of 
consistency, they are identical with the element identifiers (e.g. 
"BusinessEntity"). Ontologically significant individuals (e.g. days of 
the week) also contain the name of their superclass in parentheses (e.g. 
"Friday (DayOfWeek)").
- removed unused protege namespace prefix
- Expanded the descriptions of hasMaxValue and hasMinValue to indicate that
hasMaxValueFloat/hasMaxValueInteger, 
haxMinValueFloat/hasMinValueInteger, or hasValueFloat/hasValueInteger 
should be used when when specifying values.
- set gr:description to deprecated; use rdfs:comment now instead. This 
provides better tooling support.
- Added PayPal as a PaymentMethod.
- Added DeliveryModePickUp as a DeliveryMethod
- Added DeliveryModeFreight as a DeliveryMethod
- Added DeliveryModeOwnFleet  as a DeliveryMethod
- Added PublicHolidays as a DayOfWeek; This is a placeholder for all 
official public holidays at the LocationOfSalesOrServiceProvisioning. It 
allows specifying the opening hours on public holidays. If a given day 
is a public holiday, this specification supersedes the opening hours for 
the respective day of the week.
- Added gr:hasPOS ObjectProperty. This property states that the 
respective LocationOfSalesOrServiceProvisioning is a point of sale for 
the respective BusinessEntity. It allows linking those two types of 
entities without the need for a particular Offering.
- Added VersionInfo property
- Added terms:license statement http://creativecommons.org/licenses/by/3.0/
- Added rdfs:isDefinedBy statements to all elements
    <rdfs:isDefinedBy rdf:resource="http://purl.org/goodrelations/v1"/>
- Added LINK tag to XHTML document header,
<link rel="meta" type="application/rdf+xml" title="RDF/XML definition 
for the GoodRelations ontology" 
href="http://purl.org/goodrelations/v1.owl" />
- Added note that the return format of the ontology specification is 
determined by content negotiation - in order to get a particular format, 
append .owl or .html to the ontology URI.
- Added hasNAICS datatype property for attaching NAICS codes to 
BusinessEntities
- Addes hasISICv4 datatype property for attaching ISIC Rev. 4 codes to 
BusinessEntities.
- Added cardinality recommendations (constraints) to datatype and object 
properties by extending the rdfs:label elements.
- Added isVariantOf object property for modeling product model variants.
This states that a particular ProductOrServiceModel instance is a 
variant of another ProductOrServiceModel. It is pretty safe to infer 
that the variant inherits all quantitativeProductOrServiceProperties, 
qualitativeProductOrServiceProperties, and 
datatypeProductOrServiceProperties that are defined for the first 
ProductOrServiceModel.

Example:
foo:Red_Ford_T_Model gr:isVariantOf foo:Ford_T_Model
- Set isListPrice to DEPRECATED.

This boolean attribute indicates whether a UnitPriceSpecification is a 
list price (usually a vendor recommendation) or not. TRUE indicates it 
is a list price, FALSE indicates it is not. It is safe to assume by 
default that a UnitPriceSpecification that lacks this attributes is not 
list price.
DEPRECATED. Use gr:priceType property instead.

- Added new datatype property priceType: This attribute can be used to 
distinguish multiple different PriceSpecifications for the same Product 
or Service. It supersedes the former isListPrice property. The following 
values are recommended:

SRP: "suggested retail price" - applicable for all sorts of a 
non-binding retail price recommendations, e.g. such published by the 
manufacturer or the distributor. This value replaces the former 
gr:isListPrice property.

INVOICE: The invoice price, mostly used in the car industry - this is 
the price a dealer pays to the manufacturer, excluding rebates and charges.

- Added explicit namespace prefix in addition to the default:
    xmlns:gr="http://purl.org/goodrelations/v1#"
This may make life easier for ontologies that import GoodRelations. 
Note: Protegé deletes this statement when you open and save the ontology 
file.
