Dear all:
Based on many bilateral discussions, I have updated the proposal for cars and other vehicles [1] and the property-values mechanism for product feature data [2].
A live demo is up and running at
http://sdo-property-value.appspot.com/
The proposal updates schema:Car (new:http://sdo-property-value.appspot.com/Car) and schema:Vehicle (new: http://sdo-property-value.appspot.com/Vehicle). It incorporates and is aligned with the Yandex proposal for cars [3] (Yuliya and I analyzed the overlap).
A Github fork based on sdo-venkman is available at
https://github.com/mfhepp/schemaorg/tree/property-value-and-cars
I have already created a respective pull-request to https://github.com/danbri/schemaorg/tree/sdo-venkman.
In effect, it adds the following elements:
1. Types for common vehicle categories
--------------------------------------
http://sdo-property-value.appspot.com/MotorizedRoadVehicle
http://sdo-property-value.appspot.com/Truck
http://sdo-property-value.appspot.com/Van
http://sdo-property-value.appspot.com/MotorizedBicycle
http://sdo-property-value.appspot.com/BusOrCoach
http://sdo-property-value.appspot.com/Motorcycle
http://sdo-property-value.appspot.com/Bike
http://sdo-property-value.appspot.com/Watercraft
http://sdo-property-value.appspot.com/Boat
http://sdo-property-value.appspot.com/MotorBoat
http://sdo-property-value.appspot.com/SailingBoat
plus a few utility types for quantitative values.
2. Properties for common, vendor-independent car features
---------------------------------------------------------
For a list, see here:
http://www.w3.org/wiki/WebSchemas/Vehicles#New_Properties
3. A type for exposing semi-structured product and place feature information
----------------------------------------------------------------------------
http://sdo-property-value.appspot.com/PropertyValue
plus three new properties for this type:
additionalProperty
propertyID
unitText
plus slight modifications to unitCode, minValue, maxValue, value, and valueReference:
https://www.w3.org/wiki/WebSchemas/PropertyValuePairs#Changes_to_Existing_Elements
4. A mechanism for exposing standardized and vendor-specific EXIF image meta-data to schema:ImageObject
-------------------------------------------------------------------------------------------------------
This happens by simply including schema:PropertyValue to the range of schema:exifData, see
http://sdo-property-value.appspot.com/ImageObject
Examples for the use for EXIF meta-data are here:
https://www.w3.org/wiki/WebSchemas/PropertyValuePairs#ImageObject:_EXIF_Meta-data
See also
https://www.w3.org/wiki/WebSchemas/PropertyValuePairs#EXIF_Image_Meta-data
The proposal comes with a full set of examples in Microdata, RDFA, and JSON-LD; only the property-value examples are currently given in Microdata only. I can add them on other syntaxes if needed.
I hope that this final specification addresses all issues from the previous discussions and can be agreed upon.
Best wishes
