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
Martin Hepp
