Re: Discussion topic: How to improve understanding and application of schema.org

Webfeet, yeah you have the first parts pretty much right, but maybe the
inheritance part not as much though. It's tricky stuff, I'll give you an
example.

*Individual iPhones* and *iPhone types*:

*Thing*
*    MobilePhone*
*        Smartphone*
*            iPhone*
*                iPhone7*
*                iPhone8*
*                iPhoneX*
                    iPhoneX (serial number 00000001)
                    iPhoneX (serial number 00000002)
                    iPhoneX (serial number 00000003)
*    ThingType*
*        MobilePhoneType*
*            SmartphoneType*
*                iPhoneType*
                    iPhone 7
                    iPhone 8
                    iPhone X


Example description of an *individual iPhone*:

iPhoneX (serial number 00000001)
    serialNumber: 00000001
    height: 5.651 inches
    width: 2.789 inches
    depth: 0.299 inches
    weight: 6.139 ounces

Example description of an *iPhone type*:

iPhoneX
    heightOfTypicalInstances: 5.65 inches
    widthOfTypicalInstances: 2.79 inches
    depthOfTypicalInstances: 0.3 inches
    weightOfTypicalInstances: 6.14 ounces


Having types always exist in pairs, like iPhone existing with iPhoneType,
creates a pattern, and patterns can potentially help understanding.

I took the following definitions from Apple, maybe they help explain what's
going on too:

   - *Instance properties*: Properties belonging to an instance of a
   particular type.
   - *Type properties*: Properties that define values universal to all
   instances of a particular type.
