The vcr:ItemInstance element is used to convey data on a specific instance of the delivered article, and comprises a sequence of the SerialID elements for communicating serial numbers. No distinction is made between serial numbers which uniquely identify an article instance, e.g. a frame number for a frame, and serial numbers which uniquely identify only certain characteristics of an object, e.g. a key number which uniquely identifies only a key's closure, but not the individual key.
The SerialID element extends xsd:normalizedString with the following attributes:
Name | Type/occurrence | Description |
|---|---|---|
kind | vcr:SerialIDKind/required | Type of serial number. |
description | xsd:string/optional | Descriptive text. |
The serial number is then the content of this element.
The related attribute of type vcr:SerialIDKindType serves to distinguish between the following types of serial number:
FrameNumber:
The frame number is an alphanumeric code indicated via engraving or a label on the frame, often near the pedal bearing or control head. Due to existent redundancies, the frame number is not recommended as a unique identifier..
SerialNumber:
The entire vehicle's specific serial number. It is often indicated on the frame by the manufacturer via a label, and normally allows at least manufacturer-specific unique assignment.
SerialNumberDisplay:
A serial number near the pedelecs and S-pedelecs for the installed display (usually on the handlebars).
SerialNumberBattery:
Serial number of batteries in the case of electric vehicles. For vehicles with more than 1 battery, corresponding identification is needed in the 'Description' element of ItemInstanceElement (e.g. "battery bottom tube" / "battery top tube" or also "battery 1" / "battery 2").
KeyNumberFrameLock:
Key number for locks firmly mounted on the frame.
KeyNumberBattery:
Key number used to identify locks for batteries and battery holders in the case of electric vehicles.
SerialNumberMotor:
Motor's serial number in the case of electric vehicles.
SerialNumberGearHub:
Serial number of gear hub.
Other:
For further serial numbers not related to the parameters above. The type of identification involved here is to be precisely defined in the description.
