A richer property specification is required in the process and maritime industries

The definition of an Item Property needs to be richer in order to specify sub-properties at an arbitrary depth, and to identify each of the property itself and its sub-properties as described in international standards.

(1)
New ABIE: PropertyIdentification A class for assigning identifying information for a property
BBIE: ID 1 An Identifier for the property.
BBIE: IssuerScopeID 0..1 A scope within which the issuer has assigned this identifier
ASBIE: IssuerParty 0..1 (Party) The party that issued this property identifier.

(2)
Additions to ABIE ItemProperty:
ASBIE: StandardPropertyIdentification 0..1 (PropertyIdentification) Identifying information for this property, assigned according to a standard system.
ASBIE: ItemSubProperty 0..n (ItemProperty) A property subsidiary to this property.

(3)
For symmetry but not specific to this requirement, add to ItemIdentification:
BBIE: IssuerScopeID 0..1 A scope within which the issuer has assigned this identifier

 

Example:

      <cac:ItemSubProperty>
        <cbc:Name>Temperature</cbc:Name>
        <cbc:ValueQuantity unitCode="C">100</cbc:ValueQuantity>
        <cac:StandardPropertyIdentification>
          <cbc:ID>ABA927</cbc:ID>

          </cac:IssuerParty>
        </cac:StandardPropertyIdentification>
