NDR for interchange creation from RDM

[onthebreeze]

we need to formalise the rules by which the CEFACT published RDM is transformed to the interchange format. We use the MMT CSV for this task and we define mappings to the terms define in the domain model

Dictionary Entry Names (DEN) are represented in the MMT as

{qualifier}_ entity.{qualifier}_ property.{qualifier}_ coreType.

and are transformed to lower camel case with qualifier terms retaining the underscore postfix

MMT CSV	Domain Model	comment
ABIE DEN	entity:name removing "details" qualifier	For example Logistics_ Transport Equipment. Details -> Logistics_TransportEquipment
ABIE Definition	entity:description	remove any formatting
BBIE DEN	property:name	For example Logistics_ Transport Equipment. Tare Weight. Measure -> tareWeight
BBIE definition	property:description	remove any formatting
BBIE DEN type part - Core Data Type	reference to the data type from Core Data Types package of the name DEN without entity qualifier and with prefix Type_Code(just _Code if property is Type)	for example Logistics_ Transport Means. Type. Code -> reference to the data type with the name "TransportMeansType_Сode"
BBIE DEN type part - MMT Code	reference to the data type from MMT Codes package of the name DEN without entity qualifier and with prefix Type_Code(just _Code if property is Type)	for example Logistics_ Transport Means. Type. Code -> reference to the data type with the name "TransportMeansType_Сode"
BBIE DEN type part - ISO Code	reference to the corresponding data type from ISO Codes package	for example Header_ Trade Settlement. Invoice_ Currency. Code -> reference to the data type with the name "ISO4217_Code"
BBIE Occurrence min/max : property:cardinality	for example Occurrence Min 0 and Max 1 -> 0..1
ASBIE DEN, property part	contained (source) relationship:name	for example Logistics_ Transport Equipment. Loading. Transport_ Event -> contained relationship with name "loading"
ASBIE DEN, type part	referenced (target) ABIE name	for example Logistics_ Transport Equipment. Loading. Transport_ Event -> reference to ABIE named "transport_event"
ASBIE Occurrence min/max	relationship:cardinality

Other rules

• whenever there are more than two relationships between the same two entities then replace them with a single relationship with 0..* cardinality that has a property with name role - and the property has a related dateType with name equal to {source ABIE name}_{taget ABIE name}. for example

• Logistics_ Transport Equipment. Operating. Trade_ Party

• Logistics_ Transport Equipment. Loading. Trade_ Party

• Logistics_ Transport Equipment. Carrier. Trade_ Party

• Logistics_ Transport Equipment. Notified. Trade_ Party

are replaced with a relationship called logistics_transportEquipment.trade_party that has a property with name role that has a data type logistics_transport_Equipment.trade_party that has enumerartion values operating, loading, carrier, notified

Lets give this a go. There remain two to-dos

• talk to CEFACT about the enumeration values for all the code data types of BBIEs.
• figure out some rules about removing other superfluous qualifiers.
