[New Model]: Shared CatenaX Identifier (UUIDv4)

[jacewski-bosch]

Model Description

A lot of released models reference the CatenaX ID. It would make sense to create a shared aspect for it. For simpler dependency management I would suggest creating a separate model for it.
For backward compatibility reasons, it might be necessary to create 2 or 3 versions of it, Since originally the CatenaXId was just added raw and unprefixed, while it has been changed to be prefixed by a UUID URN.

• version 1.0.0 describing the older unprefixed version
• version 2.0.0 describing the newer prefixed URN prefixed version
• version 1.1.0 allowing both

Relevant Standards

Example Data

see the following relevant snippet from an already released model.

MS1 Criteria

• The proposed aspect model does not exist already
• The proposed aspect model does not extend an existing aspect but introduces completely new functionality
• The proposal references a Catena-X use case
• Relevant standards are mentioned/linked
• A first draft of the data structure is provided in an example

[ZazraltMagic]

• [ok]model doesn't exist
• [ok] not relevant for shared aspect model
• [ok] not individual use case, for all BAMM models that uses catenaXId
• [ok] standard is linked, uuid with prefix
• [ok] example given

While you're at it - I think there is a general conversation to be had about how closely the models should be tied to Catena-X. There is a general consensus that Submodel Templates generated from SAMM should be proposed in the IDTA. The IDTA will not standardize something that is called "catenaXId". My proposal would be to avoid:

{
  "catenaXId": "foobar"
}

and to encourage something like

{
  "idType": "catenaXId",
  "value": "foobar"
}

Of course this is going to be ugly af when SAMM-properties are mapped to AAS-properties but it's the best I can think of.

[BirgitBoss]

The alternative might be also something like a property "assetId" and a value like
urn:dataspace:catena-x:caenaXId:foobar

or two models: one with an abstract identifier and another one derived from it with a catena-x specific ID

abstract id
catenaXId inherits from abstract id

@jacewski-bosch - can I assist you with the modeling in any way?
