An optional run-time timestamp that indicates the exact moment this specific data instance was created or generated. 
This element provides a definitive point-in-time reference for the data payload itself. 
It is distinct from the design-time Dublin Core metadata which describes the model definition.
This timestamp is crucial for data versioning, caching, and synchronization in distributed systems.

Element sdc4:DMType / instance_id
Namespace No namespace
Annotations
 
An optional, globally unique identifier for this specific data instance. It is strongly recommended to use a UUID (Universally Unique Identifier).
This ID provides a persistent identity for the data that is decoupled from any storage or transport mechanism (e.g., filename, database primary key). 
It is essential for reliably tracking, updating, and referencing data in distributed systems, message queues, and data aggregation platforms.

An optional identifier for the specific version of this data instance. 
When paired with instance_id, it allows for a complete version history of a single data record.
The type is a string to accommodate various versioning schemes, such as simple integers ('1', '2'), semantic versioning ('1.2.1'), or timestamps.
