3.2.1.1 Data object Identification and Traceability

• For identification, each RESQML data object must have a UUID. NOTE: For UUIDs, RESQML is case-insensitive.
• For traceability, RESQML uses EIP metadata, which includes information such as when a data object was created and updated and by what software.
• These stand-alone data objects are also informally referred to as top-level data objects or elements.

Both UUIDs and EIP are explained in Chapter 2 Standards and Technology Used in RESQML .

For information on how the UUID and EIP metadata can be used together to manage data object identity during extended data exchange during an interactive session, see 3.2.2 Using UUIDs and EIP Metadata for Traceability to Help Manage Different Versions of a Data Object .
