DPROD — Additional identifiers

Can additional identifiers be added to support a richer expression of product details? Assuming data products become ubiquitous and the structure and purpose of data products evolves then the labelling/identification may also evolve. The overall/end-to-end product handling environment itself should become more standardised (e.g. considering/speculating on an architecture, but potential future need may arise to for large scale catalogs & product discovery methods, product stores, data product supply chains, data economy etc.)
