Re: DID Formal Objection Status Update (Dec 2021)

Here's an example of an application-level DID method/object name space... this is an (abstract) example of a purchase VC/application object identified by the DID:
did:tdw:po:289303:1

And just to be clear, /none/ of those items that you mention have anything to do with DID methods. DID method identifiers are not namespaces for any of those things.

There is a bit of an multi-organization-specific complication here:
- how are ABC Grocery's purchase orders (identified by a simple integer PO number) to be differentiated from David's Cabbages purchase orders (also identified by a simple integer PO order number from a potentially overlapping range of PO numbers)?

In the real world, we need to work with overlapping sets of basic identifiers that are only unique within a specific realm, for example...
- purchase order and invoice numbers from multiple organizations,
- waybill numbers may already have an industry solution,
- part numbers from different manufacturers,
- objects and collections of objects identified by a GraphQL or OData query sourced from different realms or collection of realms based on the same underlying query string
- in-house enterprise application developers, DBAs, and data modelers creating object name spaces for every object in their enterprise architecture ... similar/same challenges Implementors currently have selecting name spaces for their C#, Java, etc. application components.
- etc. etc. etc.

Apologies if I've ruined your "morning"... 😉🙂,
