PROPOSAL: Universal values for a *null DID* as well as an *empty DID*

[mwherman2000]

These concepts are very common place in the world of software development today.

e.g. null string = 0; empty string = "";
e.g. null array = 0; empty array = [];

PROPOSAL: Universal values for a null DID as well as an empty DID (universal => DID Method independent):

null DID = "did:0";
empty DID = "did:";

including pre-defined functions like: bool nullempty = Did.IsNullOrEmpty(someDIDvalue);

Any other ideas/proposals?

There's a spec and specific implementation for the did:null method:

• https://digitalbazaar.github.io/did-method-null-spec/
• https://github.com/digitalbazaar/did-method-null

The entire concept was rejected from the registry:

• Add did:null method. did-extensions#431
• Add did:null method. did-extensions#555

Maybe I'll refresh and try again on April 1. :-)

did:0 and did: are not valid based on the DID spec. I saw no reason to challenge that and picked did:null:null for naming as it seemed to best align with web platform terminology and DID spec expectations. I figured character counts were not really important. Mostly because the idea was either as a joke or as something real that is simple and static that does nothing but could be used for a minimal base case for test suites or checking validators or something.

@davidlehn Thank you for engaging. Your comment suggest an alternative. This is no joke.

did:constant:null
did:constant:empty
