Should a semi-colon be allowed in a specific-idstring? #3

Closed mrinalwadhwa closed 5 years ago

mrinalwadhwa commented 6 years ago

The current version of the DID spec includes examples like this: did:example:123456789abcdefghi;photos

However the grammar doesn't allow that semi-colon. Does this mean that specific schemes can override the generic scheme? 

did-reference      = did [ "/" did-path ] [ "#" did-fragment ]
did                = "did:" method ":" specific-idstring
method             = 1*methodchar
methodchar         = %x61-7A / DIGIT
specific-idstring  = idstring *( ":" idstring )
idstring           = 1*idchar
idchar             = ALPHA / DIGIT / "." / "-"

Dmitri Zagidulin wrote: the example URIs in the spec that contain semicolons aren't DIDs themselves, they are DID-based Service URIs. (The semicolon is a proposed mechanism to separate the DID part from the service locator part). Take a look at the discussion at that PR #90
