Universal Resolver Driver: did:scid

This is a Universal Resolver driver for did:scid identifiers.

(work in progress)

Specifications

• Decentralized Identifiers

• DID SCID Resolution Overview

Architecture

This driver depends on other drivers of did:scid "source DID methods". At the moment, these are:

• did:webvh driver source image
• did:webs driver source image

This driver also depends on "?src" dereferencers, which can process values of the ?src DID parameter used by did:scid:

• DidUrlSrcDereferencer
• DomainSrcDereferencer
• HederaUriDereferencer

Build (native Java)

mvn clean install

Driver Environment Variables

The driver recognizes the following environment variables:

uniresolver_driver_did_scid_didResolverUri

• The endpoint of a DID Resolver that can dereference DID URLs as the value of the "src" parameter.
