Statement to retrieve DID Documents

[andrea-dintino]

Since the W3C-DID method are (kinda) standardize, it should be easy to have a statement that resolves a DID (or at least just for did:dyne DIDs), this can come in handy in plenty of situations. Something like:

Given I resolve the did named 'myDid' and store into 'didDocument'

Input:

{
"myDid": "did:dyne:sandbox.zenswarm:HwSjX94eXVmVpqGnN6L5HD3rjSBwxJeNc9xByJKB83wB"
}

Output:

{
    "didDocument": {
        "@context": "https://w3id.org/did-resolution/v1",
        "didDocument": {
            "@context": [

This can be done by using the universal resolver, it is not working at the moment but it seems a simply GET to

https://dev.uniresolver.io/1.0/identifiers/*did*

[andrea-dintino]

For now I think it's enough that we resolve did:dyne What you mention, it's something we should look at in the near future :-)

[matteo-cristino]

We can perform a GET from https://dev.uniresolver.io/1.0/identifiers/*did* and in case of failure, if the did starts with did:dyne: then we can perform a GET from https://did.dyne.org/dids/*did* in this way it can work with all DIDs and even if the universarl resolver is down we can still resolve our DIDs

Statement:

Given I resolve the did 'my_did' from 'my_url' and save the output into 'my_variable'
