Hi all,

Our latest implementation report for DID Core is available here:

https://w3c.github.io/did-test-suite/#spec-statement-summary

Here are the remaining items that the WG needs to discuss on the upcoming call:

#1: Are the hl, relativeRef, and service implementations
    independent enough?

Our numbers are looking good. We now have two method implementations for hl,
relativeRef, and service -- although, by the same implementer (Mattr). We'll
have to debate if that counts or not on the upcoming WG call. If there are two
independent implementers at Mattr that created their did:web and did:sov
implementations, then it should count. If not, there may still be a good
argument to count these as two independent METHOD implementations.

#2: Are we letting the JSON serialization keep
    unimplemented features?

The JSON serialization continues to lack implementations for datetime, double,
integer, and null. The WG has noted that they're going to keep those features
in the spec anyway in order to support the entire JSON data model.

#3: What are we going to do with deactivated, nextUpdate,
    and nextVersionId?

We are currently lacking implementation support for the following DID
Resolution features:

* deactivated
* nextUpdate
* nextVersionId

DID URL Dereferencing now has two independent implementations for most of the
features, but just barely.

Those are the three remaining items to discuss wrt. implementations, AFAIK.
