The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-jmap-core/
Technical Summary JMAP-Core specifies a protocol for clients to access JSON-based data objects efficiently, with support for push and out-of-band binary data upload/download. This document was produced in conjunction with draft-ietf-jmap-mail, which is the first specific set of objects and access methods built upon the described mechanisms. Working Group Summary The initial proposal included an authentication method which was removed based on feedback from the HTTP and security groups that it would be controversial, instead JMAP-core just allows for an authentication layer to be present and restricts itself to the object transport over that layer. The object naming and other parts of core underwent significant revision based on feedback from the group, and it's been in roughly the same shape with consensus for the last 6 months as small consistency fixes were made and feedback from real world implementation was gathered. Document Quality The only known implementations of the latest protocol have been done by FastMail staff, but there exist multiple implementations of earlier drafts, and their authors have read the current drafts - they're just waiting until publication to update to the latest version. Both client and server implementations are available as open-source. The JMAP working group is small, but there have been multiple people who have read the document carefully - Chris Newman who is now listed as an author gave particularly detailed reviews. The authors of the various parts of the FastMail stack that are now implemented on this spec, and of the two test suites covering the spec, have also found multiple issues in the last 6 months which have fed back into the final document. Multiple email server vendors have indicated their intention to either add JMAP to their existing servers, or to build new services on top of the JMAP data model. Personnel The Document Shepherd is Bron Gondwana and the Responsible Area Director is Alexey Melnikov.
