    abstract =  {JMAP (RFC8620) is a generic, efficient, mobile friendly and scalable protocol that can be used for data of any type. This makes it a good fit for migrations or data portability use cases. This extension adds additional features useful (but not limited to) those use cases. It adds a feature exposing details about the product, backend and environment of a JMAP server. It also adds a data model for extending the JMAP Response with log messages, particularly helpful for debugging.},
