Implementations readiness and spec maturity

This page summarizes the current understanding of different aspects of the OCM specifications and the existing implementations

Capability	Status	Usage and maturity
Discovery endpoint	Production	ownCloud on v1.1 format, others incl. CERNBox and Nextcloud on v1.2+
Invite endpoint	Production	All known implementations can interoperate
Sharing of Files/Folders via webdav	Production	Most implementations interoperate, with different auth methods
Notifications of changes to shares	-	Implemented in Nextcloud and oCIS BUT broken interoperability
Sharing of Telcos and participants via talk	Production	Implemented in Nextcloud only
Synchronization of calendar objects	Production	Implemented in Nextcloud only
Sharing of Files via webapp	Prototype	Demonstrated by CERNBox and Nextcloud
Sharing of Files/Folders for datatx access	Spec	Partially demonstrated as part of the ScienceMesh project in 2022
Sharing of Files/Folders via ssh	Prototype	PoC exists, FileSender is considering adoption
Enforce criteria in a share	Spec	No implementations yet
Enforce must-exchange-token requirement	Production	Implemented in Nextcloud and CERNBox
