Overview

This table lists all use cases relevant for describing, storing, reading and managing configurations.

The columns "OSGi", "ConfMgr" and "wcm.io Conf" describe if the existing implementations already cover this use case.

The last two columns "Sling Conf" and "wcm.io Conf V2" defines if this use cases should be covered by the new solution split up in Sling and wcm.io, and with which priority.
