Subject [jira] [Commented] (OAK-168) Basic JCR VersionManager support
Date Thu, 05 Jul 2012 12:38:34 GMT

    [ https://issues.apache.org/jira/browse/OAK-168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407045#comment-13407045

Jukka Zitting commented on OAK-168:
-----------------------------------

Note that a versioning implementation should also take the somewhat unique access control
implications of versioning into account. For example, is access to a version history controlled
separately, or does it follow the access controls of the latest checked out version? What
about a version history with no checked out version?

> Versioning is a highly useful feature for many applications, so we definitely should
support that in Oak.
> We could start by adding a basic JCR VersionManager implementation that simply implements
checkin operations by copying content from a node to the respective version history under
{{/jcr:system/jcr:versionStorage}}.
> The next step would then be figuring out whether we want to expose such an operation
directly in the Oak API, or if a separate versioning plugin and an associated validator for
changes in the {{/jcr:system/jcr:versionStorage}} subtree works better.
> Based on that we can then proceed to implement more of the JCR versioning features.
