Subject [jira] [Commented] (OAK-169) Support orderable nodes
Date Fri, 06 Jul 2012 13:22:33 GMT

    [ https://issues.apache.org/jira/browse/OAK-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407978#comment-13407978
] 

Michael Marth commented on OAK-169:
-----------------------------------

Why would we not implement the ordering as a linked list, i.e. each child node has a pointer
to the next child node? That would just require one additional property per child node. What
am I missing?

> There are JCR clients that depend on the ability to explicitly specify the order of child
nodes. That functionality is not included in the MicroKernel tree model, so we need to implement
it either in oak-core or oak-jcr using something like an extra (hidden) {{oak:childOrder}}
property that records the specified ordering of child nodes. A multi-valued string property
is probably good enough for this.
