Subject [jira] [Commented] (OAK-169) Support orderable nodes
Date Mon, 09 Jul 2012 12:40:33 GMT

    [ https://issues.apache.org/jira/browse/OAK-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409393#comment-13409393

Thomas Mueller commented on OAK-169:
------------------------------------

> I suggest that whoever works on this simply starts with whatever is easiest to implement.

At some point we will need to decide if we want efficient for support large child node lists
combined with orderable nodes. If yes, it would kind of rule out the solution with the hidden
oak:childOrder property, for large child node lists. For small child node lists it would still
be an option of course, and probably the faster option.

> 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.
