Subject [jira] [Commented] (OAK-169) Support orderable nodes
Date Mon, 09 Jul 2012 10:49:34 GMT

    [ https://issues.apache.org/jira/browse/OAK-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409318#comment-13409318

Jukka Zitting commented on OAK-169:
-----------------------------------

bq. I guess to decide which approach works best in practice we first need have to define which
use cases we care about and which are the most common ones.

Agreed.

Meanwhile I suggest that whoever works on this simply starts with whatever is easiest to implement.
Once we have something that runs and implements this functionality, we can revisit this discussion
based on numbers from performance benchmarks that reflect actual performance-critical use
cases.

> 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.
