Subject [jira] Commented: (JCR-2275) some legal jcr names cause unneccessary server-roundtrips
Date Wed, 26 Aug 2009 10:09:59 GMT

    [ https://issues.apache.org/jira/browse/JCR-2275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747876#action_12747876

Jukka Zitting commented on JCR-2275:

Instead of custom rules like this, I'd rather use the expanded form rule that the URI part
always contains a colon. Thus the following test will always detect whether a name is in expanded

   name.startsWtih("{") &&  name.indexOf(':") != -1

The only problem is the "internal" namespace used with the "rep:" prefix. For now we can treat
that as a special case:

   name.startsWtih("{") &&  (name.indexOf(':") != -1 || name.startsWith("{internal}"))

I would also recommend that we migrate from "internal" to using a proper namespace URI like

> assume the following legal qualified jcr names:
> "{foo}"
> "{foo} bar"
> when items with such names are read from the spi layer, they are first interpreted as
expanded form names.
> a prefix lookup for namespace 'foo' fails and the name is treated as qualified jcr name.
> => depending on the spi implementation, a server-roundtrip is required in order to
determine that 'foo' is not a
> registered namespace.
