Subject [jira] Commented: (JCR-616) Completeness/Freshness of Namespace Registry
Date Fri, 03 Nov 2006 12:34:17 GMT
    [ http://issues.apache.org/jira/browse/JCR-616?page=comments#action_12446931 ] 
            
Julian Reschke commented on JCR-616:
------------------------------------

One problem with approach 4) is that in some backend systems, users can set arbitrary custom
properties. That is, there is no namespace registry at all, and the set of namespaces used
by properties can be really large. I think an SPI design that requires the remote server to
return all of these mappings -- even if they may be not be used -- would be a bad idea.

> Right now the optimistic assumption seems to be that an SPI provider is able to report
all namespaces that can occur in a repository beforehand. Even if it can do that (and I know
of potential targets for SPI that simply can't), this seems to be quite a waste of time if
these namespace prefixes aren't actually used later on.
> Furthermore, in SPI namespace prefixes aren't really relevant, except to enable the transient
layer to return "meaningful" prefixes instead of automatically generated ones.
> Therefore my propoal would be to:
> 1) Clarify that the Map returned from getRegisteredNamespaces() isn't required to be
complete,
> 2) Enhance JCR2SPI to auto-generate prefixes when it encounters namespaces not in the
registry.
> I expect this to also affect RepositoryService.(un)registerNamespace(...), but let's
discuss the underlying issue first...
