Subject [jira] Created: (JCR-616) Completeness/Freshness of Namespace Registry
Date Fri, 03 Nov 2006 09:20:16 GMT
Completeness/Freshness of Namespace Registry

                 Key: JCR-616
                 URL: http://issues.apache.org/jira/browse/JCR-616
             Project: Jackrabbit
          Issue Type: Bug
          Components: SPI
            Reporter: Julian Reschke

We need to define the requirements on completeness and freshness of RepositoryConfig.getRegisteredNamespaces().

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...
