The following list is a registry of common namespace mappings found in JCR applications. Note that the listed prefixes are not universal, as some repositories can use different mappings for the same namespaces. All prefixed names on this wiki and on the Jackrabbit web site use these mappings unless otherwise specified. Unless there is a good reason to do otherwise, you should avoid using these prefixes for different namespace mappings.
