[jira] [Created] (OAK-11397) Provide a way to get expanded names for items

Konrad Windszus created OAK-11397:
-------------------------------------

             Summary: Provide a way to get expanded names for items
                 Key: OAK-11397
                 URL: https://issues.apache.org/jira/browse/OAK-11397
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Konrad Windszus
            Assignee: Konrad Windszus


The expanded form name (https://developer.adobe.com/experience-manager/reference-materials/spec/jcr/2.0/3_Repository_Model.html#3.2.5.1%20Expanded%20Form) is in general more stable than the qualified form, due to global/session remappings.
Therefore it is often beneficial to work with it. Also the JCR API only defines constants for the expanded form (https://javadoc.io/doc/javax.jcr/jcr/latest/constant-values.html).

Although all JCR method taking a JCR name/path accept both forms there are edge cases where one doesn't use it as JCR method argument.

For example when checking if a given node name is contained in a Set of literals (e.g. in https://github.com/apache/jackrabbit-filevault/blob/a2629fd3a24d35f31f0168bd6b8982db6ac62c8b/vault-core/src/main/java/org/apache/jackrabbit/vault/fs/filter/BaseFilter.java#L57).

Therefore a way to get the expanded form name of a given javax.jcr.Item should be provided.
