Within jackrabbit the term "qualified name" is used, when the internal representation of a JCR name is referred according to the usage of "fully-qualified name" within the JSR 170 specification.
Based on input by julian (Issue #449) the phrasing has been adjusted in JSR 283 to match the terminology used in XMLNS.
As of JSR 283
- Qualified Name -> refers to a JCR Name in the form prefix:localname
- Expanded Name -> is used for what was formerly called "fully-qualified name".
In order to avoid confusion i would suggest to fix the javadoc throughout the project and eventually add explanations in cases where method or class names are misleading.
