CQL-Java, version 1.0 - Changes

Changes between versions 0.7 and 1.0 of the cql-java distribution:

• Support for profiled relations and relation modifiers: we now recognise any non-key word as a relation or modifier, rejecting those that are not of the form prefix.name since these must be explicitly tied to a ``context'' (what used to be called a qualifier-set or index-set).
• Support for version 1.1 as described at www.loc.gov/standards/sru/specs/cql.html. Since this is a significant leap forward, the version numbering increases to the next major version.
• "Qualifiers" renamed as "indexes" throughout, to match what is now universal CQL terminology.

PLEASE NOTE THE FOLLOWING INCOMPATIBLE API CHANGES

• The class UnknownQualifierException is replaced by UnknownIndexException.
• The CQLTermNode method getQualifier() is replaced by getIndex().
