-Revision history for the "cql-java" package.
+Revision history for the CQL-Java package.
See the bottom of this file for a list of things still to do.
+1.0 [IN PROGRESS]
+ - Support for CQL version 1.2 as described at
+ http://www.loc.gov/standards/sru/next-version.html
+ based on support for version 1.1 as described at
+ http://www.loc.gov/standards/sru/cql/
+ Since this is a significant leap forward, the version
+ numbering increases to the next major version.
+
+0.7 Thu Sep 4 22:51:11 2003
+ - Support for profiled relations and relation modifiers:
+ 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).
+
+0.6 Tue Jul 29 23:33:56 2003
+ - Include Ralph's fix for CQLTermNode::toType1BER() to prevent
+ it surrounding multi-word terms in quotes when encoded into
+ BER packet.
+
+0.5 Wed Feb 5 15:50:57 2003
+ - Add an extra back-end method,
+ byte[] toType1BER(Properties config)
+ which generates an opaque BER-encoded PDU suitable for
+ forwarding to Z39.50 server as a pasrt of a searchRequest
+ APDU. This was contributed by Ralph Levan <levan@oclc.org>
+ - Add srw.resultSet support to the toPFQ() method.
+ - Add new resultSetName() method to CQLNode and its
+ subclasses, returning the name of the referenced result-set
+ for a node that is just a result-set reference, and null for
+ anything else.
+ - Change regression-test rules for Adam's compiler to use his
+ new front-end cql2xcql instead of the old cqlparse3.
+ - Change the names of the anchoring properties in
+ etc/pqf.properties and the CQLTermNode code that examines
+ them, in accordance with Adam's PQF-renderer's behaviour.
+ This gives more flexibility in terms of generating
+ attributes for end-of-field anchoring. Various other minor
+ tweaks to the pqf.properties file, mostly to the comments.
+ - Change the capitalisation of the project name from
+ "cql-java" to "CQL-Java". That doesn't really make any
+ difference to anything: in particular, file-names such as
+ "cql-java.jar" remain the same.
+
0.4 Thu Nov 21 10:09:26 2002
- Add support for the new "phonetic" relation modifier,
including its mapping in "etc/pqf.properties".

### Still to do
+ - Test-harness option to use Type1 BER back-end.
+ - Case-insensitive matching for serverChoice and any other
+ special-case qualifiers. (Are the configured qualifiers
+ matched case-insensitively? They should be.)
+ - Prefix-aware matching for serverChoice, so that
+ >x="http://www.loc.gov/zing/srw/dc-indexes/v1.0/" x.resultSet=foo
+ does the right thing.
+ - Extend test-suite for PQF and BER renderers.
+ - Additional test-suite entries for things like
+ case-sensitivity.
+ - Add a new configuration file that allows arbitrary new
+ relations and relation modifiers to be defined.
- Fix the bug where "9x" is parsed as two tokens, a TT_NUMBER
followed by a TT_WORD. The problem here is that I don't
think it's actually possible to fix this without throwing
out StreamTokenizer and rolling our own, which we absolutely
- _don't_ want to do.
- - Add srw.resultSet support to the toPFQ() method.
- - Write some "glue" code to generate a BER-encoded Type-1
- query packet using ZJKit's PQF-compiler and the facilities
- for serialising the resulting Type-1 tree representation.
+ - Fix term-to-PQF translation to omit empty properties
+ (for the broken Korean server)
- Write "package.html" file for the javadoc documentation.
- Some niceties for the cql-decompiling back-end:
* Don't emit redundant parentheses.
* Don't put spaces around relations that don't need them.
- - Consider the utility of yet another back-end that translates
- a CQLNode tree into JZKit's representation of a Type-1 query
- tree. That would be nice so that CQL could become a JZKit
- query-type; but you could achieve the same effect by
- generating PQF, and running that through JZKit's existing
- PQN-to-Type-1 compiler.
- Many refinements to the random query generator:
* Generate relation modifiers
* Proximity support
* Generate multi-word terms
* Generate prefix-mappings
