-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.
+0.5 (IN PROGRESS, currently at RC1)
+ - Add an extra back-end method,
+ byte[] toType1(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>
+ - 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.
+ - Fix comment in etc/pqf.properties (claimed that the Type-1
+ "string" attribute was "phrase"). Just a documentation
+ error.
+ - 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.
+ - Recreate last-in-field support
+ - Add srw.resultSet support to the toPFQ() method. I've not
+ attempted this for the toType1() method: Ralph will have to
+ do it.

- Add support for the new "phonetic" relation modifier,
including its mapping in "etc/pqf.properties".
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
