-Revision history for "cql-java"
+Revision history for the "cql-java" package.
See the bottom of this file for a list of things still to do.
-0.3 (IN PROGRESS)
+0.5 (IN PROGRESS)
+ - Change regression-test rules for Adam's compiler to use his
+ new front-end cql2xcql instead of the old cqlparse3.
+ - Fix comment in etc/pqf.properties (claimed that the Type-1
+ "string" attribute was "phrase"). Just a documentation
+ error.
+
+0.4 Thu Nov 21 10:09:26 2002
+ - Add support for the new "phonetic" relation modifier,
+ including its mapping in "etc/pqf.properties".
+ - Make prefix-maps bind loosely, so that ``>dc=x a and b''
+ applies the dc=x binding to both the ``a'' and ``b''
+ sub-queries.
+ - Change the XCQL output to include the nasty (but official)
+ <leftOperand> and <rightOperand> wrapper elements.
+ - Change the XCQL output to use the nasty (but official)
+ rendition of prefix-mapping: a <prefixes> element,
+ containing one of more <prefix>es may appear at the top
+ of either a <searchClause> or a <triple>.
+ - Include test/regression/xmlpp.pl in the distribution: this
+ may now be used for testing whether a CQL compiler produces
+ _equivalent_ XCQL to what's in the regression test, rather
+ than requiring byte-identical output.
+ - Include the reference XCQL output in the distribution, for
+ the regression test suite to run against.
+ - Change build process so that javadoc documentation is built
+ by "make" in the "docs" directory. There's now a top-level
+ makefile that builds the source, runs the test suite and
+ creates the documentation.
+ - Write javadoc comments for CQLRelation and ModifierSet.
+ - Other improvements to javadoc comments (e.g. describe the
+ `config' parameter to the toPQF() method.)
+ - Sort out the licence: I've settled on the LGPL.
+ - Remove the redundant and misleading etc/Grammar file.
+ - Fix up various Maintenance Agency web addresses that have
+ moved in the great ZING-release shake-up.
+
+0.3 Fri Nov 15 12:04:04 2002
- Allow keywords to be used unquoted as search terms.
- Add support for serverChoiceRelation (scr).
- Add support for prefix-mapping, as in
- >dc="http://dublincore.org/ dc.title=fish
+ >dc="http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
and
- >"http://dublincore.org/ title=fish
- ### But the XCQL output may need to be changed depending on
- the result of the ZNG list's deliberations.
+ >"http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
+ The XCQL generated corresponds to Adam's suggested format
+ rather than Rob's, not so much because I prefer it (although
+ I do) as because it's what fell out when I just Coded What
+ Comes Natur'ly. That may need to change, depending on the
+ result of the ZNG list's deliberations.
- Fix the parser to normalise relation modifiers to lower case.
- Fix the CQLParser test harness not to emit an extraneous
blank line at end of XCQL output.
- 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 StreakTokenizer and rolling our own, which we absolutely
+ out StreamTokenizer and rolling our own, which we absolutely
_don't_ want to do.
- - Write javadoc comments for CQLRelation and ModifierSet.
- - Write "overview" file for the javadoc documentation.
+ - 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.
+ - 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.
* Better selection of terms (from a dictionary file?)
* Introduce wildcard characters into generated terms
* Generate multi-word terms
+ * Generate prefix-mappings
