3 Revision history for "cql-java"
4 See the bottom of this file for a list of things still to do.
7 - Allow keywords to be used unquoted as search terms.
8 - Add support for serverChoiceRelation (scr).
9 - Add support for prefix-mapping, as in
10 >dc="http://dublincore.org/ dc.title=fish
12 >"http://dublincore.org/ title=fish
13 ### But the XCQL output may need to be changed depending on
14 the result of the ZNG list's deliberations.
15 - Fix the parser to normalise relation modifiers to lower case.
16 - Fix the CQLParser test harness not to emit an extraneous
17 blank line at end of XCQL output.
18 - Fix CQLNode documentation to contain a link to YAZ's
19 documentation of Prefix Query Format (PQF) rather than
20 containing a rather unhelpful chunk of BNF.
21 - Change the test/regression Makefile so that "make clean" now
22 does what "make distclean" used to do - the distinction
23 between them is pointless.
24 - Fix a few typos in the documentation.
25 - Move the README file's old "THINGS TO DO" section to the end
26 of this file, the new "Still to do" section.
28 0.2 Wed Nov 6 23:05:54 2002
29 - Fix the order of proximity parameters in accordance with the
30 updated official grammar, which now specifies proximity
32 prox/<relation>/<distance>/<unit>/<ordering>
33 as in ``foo prox/<=/3/sentence bar''.
34 - Make the necessary parts of the CQLNode class and its
35 subclasses public. This means that client code can now walk
36 through parse-trees and so implement its own back-end
37 (e.g. to build BER-friendly data structures using whatever
38 Z39.50 toolkit is preferred.)
39 - Add the toPQF(Properties p) method to CQLNode and its
40 subclasses. This produces a query in YAZ-style Prefix Query
41 Format, which can be trivially translated into a Z39.50
42 Type-1 query (see, for example, JZKit's code to do so).
43 - Add etc/pqf.properties to configure the toPQF() method.
44 - Add "-p <props-file>" option to the CQLParser test-harness,
45 indicating that the parsed tree is to be rendered to PQF.
46 - Add PQFTranslationException and its subclasses
47 UnknownQualifierException, UnknownRelationException,
48 UnknownRelationModifierException and
49 UnknownPositionException.
50 - Rename ParameterMissingException to MissingParameterException.
51 - Add javadoc comments for CQLNode and its subclasses.
53 0.1 Sun Nov 3 20:58:27 2002
54 - First public release.
59 - Fix the bug where "9x" is parsed as two tokens, a TT_NUMBER
60 followed by a TT_WORD. The problem here is that I don't
61 think it's actually possible to fix this without throwing
62 out StreakTokenizer and rolling our own, which we absolutely
64 - Write javadoc comments for CQLRelation and ModifierSet.
65 - Write "overview" file for the javadoc documentation.
66 - Some niceties for the cql-decompiling back-end:
67 * Don't emit redundant parentheses.
68 * Don't put spaces around relations that don't need them.
69 - Consider the utility of yet another back-end that translates
70 a CQLNode tree into JZKit's representation of a Type-1 query
71 tree. That would be nice so that CQL could become a JZKit
72 query-type; but you could achieve the same effect by
73 generating PQF, and running that through JZKit's existing
74 PQN-to-Type-1 compiler.
75 - Many refinements to the random query generator:
76 * Generate relation modifiers
78 * Don't always generate qualifier/relation for terms
79 * Better selection of qualifier (configurable?)
80 * Better selection of terms (from a dictionary file?)
81 * Introduce wildcard characters into generated terms
82 * Generate multi-word terms
