3 Revision history for the CQL-Java package.
4 See the bottom of this file for a list of things still to do.
6 0.6 Tue Jul 29 23:33:56 2003
7 - Include Ralph's fix for CQLTermNode::toType1BER() to prevent
8 it surrounding multi-word terms in quotes when encoded into
11 0.5 Wed Feb 5 15:50:57 2003
12 - Add an extra back-end method,
13 byte[] toType1BER(Properties config)
14 which generates an opaque BER-encoded PDU suitable for
15 forwarding to Z39.50 server as a pasrt of a searchRequest
16 APDU. This was contributed by Ralph Levan <levan@oclc.org>
17 - Add srw.resultSet support to the toPFQ() method.
18 - Add new resultSetName() method to CQLNode and its
19 subclasses, returning the name of the referenced result-set
20 for a node that is just a result-set reference, and null for
22 - Change regression-test rules for Adam's compiler to use his
23 new front-end cql2xcql instead of the old cqlparse3.
24 - Change the names of the anchoring properties in
25 etc/pqf.properties and the CQLTermNode code that examines
26 them, in accordance with Adam's PQF-renderer's behaviour.
27 This gives more flexibility in terms of generating
28 attributes for end-of-field anchoring. Various other minor
29 tweaks to the pqf.properties file, mostly to the comments.
30 - Change the capitalisation of the project name from
31 "cql-java" to "CQL-Java". That doesn't really make any
32 difference to anything: in particular, file-names such as
33 "cql-java.jar" remain the same.
35 0.4 Thu Nov 21 10:09:26 2002
36 - Add support for the new "phonetic" relation modifier,
37 including its mapping in "etc/pqf.properties".
38 - Make prefix-maps bind loosely, so that ``>dc=x a and b''
39 applies the dc=x binding to both the ``a'' and ``b''
41 - Change the XCQL output to include the nasty (but official)
42 <leftOperand> and <rightOperand> wrapper elements.
43 - Change the XCQL output to use the nasty (but official)
44 rendition of prefix-mapping: a <prefixes> element,
45 containing one of more <prefix>es may appear at the top
46 of either a <searchClause> or a <triple>.
47 - Include test/regression/xmlpp.pl in the distribution: this
48 may now be used for testing whether a CQL compiler produces
49 _equivalent_ XCQL to what's in the regression test, rather
50 than requiring byte-identical output.
51 - Include the reference XCQL output in the distribution, for
52 the regression test suite to run against.
53 - Change build process so that javadoc documentation is built
54 by "make" in the "docs" directory. There's now a top-level
55 makefile that builds the source, runs the test suite and
56 creates the documentation.
57 - Write javadoc comments for CQLRelation and ModifierSet.
58 - Other improvements to javadoc comments (e.g. describe the
59 `config' parameter to the toPQF() method.)
60 - Sort out the licence: I've settled on the LGPL.
61 - Remove the redundant and misleading etc/Grammar file.
62 - Fix up various Maintenance Agency web addresses that have
63 moved in the great ZING-release shake-up.
65 0.3 Fri Nov 15 12:04:04 2002
66 - Allow keywords to be used unquoted as search terms.
67 - Add support for serverChoiceRelation (scr).
68 - Add support for prefix-mapping, as in
69 >dc="http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
71 >"http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
72 The XCQL generated corresponds to Adam's suggested format
73 rather than Rob's, not so much because I prefer it (although
74 I do) as because it's what fell out when I just Coded What
75 Comes Natur'ly. That may need to change, depending on the
76 result of the ZNG list's deliberations.
77 - Fix the parser to normalise relation modifiers to lower case.
78 - Fix the CQLParser test harness not to emit an extraneous
79 blank line at end of XCQL output.
80 - Fix CQLNode documentation to contain a link to YAZ's
81 documentation of Prefix Query Format (PQF) rather than
82 containing a rather unhelpful chunk of BNF.
83 - Change the test/regression Makefile so that "make clean" now
84 does what "make distclean" used to do - the distinction
85 between them is pointless.
86 - Fix a few typos in the documentation.
87 - Move the README file's old "THINGS TO DO" section to the end
88 of this file, the new "Still to do" section.
90 0.2 Wed Nov 6 23:05:54 2002
91 - Fix the order of proximity parameters in accordance with the
92 updated official grammar, which now specifies proximity
94 prox/<relation>/<distance>/<unit>/<ordering>
95 as in ``foo prox/<=/3/sentence bar''.
96 - Make the necessary parts of the CQLNode class and its
97 subclasses public. This means that client code can now walk
98 through parse-trees and so implement its own back-end
99 (e.g. to build BER-friendly data structures using whatever
100 Z39.50 toolkit is preferred.)
101 - Add the toPQF(Properties p) method to CQLNode and its
102 subclasses. This produces a query in YAZ-style Prefix Query
103 Format, which can be trivially translated into a Z39.50
104 Type-1 query (see, for example, JZKit's code to do so).
105 - Add etc/pqf.properties to configure the toPQF() method.
106 - Add "-p <props-file>" option to the CQLParser test-harness,
107 indicating that the parsed tree is to be rendered to PQF.
108 - Add PQFTranslationException and its subclasses
109 UnknownQualifierException, UnknownRelationException,
110 UnknownRelationModifierException and
111 UnknownPositionException.
112 - Rename ParameterMissingException to MissingParameterException.
113 - Add javadoc comments for CQLNode and its subclasses.
115 0.1 Sun Nov 3 20:58:27 2002
116 - First public release.
121 - Test-harness option to use Type1 BER back-end.
122 - Case-insensitive matching for serverChoice and any other
123 special-case qualifiers. (Are the configured qualifiers
124 matched case-insensitively? They should be.)
125 - Prefix-aware matching for serverChoice, so that
126 >x="http://www.loc.gov/zing/srw/dc-indexes/v1.0/" x.resultSet=foo
127 does the right thing.
128 - Extend test-suite for PQF and BER renderers.
129 - Additional test-suite entries for things like
131 - Add a new configuration file that allows arbitrary new
132 relations and relation modifiers to be defined.
133 - Fix the bug where "9x" is parsed as two tokens, a TT_NUMBER
134 followed by a TT_WORD. The problem here is that I don't
135 think it's actually possible to fix this without throwing
136 out StreamTokenizer and rolling our own, which we absolutely
137 - Fix term-to-PQF translation to omit empty properties
138 (for the broken Korean server)
139 - Write "package.html" file for the javadoc documentation.
140 - Some niceties for the cql-decompiling back-end:
141 * Don't emit redundant parentheses.
142 * Don't put spaces around relations that don't need them.
143 - Many refinements to the random query generator:
144 * Generate relation modifiers
146 * Don't always generate qualifier/relation for terms
147 * Better selection of qualifier (configurable?)
148 * Better selection of terms (from a dictionary file?)
149 * Introduce wildcard characters into generated terms
150 * Generate multi-word terms
151 * Generate prefix-mappings
