3 Revision history for the CQL-Java package.
4 See the bottom of this file for a list of things still to do.
6 0.7 Thu Sep 4 22:51:11 2003
7 - Support for profiled relations and relation modifiers:
8 recognise any non-key word as a relation or modifier,
9 rejecting those that are not of the form <prefix>.<name>
10 since these must be explicitly tied to a "context" (what
11 used to be called a qualifier-set or index-set).
13 0.6 Tue Jul 29 23:33:56 2003
14 - Include Ralph's fix for CQLTermNode::toType1BER() to prevent
15 it surrounding multi-word terms in quotes when encoded into
18 0.5 Wed Feb 5 15:50:57 2003
19 - Add an extra back-end method,
20 byte[] toType1BER(Properties config)
21 which generates an opaque BER-encoded PDU suitable for
22 forwarding to Z39.50 server as a pasrt of a searchRequest
23 APDU. This was contributed by Ralph Levan <levan@oclc.org>
24 - Add srw.resultSet support to the toPFQ() method.
25 - Add new resultSetName() method to CQLNode and its
26 subclasses, returning the name of the referenced result-set
27 for a node that is just a result-set reference, and null for
29 - Change regression-test rules for Adam's compiler to use his
30 new front-end cql2xcql instead of the old cqlparse3.
31 - Change the names of the anchoring properties in
32 etc/pqf.properties and the CQLTermNode code that examines
33 them, in accordance with Adam's PQF-renderer's behaviour.
34 This gives more flexibility in terms of generating
35 attributes for end-of-field anchoring. Various other minor
36 tweaks to the pqf.properties file, mostly to the comments.
37 - Change the capitalisation of the project name from
38 "cql-java" to "CQL-Java". That doesn't really make any
39 difference to anything: in particular, file-names such as
40 "cql-java.jar" remain the same.
42 0.4 Thu Nov 21 10:09:26 2002
43 - Add support for the new "phonetic" relation modifier,
44 including its mapping in "etc/pqf.properties".
45 - Make prefix-maps bind loosely, so that ``>dc=x a and b''
46 applies the dc=x binding to both the ``a'' and ``b''
48 - Change the XCQL output to include the nasty (but official)
49 <leftOperand> and <rightOperand> wrapper elements.
50 - Change the XCQL output to use the nasty (but official)
51 rendition of prefix-mapping: a <prefixes> element,
52 containing one of more <prefix>es may appear at the top
53 of either a <searchClause> or a <triple>.
54 - Include test/regression/xmlpp.pl in the distribution: this
55 may now be used for testing whether a CQL compiler produces
56 _equivalent_ XCQL to what's in the regression test, rather
57 than requiring byte-identical output.
58 - Include the reference XCQL output in the distribution, for
59 the regression test suite to run against.
60 - Change build process so that javadoc documentation is built
61 by "make" in the "docs" directory. There's now a top-level
62 makefile that builds the source, runs the test suite and
63 creates the documentation.
64 - Write javadoc comments for CQLRelation and ModifierSet.
65 - Other improvements to javadoc comments (e.g. describe the
66 `config' parameter to the toPQF() method.)
67 - Sort out the licence: I've settled on the LGPL.
68 - Remove the redundant and misleading etc/Grammar file.
69 - Fix up various Maintenance Agency web addresses that have
70 moved in the great ZING-release shake-up.
72 0.3 Fri Nov 15 12:04:04 2002
73 - Allow keywords to be used unquoted as search terms.
74 - Add support for serverChoiceRelation (scr).
75 - Add support for prefix-mapping, as in
76 >dc="http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
78 >"http://www.loc.gov/zing/cql/dc-indexes/" dc.title=fish
79 The XCQL generated corresponds to Adam's suggested format
80 rather than Rob's, not so much because I prefer it (although
81 I do) as because it's what fell out when I just Coded What
82 Comes Natur'ly. That may need to change, depending on the
83 result of the ZNG list's deliberations.
84 - Fix the parser to normalise relation modifiers to lower case.
85 - Fix the CQLParser test harness not to emit an extraneous
86 blank line at end of XCQL output.
87 - Fix CQLNode documentation to contain a link to YAZ's
88 documentation of Prefix Query Format (PQF) rather than
89 containing a rather unhelpful chunk of BNF.
90 - Change the test/regression Makefile so that "make clean" now
91 does what "make distclean" used to do - the distinction
92 between them is pointless.
93 - Fix a few typos in the documentation.
94 - Move the README file's old "THINGS TO DO" section to the end
95 of this file, the new "Still to do" section.
97 0.2 Wed Nov 6 23:05:54 2002
98 - Fix the order of proximity parameters in accordance with the
99 updated official grammar, which now specifies proximity
100 operators of the form
101 prox/<relation>/<distance>/<unit>/<ordering>
102 as in ``foo prox/<=/3/sentence bar''.
103 - Make the necessary parts of the CQLNode class and its
104 subclasses public. This means that client code can now walk
105 through parse-trees and so implement its own back-end
106 (e.g. to build BER-friendly data structures using whatever
107 Z39.50 toolkit is preferred.)
108 - Add the toPQF(Properties p) method to CQLNode and its
109 subclasses. This produces a query in YAZ-style Prefix Query
110 Format, which can be trivially translated into a Z39.50
111 Type-1 query (see, for example, JZKit's code to do so).
112 - Add etc/pqf.properties to configure the toPQF() method.
113 - Add "-p <props-file>" option to the CQLParser test-harness,
114 indicating that the parsed tree is to be rendered to PQF.
115 - Add PQFTranslationException and its subclasses
116 UnknownQualifierException, UnknownRelationException,
117 UnknownRelationModifierException and
118 UnknownPositionException.
119 - Rename ParameterMissingException to MissingParameterException.
120 - Add javadoc comments for CQLNode and its subclasses.
122 0.1 Sun Nov 3 20:58:27 2002
123 - First public release.
128 - Test-harness option to use Type1 BER back-end.
129 - Case-insensitive matching for serverChoice and any other
130 special-case qualifiers. (Are the configured qualifiers
131 matched case-insensitively? They should be.)
132 - Prefix-aware matching for serverChoice, so that
133 >x="http://www.loc.gov/zing/srw/dc-indexes/v1.0/" x.resultSet=foo
134 does the right thing.
135 - Extend test-suite for PQF and BER renderers.
136 - Additional test-suite entries for things like
138 - Add a new configuration file that allows arbitrary new
139 relations and relation modifiers to be defined.
140 - Fix the bug where "9x" is parsed as two tokens, a TT_NUMBER
141 followed by a TT_WORD. The problem here is that I don't
142 think it's actually possible to fix this without throwing
143 out StreamTokenizer and rolling our own, which we absolutely
144 - Fix term-to-PQF translation to omit empty properties
145 (for the broken Korean server)
146 - Write "package.html" file for the javadoc documentation.
147 - Some niceties for the cql-decompiling back-end:
148 * Don't emit redundant parentheses.
149 * Don't put spaces around relations that don't need them.
150 - Many refinements to the random query generator:
151 * Generate relation modifiers
153 * Don't always generate qualifier/relation for terms
154 * Better selection of qualifier (configurable?)
155 * Better selection of terms (from a dictionary file?)
156 * Introduce wildcard characters into generated terms
157 * Generate multi-word terms
158 * Generate prefix-mappings
