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