5 Compilation and installation instructions for YAZ
6 $Id: README,v 1.35 2001-04-06 12:26:45 adam Exp $
8 The primary output of the source here is the lib/libyaz.a library,
9 which contains support functions for implementing the server or client
12 Windows programmers: refer to the file windows.txt which describes how
13 to build the software using Microsoft Visual C++.
15 On Unix, GNU configure is used to configure YAZ and generate Makefiles.
16 Type "./configure", then "make" to build YAZ.
18 Note: If you are using the CVS snapshot of YAZ you must have autoconf,
19 automake and libtool installed. Before running configure, create
20 support files by running buildconf.sh in the top-level directory of YAZ.
22 Two test-programs of interest are generated when you type 'make' at the
23 top level: ztest/yaz-ztest and client/yaz-client. Ztest is a dummy
24 database server which returns canned responses to all queries. It's good
25 for verifying that the protocol works ok, and ztest.c shows an
26 implementation of a 'backend' interface.
28 yaz-client is a linemode Z39.50 client. It supports a fair amount of the
29 functionality of Z39.50v2/SR, but some things you need to enable or
30 disable by recompilation. Its primary purpose is to excersise the
31 package, and verify that the protocol works OK. It can be started by
34 yaz-client tcp:<hostname>:<port>[/<database>]
36 at the UNIX prompt, to connect to a Z39.50 server.
38 Use '?' to get a list of the available commands.
40 The current query language for the find command is a bit awkward, but
43 query ::= ['@attrset' <attribute-set>] rpn
44 rpn ::= complex | simple | attr rpn
45 complex ::= operator rpn rpn
46 operator ::= '@and' | '@or' | '@not' | '@prox' proximity
47 simple ::= term | set.
48 term ::= <word> | '"' <term> ... '"'.
49 set ::= '@set' <setname>.
50 attr ::= '@attr' [<attribute-set>] <number> '=' <number>.
51 proximity ::= exclusion distance ordered relation which unit
52 exclusion ::= '1' | '0' | 'void'
56 which ::= 'known' | 'private'
65 @and @attr 1=1 andersen @attr 1=4 @attr 4=2 duckling
67 @attrset Bib-1 @and @attr GILS 2=2008 Washington @attr 1=21 weather
69 The sort command takes a sequence of sort specifications. A sort
70 specification holds a field (sort criteria) and is followed by flags.
71 If the sort critieria includes = it is assumed that the sort SortKey
72 is of type sortAttributes using Bib-1. The integer before the = is
73 the attribute type and the integer following the = is the attribute
74 value. If no = is in the SortKey it is treated as a sortfield-type
75 of type InternationalString. Flags observed are s (sort case
76 sensitive), i (sort case insensitive), < (ascending), > (descending).
78 1=4 i< (use is title, insensitive, ascending).
79 Title s> (String Title, sensitive, descending).
85 util - Various little utility functions. Logging, memory debugging,
86 primitive ISO 2709 presentation for the yaz-client, etc. You'll
87 find the ASN.1 Compiler for YAZ here as well (yc.tcl).
89 odr - Open Data Representation. This module implements the BER
90 encoding rules. Documentation is found in the files odr-use.man
93 z39.50 - This module implements the Z39.50 protocol. This module
94 does the same job as the old 'asn' module except that the source
95 files are auto-generated using an YAZ' ASN.1 Compiler (yaz-comp).
97 zutil - This module implements a collection of Z39.50 utilities, such
98 as query parsing, EXTERNAL handling, etc.
100 ill - This module implements the ISO ILL protocol.
102 comstack - This module implements the transport transparency
103 stack (COMSTACK). The comstack implements a generic interface
104 for exchanging BER-encoded records over a network. It supports
105 the 'American' mode of exchanging the records straight over
106 TCP/IP, and uses Peter Furniss' XTIMOSI package over RFC1006.
107 Look for documentation in the file comstack.man.
109 rfc1006 - Xtimosi requires an implementation of the OSI transport
110 layer with an XTI-based API. Some systems (HP and DEC,
111 notably) provide this. For others, we provide an
112 implementation of the RFC1006 protocol (which is what
113 ISODE-based implementations often use). This module is not
114 needed if you don't use xtimosi, and it's not included in the
117 server - This is the implementation of the server frontend. It
118 provides event-handling and server managament functions,
119 and calls the backend primitives (best documentation of these
120 is in the file include/yaz/backend.h).
122 client - A demonstration client. If we come upon a good design for a
123 higher level client API, that will live here.
125 ztest - A demonstration server that implements a backend.
127 include/yaz - The various header files.
129 lib - The libraries. Primarily libyaz.a. The makefile gathers the
130 libraries from previous modules into libyaz.a.
132 asn - Obsolete - replaced by the codecs in directory z39.50.
133 This module implements the Z39.50 protocol and is only provided
134 for backwareds compatibility.

138 We maintain a mailing-list for the purpose of announcing new versions of
139 the software, bug-reports, discussion etc. You can sign up by sending
140 mail to yaz-request@indexdata.dk and include the following command
