-Compilation and installation
-
-The primary output of the source here is the libyaz.a library, which
-contain support functions for implementing the server or client role
-of Z39.50/SR. Currently, the library is placed in a directory 'lib'
-which is one level *above* the distribution directory (yaz). This was
-initially done because the library is often used along with several
-other packages, and it was useful to gather the different libraries in
-a common place. If you don't like it, changing the 'LIBDIR' macro in
-the toplevel makefile should be sufficient. Obscurely, the header
-files are located in the include-directory *under* the yaz/ directory.
-
-The toplevel makefile also contains directions on how to enable Peter
-Furniss' XTIMOSI package. The package can be downloaded from
-ftp://pluto.ulcc.ac.uk/ulcc/thinosi/... (or something close to that).
-If you place the xtimosi directory on the same level as the yaz
-directory, and simply follow the directions in the toplevel YAZ
-makefile, the libmosi.a library from xtimosi should link in with no
-problems. The xtimosi library is needed to support a full OSI stack,
-but is *not* required to talk to American-style Z39.50 implementations
-over TCP/IP. Don't worry about compiling the test applications in the
-xtimosi package. Just do a "make libmosi.a", and do whatever is
-required to make the compilation complete on your local ystem.
-
-Two test-programs of interest are generated when you type 'make' at
-the top level. server/ztest and yazlib/cli. Ztest is a dummy database

+The primary output of the source here is the lib/libyaz.a library,

+role of Z39.50/SR.
+
+Windows programmers: refer to the file windows.txt which describes
+how to compile the software using Microsoft Visual C++.
+
+On Unix, GNU configure is used to configure YAZ and generate Makefiles.
+Type "./configure", then "make" to build YAZ.
+
+Two test-programs of interest are generated when you type 'make' at the
+top level: ztest/ztest and client/client. Ztest is a dummy database
server which returns canned responses to all queries. It's good for
verifying that the protocol works ok, and ztest.c shows a minimalistic
implementation of the 'backend' interface.
-Cli is a linemode Z39.50 client. It supports a fair amount of the
-functionality of Z39.50v2/SR, but some things you need to enable by
-recompilation. Its primary purpose is to excersise the package, and
-verify that the protocol works OK. It can be started by typing
+Client is a linemode Z39.50 client. It supports a fair amount of the

+disable by recompilation. Its primary purpose is to excersise the
+package, and verify that the protocol works OK. It can be started
+by typing
-cli tcp:<hostname>:<port>
+client tcp:<hostname>:<port>
at the UNIX prompt, to connect to a Z39.50 server, or
-cli osi:[<tsel>'/']<hostname>:<port>
+client osi:[<tsel>'/']<hostname>:<port>
+
+to connect to an OSI SR target (this requires mOSI-support). To connect
+to the DANBIB test target, you might use:
+
+client osi:0103/find2.denet.dk:4500
+
+Use '?' to get a list of the available commands.
+
+The current query language for the find command is a bit awkward, but
+functional:
+
+query ::= ['@attrset' <attribute-set>] rpn
+rpn ::= complex | simple | attr rpn
+complex ::= operator rpn rpn
+operator ::= '@and' | '@or' | '@not' | '@prox' proximity
+simple ::= term | set.
+term ::= <word> | '"' <term> ... '"'.
+set ::= '@set' <setname>.
+attr ::= '@attr' [<attribute-set>] <number> '=' <number>.
+proximity ::= exclusion distance ordered relation which unit
+exclusion ::= '1' | '0' | 'void'
+distance ::= <number>
+ordered ::= '1' | '0'
+relation ::= <number>
+which ::= 'known' | 'private'
+unit ::= <number>
+
+Eg.:
-to connect to an OSI SR target (this requires XTIMOSI). To connect to
-the DANBIB test target, you might use:
+Andersen
-cli osi:0103/find2.denet.dk:4500
+"Hans Andersen"
-CLI supports CCL-queries, with the mapping between qualifiers and
-attribute values specified in the file default.bib in the working
-directory.
+@and @attr 1=1 andersen @attr 1=4 @attr 4=2 duckling
+
+@attrset Bib-1 @and @attr GILS 2=2008 Washington @attr 1=21 weather
+
+The sort command takes a sequence of sort specifications. A sort
+specification holds a field (sort criteria) and is followed by flags.
+If the sort critieria includes = it is assumed that the sort SortKey
+is of type sortAttributes using Bib-1. The integer before the = is
+the attribute type and the integer following the = is the attribute
+value. If no = is in the SortKey it is treated as a sortfield-type
+of type InternationalString. Flags observed are s (sort case
+sensitive), i (sort case insensitive), < (ascending), > (descending).
+Eg.:
+ 1=4 i< (use is title, insensitive, ascending).
+ Title s> (String Title, sensitive, descending).
