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 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 cli tcp:: at the UNIX prompt, to connect to a Z39.50 server, or cli osi:['/']: to connect to an OSI SR target (this requires XTIMOSI). To connect to the DANBIB test target, you might use: cli osi:0103/find2.denet.dk:4500 CLI supports CCL-queries, with the mapping between qualifiers and attribute values specified in the file default.bib in the working directory. The directories: doc - Documentation. Check this out if you'd like to use the code. util - Various little utility functions. Logging, memory debugging, primitive ISO2709 presentation for the client, etc. odr - Open Data Representation. This module implements the BER encoding rules. Documentation is found in the files odr.man and odr.txt. asn - This module implements the Z39.50/SR protocol. The best way to find out how it works is to look in the sample client/server code in server/seshigh.c or yazlib/tst.c. yazlib - This module primarily implements the transport transparency stack (COMSTACK). The comstack implements a generic interface for exchanging BER-encoded records over a network. It supports the American mode of exchanging the records straight over TCP/IP, and uses Peter Furniss' XTIMOSI package over RFC1006. Look for documentation in the file comstack.man. server - This is the implementation of the server frontend. It It provides event-handling and server managament functions, and calls the backend primitives (best documentation of these is in the file include/backend.h). rfc1006 - Xtimosi requires an implementation of the OSI transport with an XTI-based API. Some systems (HP and DEC, notably) provide this. For others, we provide an implementation of the RFC1006 protocol (which is what ISODE-based implementations typically use). This module is not neeeded if you don't use xtimosi. include - The various header files. makelib - This is a simple utility that gathers the libraries from the previous modules into libyaz.a. lib - The libraries. Primarily libyaz.a.
