This area contains sample programs that exercise all three of the APIs supported by this module. The programs for each API are contained in separate subdirectories: net-z3950-zoom -- Test programs using the low-level Net::Z3950::ZOOM API, which is an as-literal-as-possible translation of the ZOOM-C API. You should almost certainly not bother reading these programs: they are for the benefit of the module maintainers. zoom -- Test programs using the object-oriented ZOOM interface, which is a nice, Perlish interpretation of the ZOOM abstract API as documented at http://zoom.z3950.org/api/ net-z3950 -- Test programs using the obsolescent Net::Z3950 interface, which is provided by this distribution as a plug-compatible replacement for the old Net::Z3950 module. There is no reason to use this API unless you are maintaining an existing application that uses Net::Z3950. In general, each sample program exists in a different version in all three directories, under the same name in each. The programs are: zoomtst1.pl -- A direct translation of the "zoomtst1.c" application from the YAZ distribution, except that these versions go on to fetch the records that they find, whereas the C version is satisfied just to get the hit count. zoomtst3.pl -- A direct translation of the "zoomtst3.c" application from the YAZ distribution -- simultaneous search of multiple targets. Pretty cool :-) async.pl -- A slightly cleverer version of "zoomtst3.pl" which takes advantage of the new END element introduced in YAZ 2.1.17 to display each server's records as soon as they have been received, rather than waiting until all servers have finished their jobs as in every previous ZOOM-based multiplexer. update.pl -- Create a new database and add a record to it. In addition, this "sample" directory contains sample records that are used by the test-suite to exercise the update functionality. These are found in the "records" subdirectory. It also provides a CQL-to-PQF mapping file (copied blindly from the one in the YAZ distribution), found in the "cql" directory.
