Net::Z3950::SimpleServer 1.03

Net::Z3950::SimpleServer is a simple Perl API for building Z39.50 servers. SYNOPSIS use Net::Z3950::SimpleServer; sub my_search_handler { my $args = shift; my $set_id = $args->{SETNAME}; my @database_list = @{ $args->{DATABASES} }; my $query = $args->{QUERY}; ## Perform the query on the specified set of databases ## and return the number of hits: $args->{HITS} = $hits; } sub my_fetch_handler { # Get a record for the user my $args = shift; my $set_id = $args->{SETNAME}; my $record = fetch_a_record($args->{OFFSET}); $args->{RECORD} = $record; if (number_of_hits() == $args->{OFFSET}) { ## Last record in set? $args->{LAST} = 1; } else { $args->{LAST} = 0; } } ## Register custom event handlers: my $z = new Net::Z3950::SimpleServer( INIT => &my_init_handler, CLOSE => &my_close_handler, SEARCH => &my_search_handler, FETCH => &my_fetch_handler); ## Launch server: $z->launch_server("ztest.pl", @ARGV); The SimpleServer module is a tool for constructing Z39.50 "Information Retrieval" servers in Perl. The module is easy to use, but it does help to have an understanding of the Z39.50 query structure and the construction of structured retrieval records. Z39.50 is a network protocol for searching remote databases and retrieving the results in the form of structured "records". It is widely used in libraries around the world, as well as in the US Federal Government. In addition, it is generally useful whenever you wish to integrate a number of different database systems around a shared, asbtract data model. The model of the module is simple: It implements a "generic" Z39.50 server, which invokes callback functions supplied by you to search for content in your database. You can use any tools available in Perl to supply the content, including modules like DBI and WWW::Search. The server will take care of managing the network connections for you, and it will spawn a new process (or thread, in some environments) whenever a new connection is received..
