simple2zoom - generic Swiss Army Server for proxying between IR standards
-c configFile ] [
-- YAZ-options ] [ listener-address ...
simple2zoom provides a generic gateway between the Z39.50 and SRU/SRW Information Retrieval protocols.
Because it relies on the
ZOOM modules for the server and client funcationality respectively,
because both of these modules are based on the YAZ toolkit,
and because YAZ transparently handles all three standard IR protocols (ANDI/NISO Z39.50,
SRU and SRW),
it can function as a gateway from any and to any of these protocols.
its principle purpose is as a Z39.50 server that proxies requests through to a backend by acting as an SRU client.
The following command-line options govern how the gateway functions:
Specifies that the named configFile should be used to configure the functionality of the gateway: if this option is not specified,
then the file
client.xml is used.
The format of the configuration file is described separately in
and a sample configuration file,
is supplied in the
etc directory of the distribution.
Indicates the end of
This is required if YAZ options are to be specified,
simple2zoom doesn't try to interpret them itself.
Command-line arguments subsequent to the
-- option are interpreted by the YAZ backend server as described at http://www.indexdata.dk/yaz/doc/server.invocation.tkl
These options provide the means to control many aspects of the gateway's functioning: for example,
whether the server forks a new process for each client or runs a single process using
select(); how (if at all) to interpret incoming SRU requests; whether and how to log protocol packets for debugging.
One or more YAZ-style listener addresses may be specified,
and the server will accept connections on those addresses: for example,
If no explicit listener addresses are provided,
the server listens on port 9999.
