3 The Net::Z3950::ZOOM, ZOOM and Net::Z3950 modules
4 =================================================
6 This distribution contains three Perl modules for the price of one.
7 They all provide facilities for building information retrieval clients
8 using the standard Z39.50 and SRW/U protocols, but do so using
11 - If you are new to this distribution, then you should use the ZOOM
12 API, and ignore the others. It is the cleanest, most elegant and
13 intuitive, and most closely follows the letter as well as the spirit
14 of the Abstract ZOOM API as specified at http://zoom.z3950.org/api/
16 - If you have used the old Net::Z3950 module and have to maintain an
17 application that calls that API, then you will want to use the
18 Net::Z3950 classes provided in this distribution, which provide an
19 API compatible with the old module's implemented on top of the new
22 - You should definitely not use the Net::Z3950::ZOOM API, which is not
23 object-oriented, and instead provides the thinnest possible layer on
24 top of the ZOOM-C functions in the YAZ toolkit. This API exists
25 only in order to have ZOOM API built on top of it.
30 To install this module type the following:
40 To build Debian packages issue:
47 This module requires these other modules and libraries:
49 - The YAZ toolkit for Z39.50 and SRW/U communication. This is
50 available as a package on several platform -- for example, Debian
51 GNU/Linux supports "apt-get install yaz". For others, you will need
52 to download and build the source-code, which is much more
53 straightforward that you probably expect. You can get it from
54 http://indexdata.com/yaz/
56 NOTE THAT THE ZOOM-Perl MODULE ABSOLUTELY REQUIRES RELEASE 2.0.11 OR
57 BETTER OF THE YAZ TOOLKIT. You need version 2.1.17 or better if you
58 want to run clever asynchronous programs that use the END event,
59 which did not exist prior to that release.
