======================

ABOUT

This module implements an object-oriented interface for building clients and servers that 
resolve LSIDs and perform metadata queries on LSIDs.


* What's new in this release

This release is based on the specification submitted to the Object Management Group (OMG) and
is not compatible with all previous releases. Clients and authorities based on previous
versions should still interoperate with minimal changes to each.  Most changes involve port types
and the addition of a Services WSDL document that describes how to invoke the authority. Please
see the examples/ for more information.



* IMPORTANT: You need SOAP::MIME 0.55 _AND_ SOAP::Lite 0.60 installed for this release.





* Authority Framework

The Authority framework has been moved to LS::Service and underwent significant
changes. In many cases, crating a SOAP based authority has become easier. See
the examples/ subdirectory for two authority examples.



* Caching

The client stack now caches all metadata, data and WSDL queries. The
default path is stored in /tmp/lsid-client and can be change through
then evironment variable LSID_CACHE_ROOT.

The cache does not support getDataByRange nor is it compatible with
either the Java or Windows resolver caches. This will be remedied in
the next code release. 



* LSID Authority Security
 
Version 1.0.1 of the Perl LSID resolver library and authority
framework provide HTTP Basic authentication for securing
authorities. In order to use this functionality, you must
use the following mod_rewrite configuration directives
in Apache:
 
Alias /authority "/var/www/authority/authority.pl"
                                                                                                                  
<Location /authority>
    SetHandler cgi-script
    Options +ExecCGI
    RewriteEngine on
    RewriteCond %{HTTP:Authorization} ^(.*)
    RewriteRule ^(.*) $1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]
</Location>
 
This is to overcome Apache's automatic consumption of the
authentication headers.
