NAME

MOBY::Client::Central - a client side wrapper for MOBY Central

SYNOPSIS

 use MOBY::Client::Central;
 my $Central = MOBY::Client::Central->new();

 my ($Services, $REG) = $Central->findService(
	    input =>[
              [DNASequence => ['NCBI_gi', 'NCBI_Acc']],
                ],
		expandObjects => 1
		);
 unless ($Services){
	 print "Service discovery failed with the following errror: ";
	 print $REG->message;
	 end
 }
 foreach my $SERVICE(@{$Services}){
    print "Service Name: ", $SERVICE->name, "\n";
    print "Service Provider: ", $SERVICE->authority,"\n";

 }

DESCRIPTION

Client side "wrapper" for communicating with the MOBY::Central registry.

Used to do various read-only transactions with MOBY-Central. Parses MOBY::Central XML output into Perlish lists, hashes, and objects. This should be sufficient for most or all MOBY Client activities written in Perl.

METHODS

new

Usage     :	my $MOBY = MOBY::Client::Central->new(Registries => \%regrefs)
Function  :	connect to one or more MOBY-Central
               registries for searching
Returns   :	MOBY::Client::Central object

ENV & PROXY : you can set environment variables to change the defaults.
            By default, a call to 'new' will initialize MOBY::Client::Central
            to connect to the default MOBY Central registry.  The location of
            this registry can be determined by examining the redirect from:
               http://biomoby.org/mobycentral
            If you wish to chose another registry by default, or if you need
            to set up additional connection details (e.g. PROXY) then you may
            set the following environment variables to whatever you
            require:
            MOBY_SERVER  (default http://moby.ucalgary.ca/moby/MOBY-Central.pl)
            MOBY_URI     (default http://moby.ucalgary.ca/MOBY/Central)
            MOBY_PROXY   (no default)

Args      :    user_agent - optional.  The name of your software application
               Registries - optional.
                          - takes the form
                             {$NAME1 => {
                                   URL => $URL,
                                   URI => $URI,
                                   PROXY => $proxy_server},
                              $NAME2 => {
                                   URL => $URL,
                                   URI => $URI,
                                   PROXY => $proxy_server},
                               }
                           - by default this becomes
                           {mobycentral => {
                                URL => 'http://moby.ucalgary.ca/moby/MOBY-Central.pl',
                                URI => 'http://moby.ucalgary.ca/MOBY/Central'}
                            }
Discussion:    Each registry must have a different
               NAME.  If you have more than one
               registry with the same NAME, only
               one will be used.  You can NAME them
               however you please - this is for
               internal reference only.  You will
               make subsequent calls on one or more
               of these registries by NAME, or by
               default on all registries.
Notes     :    BE CAREFUL WITH OBJECT/SERVICE
               REGISTRATION!! YOU WILL REGISTER
               IN EVERY MOBY-CENTRAL YOU HAVE
               NAMED!  If you do not host a MOBY::Central
               database locally, or don't know
               better,then don't use any arguments
               at all, and everything should work
