NAME

PICA::Server - Server that can be searched for PICA+ records

SYNOPSIS

my $server = PICA::Server->new(
    title => "My server",
    SRU => "http://my.server.org/sru-interface.cgi"
);
my $record = $server->getPPN('1234567890');

METHODS

new

Create a new Server. You can specify a title with title and the URL base of an SRU interface with SRU.

getPPN

Get a record specified by its PPN. Returns a PICA::Record object or undef.

cqlQuery

Perform a CQL query. If only one parameter is given, the full XML response is returned and you can parse it with PICA::SRUSearchParser.

If you supply an additional hash with Record and Field handlers (see PICA::Parser) this handlers are used. Afterwards the parser is returned.

UTILITY FUNCTIONS

url_encode

Returns the fully URL-encoded version of the given string. It does not convert space characters to '+' characters. This method is based on CGI::Utils by Don Owens.

url_unicode_encode

Returns the fully URL-encoded version of the given string as unicode characters. It does not convert space characters to '+' characters. This method is based on CGI::Utils by Don Owens.

TODO

Better error handling is needed, for instance of the server is "System temporarily unavailable". PICA::SRUSearchParser should only be created once.
