NAME
PICA::Store - CRUD interface to a PICA::Record storage
SYNOPSIS
use PICA::Store;
$server = PICA::Store->new( SOAP => $baseurl, $userkey, $password, $dbsid );
%result = $server->get( $id );
%result = $server->create( $record );
%result = $server->update( $id, $record, $version );
%result = $server->delete( $id );DESCRIPTION
This class provided a simple retrieve-insert-update-delete - interface to a record store. Currently there is only a CBS webcat SOAP-API but you could also wrap for instance a Jangle interface with this class.
A formal description of the CBS webcat SOAP-API can be found at http://cws.gbv.de/ws/webcatws.wsdl.
METHODS
new ( $type => $url, %params )
Create a new Server. You must specify at least a connection type and a base URL. Other parameters are userkey, password, and database id. The optional language parameter (default: "en") for error messagescan be one of "de", "en", "fr" or "ne".
Currently only the connection type "SOAP" is supported with limited error handling.
get ( $id )
Retrieve a record by ID.
Returns a hash with either 'errorcode' and 'errormessage' or a hash with 'id', 'record', and 'version'. The 'record' element contains a PICA::Record object.
create ( $record )
Insert a new record. The parameter must be a PICA::Record object.
Returns a hash with either 'errorcode' and 'errormessage' or a hash with 'id', 'record', and 'version'.
update ( $id, $record, $version )
Update a record by ID, updated record (of type PICA::Record), and version (of a previous get, create, or update command).
Returns a hash with either 'errorcode' and 'errormessage' or a hash with 'id', 'record', and 'version'.
delete ( $id )
Deletes a record by ID.
Returns a hash with either 'errorcode' and 'errormessage' or a hash with 'id'.
INTERNAL METHODS
_soap_query ( $operation, @params )
Internal method to prepare, perform and evaluate a SOAP request. Returns a hash with 'errorcode' and 'errormessage' or a hash with 'dbsid', 'id', 'record', and 'version' depending on the type of query. Do not directly call this method.
