SYNOPSIS

         baseurl  => 'http://localhost:8080/fedora',
         username => 'fedoraAdmin',
         password => 'fedoraAdmin',
         model    => 'Catmandu::Store::FedoraCommons::DC' # default

                    creator => ['Bulgakov, Mikhail'] }
            );

 # Force an id in the store

 my $obj3 = $store->bag->get('demo:120812');
 $store->bag->delete('demo:120812');

     my $pid = $obj->{_id};

DESCRIPTION

A Catmandu::Store::FedoraCommons is a Perl package that can store data into FedoraCommons backed databases. The database as a whole is called a 'store'. Databases also have compartments (e.g. tables) called Catmandu::Bag-s. In Fedora we have namespaces. A bag corresponds to a namespace. The default bag corresponds to the default namespace in Fedora. By default Catmandu::Store::FedoraCommons works with a Dublin Core data model. You can use the add,get and delete methods of the store to retrieve and insert Perl HASH-es that mimic Dublin Core records. Optionally other models can be provided by creating a model package that implements a 'get' and 'update' method.

METHODS

new(baseurl => $fedora_baseurl , username => $username , password => $password , model => $model )

Create a new Catmandu::Store::FedoraCommons store at $fedora_baseurl. Optionally provide a name of a $model to serialize your Perl hashes into a Fedora Commons model.

bag('$namespace')

Create or retrieve a bag. Returns a Catmandu::Bag. Use this for storing or retrieving records from a fedora namespace.

fedora

Returns a low level Catmandu::FedoraCommons reference.
