DESCRIPTION

Catmandu::Store::File::FedoraCommons is a Catmandu::FileStore implementation to store files in a Fedora Commons 3 server. Each Catmandu::FileBag.

METHODS

new(%connection_parameters)

Create a new Catmandu::Store::FedoraCommons. The following connection parameters can be provided:

baseurl: The location of the Fedora Commons endpoint. Default: http://localhost:8080/fedora

user: The username to connect to Fedora Commons

password: The password to connect to Fedora Commons

namespace: The namespace in which all bag identifiers live. Default: demo

dsnamespace: The namespace used to create new data streams. Default: DS

md5enabled: Calculate and add a MD5 checksum when uploading content. Default: 1

versionable: Make data streams in Fedora versionable. Default: 0

purge: When purge is active, deletion of datastreams and records will purge the content in FedoraCommons. Otherwise it will set the status to 'D' (deleted). Default: 0

model

When a model is set, then descriptive metadata can be added to the File::Store folders. Only one type of model is currenty available 'DC'. Examples:

    $ cat record.yml
