Overview

4

• Flexible Extensible Digital Object

Repository Architecture

• A system that serve digital content repository for a wide variety of users– E.g. institutional repository, digital archive, content

management system, scholarly publishing enterprises, and digital library.

• Sponsor by Fedora Common– A non-profit organization providing free product

What is Fedora

fedora-commons.org, wikipedia.org

5

• Fedora has a core component that response to enable durable storage and access to the digital content

• Fedora is able to be either a stand-alone server or a component of other system

• To complete repository solution, 3rd parties are needed to enhance features– E.g. authoring, search engine, workflow management,

security component

Capability

fedora-commons.org

6

• Fedora’s Digital Object Model– The model can apply to many domains and digital object types.

• Distributed Repositories– It can integrated access to digital resource from other repositories.– It provides interface accessed by multiple repositories.

• Preservation & Archiving– Represent preservation object by XML format– Offer content versioning– Can define object to object relationships– Log event history for every change of the object

• Web Service– Provide SOAP and REST access

• Easy to integrate with other applications and systems– It is able to function as a generic repository that other applications or systems can

apply it

Design advantages

fedora-commons.org

7

• Store all types of content and its metadata• Digital content of any type can be managed and maintained• Metadata about content in any format can be managed and maintained• Scale to millions of objects• Access data via Web APIs (REST/SOAP)• Provide RDF search (SPARQL)• Rebuilder Utility (for disaster recovery and data migration)• The entire repository can be rebuilt from the digital object and content files.• Content Model Architecture (define "types" of objects by their content)• Many storage options (database and file systems)• JMS messaging (your apps can "listen" to repository events)• Web-based Administrator GUI (low-level object editing)• OAI-PMH Provider Service• GSearch (fulltext) Search Service• Multiple, customer driven front-ends.

Features

fedora-commons.org

8

• Fedora– A flexible system that is based on fundamental of SOA. It is capable to

preserve and access any types of digital contents. However, it does not provide rich user interface.

• DSpace– A complex system that complete all function of repository focusing on

user experience mainly. However, it is not a flexible system.• EPrints

– A system that is primarily used for scientific publication (digital object are not modified very often). Commonly, it provides features as a document management system.

FOXML

Fedora Object XMLFOXML is a metadata that is stored in an object as a content.FOXML is required by Fedora Repository

13

• Digital Object Identifier: A unique, persistent identifier for the digital object. • System Properties: A set of system-defined descriptive properties that is

necessary to manage and track the object in the repository. – Object Properties describe the object’s type, its state, the content model to which it

subscribes, the created and last modified dates of the object, and its label.

• Datastream(s): The element in a Fedora digital object that represents a content item.

Object Data Model

fedora-commons.org

System Properties

<foxml:objectProperties> <foxml:property NAME="http://www.w3.org/1999/02/22-rdf-syntax-ns#type" VALUE="FedoraObject"/> <foxml:property NAME="info:fedora/fedora-system:def/model#state" VALUE="A"/> <foxml:property NAME="info:fedora/fedora-system:def/model#label" VALUE="FOXML Reference Example"/> <foxml:property NAME="info:fedora/fedora-system:def/model#contentModel" VALUE="TEST_IMAGE"/> <foxml:property NAME="info:fedora/fedora-system:def/model#createdDate" VALUE="2004-12-10T00:21:58.000Z"/> <foxml:property NAME="info:fedora/fedora-system:def/view#lastModifiedDate" VALUE="2005-01-20T22:46:07.506Z"/> <foxml:extproperty NAME="http://www.openarchives.org/OAI/1.1/oai-identifier.xsd" VALUE="oai:cornell.edu:demo:999"/></foxml:objectProperties>

• The content of System Properties is generated by system

For example

15

• A datastream is the element of Fedora object• A Fedora object can have one/more Datastreams– (It can treat as bitstream)

• Fedora model supports versioning of Datastreams– Every change of datastreams has running version

Datastreams

fedora-commons.org

16

• Datastreams can be:– Digital resource that is needed to preserve– Metadata of the digital resource

E.g. DublinCore (DC), METS, PREMIS, …. , and etc

• More …– DC is a default Datastream of Fedora system– AUDIT is to record change of digital object.

• AUDIT content is controlled by system (no human editable)– RELS-EXT is to provide relationship between digital objects

Datastreams

fedora-commons.org

17

• Easy perspective– Fedora repository as a warehouse– Fedora digital object as a cabinet– Datastreams as a drawer

• Datastream Identifier: an identifier for the Datastream that is unique within the digital object (but not necessarily globally unique)

• State: the Datastream state of Active, Inactive, or Deleted• Created Date: the date/time that the Datastream was created

(assigned by the repository service)• Modified Date: the date/time that the Datastream was modified

(assigned by the repository service)• Versionable: an indicator (true/false) as to whether the repository

service should version the Datastream. By default the repository versions all Datastreams.

• Label: a descriptive label for the Datastream• MIME Type: the MIME type of the Datastream (required)

Datastream’s Properties

fedora-commons.org

27

• Format Identifier: an optional format identifier for the Datastream. Examples of emerging schemes are PRONOM and the Global Digital Format Registry (GDRF).

• Alternate Identifiers: one or more alternate identifiers for the Datastream. Such identifiers could be local identifiers or global identifiers such as Handles or DOI.

• Checksum: an integrity stamp for the Datastream which can be calculate using one of many standard algorithms (MD5, SHA-1, etc.)

• Bytestream Content: the "stuff" of the Datastream is about (such as a document, digital image, video, metadata record)


fedora-commons.org

28

• Control Group: pertaining the the bytestream content, a new Datastream can be defined as one of four types, or control groups, as follows:– Internal XML Metadata – To store XML content– Managed Content – To store content that need to preserve; such

as, image file, video, pdf, and etc that upload to the system.– Redirect Referenced Content - To store URL of digital object from

external repository– External Referenced Content – Same purpose as Redirect, but

when user access the content, user will see url of content in the same domain name of the repository

63

islandora

• Institution– University of Prince Edward Island's Robertson Library

• Description– Islandora is an open source project underway at the Robertson Library at the University of

Prince Edward Island. Islandora combines the Drupal and Fedora software applications to create a robust digital asset management system that can be used for any requirement where collaboration and digital data stewardship, for the short and long term, are critical.

• Tools– Fedora Repository + GSearch, Drupal, and Solr

• Link– http://islandora.ca

Overview

example from fedora-commons.org

http://islandora.ca/



64

islandora

• Provide administration panel– View, ingest, and purge any digital objects– Help user to understand the relationship between digital objects

• Provide lightning-fast search of the Fedora database– Including full-text search– Integrate with Solr to be better performance of searching

• Support many formats of metadata – Allow user to define metadata model for each digital object category

• Support many types of digital object– Support collection of both bond-digital and digitized materials

• Drupal Servlet Filter– The Drupal Servlet Filter allows the Fedora Repository to use Drupal’s database for authentication,

including integration with Drupal user roles.• The islandora Module

– The Islandora module is a Drupal module written to allow the Drupal content management system to act as a front end to a Fedora Digital Repository. The module enables viewing and management of Fedora objects. This includes insert, update, and delete datastream, and also browse and search.

• Enabling Indexing/Searching with SOLR– Islandora utilizes the Solr open-source search platform to enable flexible and configurable indexing

and searching. Solr uses the Lucene Java search library at its core for full-text indexing and search and offers hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling as additional features.

• GSearch– The Fedora Generic Search Service, or GSearch, is a search service installed with Fedora that allows

for automatic updating of the Lucene/Solr index. GSearch relies on JMS to receive messages that are sent when Fedora objects are ingested, modified or purged. This keeps the Lucene index in sync with the Fedora repository.

Objective

95

• DURASPACE, a Fedora-DSpace integration, becomes a complete archival repository solution. Users still experiences with the system from rich features that enhance from strong points of DSpace. Furthermore, advantageous back-end features of Fedora are improved in order to serve enhanced DSpace functions.

• Therefore, DURASPACE is capable to provide: – Rich experiences to user; such as,

• rich administration functions, • rich search functions supporting semantic search

– Excellence back-end system that • is based on flexible service architecture • fully supports preservation activities • support versioning of digital object and datastream• has flexible information model appending semantic technology to support relationship

between digital object

• To ensure longevity and re-use of digital content

Fedora with DSpace

Benefits

96

• Identify high impact scholarly applications to integrate with other repositories• Demonstrate DSpace running on top of Fedora• Define common information model

– Map the information model of DSpace to Fedora – Define a common information model for intuitional repository purpose

• Define common standard protocol for repositories• Define scenario for integration open repositories• Develop shared services/modules to enable exchange of information among

repositories• Define common storage API• Integrate semantic technology• Share user interface approaches by Manakin (enhanced DSpace XMLUI) and

build lightweight applications on top of repositories• Move toward common architecture based on well-defined design pattern

DuraCloud

DURACLOUD from duraspace.org

98

• A hosted service and opend technology developed by DuraSpace under concept “Store and Do More”.

• DuraCloud will let libraries and institutes manage own repositories without building own technical infrastructure. It offers storage across commercial and non-commercial provider.

• Progress : Pilot phase• Benefits

– “Digital contents are stored in the cloud”– “Backing up, preserving, and updating content yourself can be an uphill battle”– “Maintaining several copies in different locations is a lot safer”– “Let you add image viewing and media streaming services to your site without messing with new

servers or software”

• PREMIS– PREservation Metadata:

Implementation Strategies– Focus on developing metadata for use in digital

preservation– Sponsored by Library of Congress (LOC)– Objectives

• To store technical information that supports making decision and action in order to do preservation

• To document actions taken, such as migration.• To record the effects of preservation strategies• To ensure authenticity of digital resources over the long-term• To note information about collection management and rights management
