About Version 3.0 DigiTool Repository DigiTool Deposit DigiTool Ingest DigiTool Metadata Editor DigiTool Resource Discovery DigiTool Collection Management


Repository

Main characteristics:Responsible for storage and management of objects. Stand-alone component with a standard API (Web Services).File storage: local (NFS), remote (URL).Local storage is controlled by storage rules.Metadata storage in “XML boxes” based on the metadata type (e.g., descriptive, technical).Decomposition of compound objects (e.g., METS) to facilitate long term preservation.

Metadata Linking – Detail

PID 1001 MID 10MID 11MID 12

PID 1002MID 11 is shared by 2 Digital Entities PID 1001/1002

Metadata is associated with a digital entity, but not exclusively.

Multiple digital entities can “point” to the same metadata, on a metadata-by-metadata basis.


Storage Management

Storage Groups determine the storage type, i.e., location root and folder break.

Storage Rules determine to which Storage Group a certain object is directed. Storage rules can be based on ingest application, preservation level, administrative unit, file size, MIME type, or a combination of these elements.

Storage Groups and Storage Rules are controlled by the repository administrator.


Deposit Module

of learning objects by instructors.

Designed to support the acceptance of digital object deposits:

of scholarly work from students/professors (e.g., theses, dissertations, etc.).

of special collections by non- staff users (e.g., student, faculty members, outsource) as part of collection creation.


Deposit Module

Approver – serves approvers for the review of the deposits

Consists of three main user interfaces:

Deposit – serves depositors for the deposit of objects

Management – allows the configuration of the deposit workflow, depositor and approver profiles and groups

Deposits are ingested into the Repository only after approval Ingest into the Repository can be:

Automatic when a deposit is approved Via the Ingest module where pre ingest tasks can be

further defined


Deposit Module – Main Features

Manages depositor profiles

Assigns material types to depositors

Controls number of deposits

Assigns depositor to approver

Special descriptive forms for each material type

Imposes submission rules per material type (i.e., up to a certain size, only certain formats)

Status-driven deposit management

Special deposit workflows (wizard) for different material types:


Depositor Interface


New Deposit Activity


Two main functions:

Creation and submission of new ingest activities –bulk and individual

Ingest Module

Monitoring of ingest status (scheduled, running success etc.)

Ingest activities can be initiated directly from the Ingest application or by pre-defined for automatic ingest via the Deposit Module


Ingest Main Functions


One loader, multi transformers

Ingest Architecture

Transformer – take objects and/or metadata as input, and transform it to the Repository digital entity representation.

Ingest activity is a workflow that combines a certain transforming process with pre-ingest tasks, and is followed by the generic loader.

All loads (including batch) are processed as individual digital entities to control loading errors.


Ingest ActivityA typical workflow for submission of Ingest activity:

1. Enter activity name and schedule time for running, select type of transformer and determine the background tasks to run as part of the ingest activity.

2. Order/Select background tasks into a task chain

4. Point to location of files or upload files

5. Submit

3. Select Digital Entity template and select/verify background task parameters


Ingest Activity – File upload


Meditor - Metadata Editor

Descriptive Metadata MARC

Technical metadata

The metadata editor in version 3.0 supports editing of the following metadata types:

Dublin Core (Dublin XML)

Image - NISO Z39.87 for still images (MIX) Text – textmd (NYU - METS-Extension) Audio - Audio Technical Metadata (LOC AMD) Video - Video Technical Metadata (LOC VMD)

Preservation metadata – Based on PREMIS

Rights metadata (EXL) Ability to add local fields to all metadata types

Object History metadata – Based on PREMIS


Metadata Editor — Main Features

Templates (local and server)

A client application that provides tools for the effective management of metadata:

Tag-information

Allows viewing of object while cataloging

Allows browsing between objects, based on relationships

Controlling rights (ownership) to the level of metadata type

Controlling editing rights and record editing history


Metadata Editor: Screen Layout


Resource Discovery – Main FeaturesCollection Management and Personal CollectionsThe new delivery system with four new viewersFlexible indexes that allow:

Inclusion of objects with different descriptive formats (e.g., MARC, DC) in the same index.

Creation of one index for objects owned by different administrative units (i.e., Union Catalog).

Recomposition of compound objects (all manifestations or all pages of a book joined in one result).


Resource Discovery Interface

Persistent ToolbarSearch

Collection Exploration


Resource Discovery: Main Components• Simple Search: search functionality targeted for

novice users

• Advanced Search: search functionality targeted for more experienced users

• Collection exploration

• Object Viewing

• User Registration

• My Space: management of personal data


Simple Search OptionsThe Simple Search is the most basic form of searching DigiTool, carried out as a word search in all fields of the resource. There are several possible ways to conduct a simple search:


Advanced Search Options

An array of options to perform complex keyword searches. Search of several indexes simultaneously, indicating terms relations by Boolean operators and limiting a search by media type or file format.Search in XML tags.


Manifestations

The manifestation list is available from the brief view search results screen by clicking the thumbnail (or ellipsis) and from the full view search results screen.


Delivery DigiTool provides out-of-the-box viewers for:

Single objects

Multi-page objects (METS)

EAD objects

e-Shelf viewer

Text viewer

Viewing Compound Objects - METS


Viewing Compound Objects – EAD


Personal CollectionDesigned to support instructional/educational activities.

Approved users, such as professors or instructors, can load objects in their e-Shelf and arrange them in a folder structure, together with objects from the main repository.

Users can share their personal collections with other users (e.g., students) by publishing the collection and receiving a unique URL.

Shared collection can be linked via a simple URL, and easily embedded in CMS/VLE systems.


Collection Management ModuleThe institution can arrange objects in a hierarchical collection structure.

Staff members use a dedicated web-based interface for creation, management, and publishing of collections.

A collection record can point either to a child collection of records (e.g., Art, Paintings) or can include pointers to specific objects or group of objects.

Each collection record can include title, description, and thumbnail.

Each object can be part of more than one collection.


A collection can be defined with a search command (i.e., logical) or a list of Object PID’s (itemized)

Logical vs. Itemized

A logical collection demands “instantiating” the search command to derive an actual list of objects

The end result of the 2 collection types is a list of records, defined under Collection Management by search query or a list of Object PIDs.

Databases/Units in DigiToolThree types of units exist:

2. Silo Unit is a database that holds the data and configuration for the Web-based Resource Discovery e.g. GEN01

1. Admin Unit is a database that controls the work activity of cataloging, deposit, ingest, etc. for that specific unit only. e.g. DTL01, DTL02

3. System Unit is a database that controls system-related activities such as users, repository, storage and cache e.g. DAT01, REP00, EXT01, VIR01


It is a single institutional repository for consortia or multi-branch academic institutions.

Each unit manages and controls its collections within the common repository.

Patrons search all of the collections via a single resource-discovery interface.

Support for Multi-Administrative Units
