NJ Digital Video Initiative

2

William Paterson (VALE), Rutgers Libraries, and NJEDge were awarded a $1M IMLS Grant to provide funding for a rather unique initiative to support academic video on-demand services.


Digital Video Repository

The portal repository supports:

Learning-on-demand for K-20 educators

Licensed commercial academic videos from companies such as Films Media Group, BioMEDIA and others.

Locally owned and developed academic video

Videos searchable through metadata tags

Statewide authentication and authorization.


Project partners - True collaboration

4

Digital Repository expertise Commercial Video licensing

Project management and budget co-ordination

Hosting, Broadband Infrastructure and video streaming expertise


Instructional Advantages of NJVID

5

• Access to content any time, any place

• Easy to construct clips from multi-videos to create learning objects

• Objects are easily integrated with Blackboard, Sakai or Moodle

• Online students can access the same content as classroom students


Broader Vision of NJViD

6

Collection driven – increase availability of digital video content for education and research

Support all learning organizations—higher ed, libraries, museums, archives, K12 schools

Protect rights of content owners and content users

Form the nucleus of a Statewide Cyber-Infrastructure for digital content management and re-use


Statewide CI – Building blocks

What building blocks do we need? Common structure for Authentication and Authorization

--Durable, standardized, consistent--Restricts access for collection management; coursework; research

--Enables collaboration:

faculty faculty

faculty student(s)student student

university universitymuseum school

Building Blocks of Statewide CI


Statewide CI – Faculty Research Management

Collecting and Managing Faculty Research

Unique information Preserved for long-term availability; audit trail Made widely available for scholarly impact Customized for scholarly and educational workflow

Volatile Information Faculty may want to add, revise, remove

Usefulness often requires additional tools SAS, SPSS, etc. Visualization tools (Grapher, MatLab, etc.) GIS

FEDORA and FEDORA Commons

10

Fedora Commons

a non-profit organization funded by a four year, $4.9M grant from the Gordon and Betty Moore Foundation

to develop the organizational and technical frameworks necessary to effect revolutionary change in how scientists, scholars, museums, libraries, and educators collaborate to produce, share, and preserve their digital intellectual creations.

The Fedora platform is logically divided into four major functional areas that reflect its first principles:

repository services

preservation services

semantic services

enterprise services

http://www.moore.org/


FEDORA capabilities

11

The Digital Object

An open content model expressed as XML

Security: Provision of flexible authentication and policy enforcement using XACML for authorization, using the Sun XACML engine

(eXtensible Access Control Markup Language)

Scalability: provision of support for >10 million objects

Provides encapsulation for management and preservation

Content Recon: reuse of objects including object content being present in any number of contexts within a repository; repurposing of objects allowing dynamic content transformations to fit new presentations requirements

Identifiers: provision of persistent identifiers; unique names for all resources without respect for machine address

Relationships: support for relationships between objects

Interoperable Access: provision of interoperable access by means of a standard protocol to information about objects and for access to object content; discovery and execution of extensible service operations for digital objects


FEDORA capabilities (contd)

12

Repository Services

A service oriented architecture with APIs for access and management

Ontology services for expressing relationships

Messaging, and journaling services

Preservation Services

Audit trails

Versioning

Object integrity – auto checksums

• Insight Media

• Bullfrog

• Discovery Education

• Media In Education

• Alexander Street

• Facets

• Women Make Movies

• VEA

• Icarus

and others….


Commercial Videos – Advantages to Institutions

22

Institutions don’t necessarily need to acquire physical videos anymore

They don’t necessarily need to catalog their licensed videos since another licensing institution may have already done so within NJVid.

Students can access videos from anywhere.

Some vendors without their own portal, such as BioMedia, will be available online for the first time.

Don’t risk providing user accounts to commercial vendors. With Shibboleth we use Institution’s Enterprise Directory for access/deny decisions

This all adds up to reduced staff workload and time spent leading to savings yet providing faculty and staff educational content without worrying about technology

Annotation tool lets faculty, staff and students create learning objects and ultimately create playlists


NJTRUST

23

NJTRUST is New Jersey’s Identity Trust Federation based on Shibboleth

NJVID is the first Service Provider in the Federation

NJTRUST currently has thirteen Identity Providers

LoD Administration hierarchy

26

SCM

ICM

User

Super Collections Manager (SCM) (Statenet level)• Manages all videos, collections and permissions• Can create ICMs

Institutional Collections Manager (ICM)• Manages all videos and collections that belong to his/her institution• Can create users and assign collections to each user• Can view and delete videos by users of his institution• More than one ICM per institution permitted (eg. departmental level). • Manages Labels.

Learning on Demand User• Can upload videos to assigned collections• Manage their own content. Add/delete• Can request access by going to the LoD site• ICM will have to approve access.


LoD Authentication Labels

All videos uploaded into LoD are by default ‘private’. Video can be seen only by uploader.

Labels can be used to enable access to

Institutional role ([email protected] etc) --OR--

NetIDs or UserIDs ([email protected])

A Video can have multiple access labels

Applying the ‘Public’ label makes the video accessible without any authentication.

Access by private URL in the works
