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.

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
NJViD Presentation – Internet2 FMM - November 2, 2010
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
NJViD Presentation – Internet2 FMM - November 2, 2010
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 facultyfaculty student(s)student student
university university museum school
Building Blocks of Statewide CI
NJViD Presentation – Internet2 FMM - November 2, 2010
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 Commonsa 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:

FEDORA capabilities
11
The Digital ObjectAn open content model expressed as XMLSecurity: 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 preservationContent 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

Commercial Videos – Advantages to Institutions
22
Institutions don’t necessarily need to acquire physical videos anymoreThey 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 decisionsThis all adds up to reduced staff workload and time spent leading to savings yet providing faculty and staff educational content without worrying about technologyAnnotation tool lets faculty, staff and students create learning objects and ultimately create playlists

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.
NJViD Presentation – Internet2 FMM - November 2, 2010
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
