The Digital Landscape is Emerging

Our campuses are home to a large and growing number of
digital landscape activities

For example, at Yale:

A majority of courses have Web based materials

Dozens of substantial digital teaching and research projects are

A half dozen internally and externally funded digital archiving
investigations are underway

New activities are initiated continuously, independently as well as
in conjunction with the Library and IT units

The Digital Landscape Requires
a Campus Infrastructure

Core teaching and research information is captured, analyzed,
presented, published and archived in digital forms

Such activities are expensive

stream results depend upon upstream decisions as
interoperability depends on standards, interfaces and

The digital landscape is still being invented nationwide

This is a key priority for ITS and the Library at Yale

How should a Campus manage its
Institutional Digital Landscape?

How can we balance faculty
driven projects with institutional

To meet immediate needs, faculty
driven projects are
typically light weight and fast moving

But can easily duplicate or dissipate investment

To meet lasting needs, collection
driven projects typically
require up front investment and ongoing curatorial care

Thus costing more but potentially providing lasting value

What standards and practices should we adopt in the face of
continuing technical change to:

Capture audio, image and video formats and more

Manipulate, analyze, publish

Discover and search


We Start by Examining the

Life Cycle of Digital Materials

Full life cycle view encompasses all phases of digital
materials from “cradle to archive.”

Some materials will span the full life cycle, others will
be short lived.

Life spans:

offs: create, use, discard, e.g., instructional

Shared use: create, publish, archive for a time,
discard, e.g., grant sponsored data

Supported Collection: create, publish, archive,
preserve indefinitely at some ongoing cost

The Design of the Digital Landscape is
Informed by a Digital Life Cycle view

The Digital Landscape is made up of a
continuum of support across projects and
throughout the life cycle of digital resources.

Common infrastructure and best practices can
and should support the entire lifecycle of the
range of projects: from one
off as well as
collections oriented projects.

What Digital Landscape Infrastructure will
Best Advance Institutional Goals?

Today’s discussion:

The Digital Life
cycle from the perspective
of faculty projects

Views from both the Yale ITS/AM&T and
Library perspectives

Including profiles of several campus

What is covered by the life cycle

Life span of projects in the digital landscape
(e.g. research projects, instructional

Life cycle of digital objects, the output of
projects (e.g. images, databases, maps)

Life cycle of digital resources such as
presentations of the digital objects (e.g.
custom web sites, classroom applications,
media productions)

What are the phases of

the digital life cycle?

digitize images, collect surveys,
compile databases, produce videos, etc.

web publishing, (e)
article, classroom presentations, multi
media production, etc.

secondary analysis,
replicate, harvest, republish, reproduce

migrate, emulate, archive

Principles of life cycle management:
managing resources at each stage of the
life cycle

Cradle to archive view of management

Digital assets require specific and varying
applications, support, architecture, and
resources at various phases in their life cycle.

Understanding complexities of the life cycle
and costs associated with each phase will
inform the digital landscape design.

Develop a continuum of support throughout
the life cycle to increase participation,
leverage investments, and lower costs.

Why the faculty perspective?

driven digital initiatives are made
up of a wide variety of resources and
support requirements.

driven projects provide an
informative needs
based environment
for developing new approaches to the
digital landscape.

Digital resources from

driven projects

Long life span (Collection):

Statistical datasets generated from a long term survey of
social attitudes and behavior

Large collection of images relating to the history of women
in Ancient Rome

Medium term life span:

Collection of images of US cities for a portfolio on urban
sociology used in classroom teaching

Very large datasets for neuroimaging analysis course

Single use:

Classroom lecture

Interim research application

Not all digital resources are bound
for the preservation phase

Digital resources will differ in the appropriate
length of their life cycle; support for all
stages may not be needed

Some resources that have long term value yet
become ‘digital orphans.’

Look to develop appropriate solutions to:

leverage utility of digital assets

access/reuse assets & productions over time

Example of long term collection

Yale G
Econ Project


Statistical database of global GDP with extensive metadata

Geographic coding and geo

Ability for research team to entering data and metadata

Publish and repurpose

Large scale centralized, web accessible data storage

Sophisticated Web site w/ statistical and GIS applications

Scholarly publications


Manage and provide access over long term

Required by NSF

Support from Social Science Research
Services to G
Econ project

Production phase

Custom data entry front end for distributed staff: enter data
values, formulas, and descriptive metadata

Database design for backend master database for Web
distribution and analysis

Web interface design and implementation

Publication and repurposing phases

GIS web service for interactive GIS visualization

Publication and presentation output (high quality graphics)

Archival concerns

Ongoing maintenance and development

Archival responsibility for the data AND the interface


Production tools

: format and metadata


Development space,

Short, mid, and
long term



Web support

Harvesting/searching tools

publishing solutions


Short, mid, and
long term



Web support

Interoperability, discovery

Web support



Digital projects benefit from early

Efforts in the production stages will reap long
term benefits in the publishing, reuse, and
archiving stages

Infuse best practices into faculty projects:

the choices of format and metadata standards at
the creation of digital resources can significantly
increase both short

and long
term benefits

Provide tools and processes that make best
practices attractive and cost effective at the
design and production phases of the life

Challenges of the life cycle

What is the cost of each life
cycle stage, both initial
and ongoing?

What digital assets should we collect and what are
created for a limited time or purpose?

Who decides what to preserve?

Where do we most effectively provide support and

Which digital assets should be institutionally

Principles might include reuse beyond the author,
e.g., not single use instruction

A Library’s view of faculty
driven digital
projects in teaching with images: ELI

Initiatives [ELI]:

A focused effort to facilitate and study
the use of digital images and other
materials in teaching, learning, and

American Digital Imaging Project

Assessment Techniques

Current observations about goals for
supporting faculty
driven projects in the
digital landscape: ITS

Provide spheres of support and common tools
throughout the flow of digital collection, production,
access, and preservation processes

Build a consistent and efficient infrastructure for
digital assets

Leverage innovation; integrate innovation into
production and infrastructure

Promote an architecture that supports collaboration,
partnerships and effective long term management

Mine and preserve Yale resources

Additional observations about goals for
supporting faculty
driven projects in the
digital landscape: Library

Balance client desires for immediate use of
digital assets & products with institutional
desire for long term availability

Don’t loose perspective of impact of project

Facilitate knowledge management
partnerships to assess teaching,
infrastructure support, and behavior

Foster respect of intellectual property rights


Challenges in the digital landscape

What kind of support and infrastructure are necessary at the
various phases of the life cycle? How much can be centralized,
how much is discipline specific, how much can be ubiquitous?

How do faculty navigate among support units as they move
through the phases, e.g., from production to publishing to

What are the entry costs for each collection level?

How do we develop and promote common standards, best
practices, tools, architecture, and staff expertise across

Can collections from disparate domains be managed w/in
common digital repositories?
