Policies & Solutions 12:20-12:30 – Q & A 12:30-4pm - Lunch & Post-Workshop

Informational Meeting

3

How do you start a digital preservation policy development initiative?

Who are the key people in your institution to inform and involve?

What are the basic components of a strong digital preservation policy?

What role do campus/institutional stakeholders play in your policies?

How might institutional values impact policy creation?

4

Session 1

1. What is Digital Preservation?2. A Look at Trends in Digital Preservation

The Goal:To understand the evolving landscape of digital preservation requirements and consider the potential investments needed for developing a policy-driven approach to digital preservation.

7

Not to be confused with digitization

8

More than a simple back-up strategy

9

Not as simple as storing things in the Cloud

Though Amazon, Microsoft, Google and now Apple would like you to think so

10

Not an archiving system

11

There has been lots of research into how to preserve digital formats and the applications that create and maintain them.

There have been lots of debates about significant properties and acceptable loss.

Still a lot of research to do, and issues to discuss.

But one thing is clear…

12

…there is no single solution.

“The series of managed activities necessary to ensure continued access to digital materials for as long as necessary.”- Definition from Digital Preservation Coalition

Quick question?

15

Centralized & Distributed Preservation

Full & Bit-level Preservation Preservation Metadata Open Source Solutions Focus on Economies of Scale and

Benefits Roles & Responsibilities Sustainability Standards and Auditing Metrics

16

Centralized Preservation: Preservation activities managed by a single institution Examples:▪ Library of Congress - Chronicling America▪ FCLA Florida Digital Archive – DAITSS▪ OCLC Digital Archive

Distributed Preservation: Preservation activities managed by multiple

institutions replicating and/or geographically locating collections

Examples:▪ LOCKSS▪ MetaArchive Cooperative ▪ Chronopolis▪ DuraCloud

17

“Full” Preservation Focuses heavily on format migration and

normalization (may still preserve the original)▪ Highly concerned with monitoring and intervening

against format obsolescence up-front

Bit-level Preservation Focuses primarily on preserving the original bits▪ Not opposed to format migration but avoids monitoring

up-front and cites long-lived support or convertability of the majority of formats

Many archives doing a bit of both Somewhat of a false dichotomy

18

PREMIS Intellectual Entities (books, articles, databases) Objects (files, bitstreams, formats) Agents (people, organizations, software) Events (actions involving Agents & Objects) Rights (permissions)

Metadata standards are always under development – weigh issues of adoption seriously

19

Open source is a well recognized best practice at this point – real question is: How open?

Why Open source? Avoiding proprietary solutions can guard against

dependencies and sudden loss Open source formats and technologies maximize

communities of support and ensure flexibility and long-lived solutions

Open source approaches dramatically reduce technology costs and can lead to building of expertise

20

Digital preservation needs are great and digital preservation can be costly

Blue Ribbon Task Force on Sustainable Digital Preservation and Access Economies of scale can reduce staff costs Focus on communicating the benefits to the

institution aids in selection and prioritization▪ Prioritization crucial for offsetting costs▪ Define the institutional value of your assets

You don’t have (shouldn’t try) to save everything!

21

Partnering with other institutions to preserve content is becoming more popular Sharing resources and expertise reduces costs Maintains control over institutional assets rather

than handing over responsibility to third parties Consumers also becoming Producers and

Preservers of digital assets

Modularizing the chain of preservation activities (ingest, storage, dissemination) Microservices and interoperability

22

Many grant-funded projects are short-lived or narrowly focused

Institutions have been pressured to just enter the game and hope for the best

Diverse revenue streams becoming essential

Emphasis on collaborationPromoting self-sustaining cost models
