DIGITAL FUTURES
Principles & Best Practice
Eva / Minerva 08/11/2015
Raise issues that will allow to make correct decisions
Raise awareness of issues that can make or break a digital project
Objective:
Considerations of a Digital Project
How to Preserve? Future Uses?
Preservation?
Who’s the Audience?
Access via Internet? How?
What to Scan? All Part?
What is the Project Objective?
Audience Expectations
How complete? Effort?If I build it, will they come?

Best Practice for Standardization
• Archival standards: ISAD(G), ISDIAH, ISAAR-CPF, DACS….
• Digitization (format, PPI)
• File naming
• Long-term digital preservation (LTDP) (OAIS, PREMIS)
• Data exchange: EAD

OAIS (Open Archival Information System) A reference model for long-term preservation of digital assets.
PREMIS (PREservation Metadata: Implementation Strategies)
Archive Network Israel Project
• ISO 1551 (ISIL) - International Standard identifier for archives (link)
• Adoption of ISAD(G), ISDIAH
• EAD for data exchange between archival institutions – EADi
• שותפים - הפרויקט אתר
EADi (EAD-Israel)
Conclusions
• Use accepted standards
• Implement best practices to ensure best possible
• Digitization
• Long-term digital preservation
• Data sharing and exchange
• End-user access
2 ApproachesTake Risks
Don’t take risks
RisksTrademark
Copyright
Privacy
Slander
Ensure status of copyright
Adopt a strategy
Perform due-diligence
Document due-diligence
Get permits, agreements in writing!
Control end user usage
Insurance
Know the law
Know who and when to ask
How do we minimize risk?
“Reasonable people adapt themselves to the world;
Unreasonable people try to change the world to fit their fantasies.
Therefore, all progress is thanks to unreasonable people”
Engage the crowd
User feedback promotes discussion and thinking
So what do we want to know?
• What is the size of the audience?
• Who is the audience?
• Where is the audience?
• How does our audience use its time?
• How much of this time is dedicated toward being our
audience?
• What material interests our audience the most? The least?
Feedback Surveys Work groups Monitor the crowd
