Concerns

• Scale work to meet the growing number of digital
  publications and electronic records in time of
  limited resources
• Ability to preserve those materials so that we
  could demonstrate authenticity and protect
  integrity

5
Technical Goals

• To develop a curatorial rationale that can be
  implemented in software to support an automated,
  integrated workflow to process collections of
  digital publications and records

6
Curatorial Rationale

• Transformation of traditional, paper-based
  practices into the digital arena
• Appraisal
• Acquisition
• Arrangement and description
• Housing and storage
• Reference and access
• Preservation

7
Curatorial Rationale

• Logical, systematic basis for our work
• Evolutionary (reactionary) v. Designed
  (intentional)
• Integrate work done in different, narrowly
  defined areas
• Focus on the rules, not the records
• Automate the rules

8
Technical Goals

• To develop a curatorial rationale that can be
  implemented in software to support an automated,
  integrated workflow to process collections of
  digital publications and images
• To build digital stacks storage that has
  appropriate controls for preservation and
  disaster preparedness

9
Digital Stacks

• More than storing the data (CD, tape, disk)
• LOCKSS
• Automatic integrity checking and error correction
• Secure
• Geographically distributed

10
Additional Goals

• To build a community of shared practice that
  meets the needs of a wide range of repositories
• For best practices
• For resource sharing
• To remove barriers by keeping costs as low as
  possible

11
Assumptions

• Consistency of government records makes it
  possible to simplify processing by focusing on
  common traits
• Volume of records especially at the series
  level make it reasonable to automate processing

12
Consistency Volume

• Brides Name
• Grooms Name
• Marriage Date
• Recording Date
• License Number

• Office of Origin
• Series name
• Location (county)
• OOO Identifier
• Documentary form

• Identify core metadata
• Descriptive standards (content, data values)
• Functional specs for administration, discovery,
  preservation
• Create Accessions Register database
• Develop schemas for AIPs, SIPs, and DIPs
