Collection and Preservation of At-Risk Digital
Geospatial Data NCSU Libraries and NCCGIA

• National Digital Information Infrastructure and
  Preservation Program

2
NDIIPP Project Context

• Partnership between NCSU Libraries and NC Center
  for Geographic Information Analysis
• Cooperative Agreement with Library of Congress as
  part of the National Digital Information
  Infrastructure and Preservation Program (NDIIPP)
• Three year project starting Oct. 2004
• 520,000 funding
• One of eight projects in the first NDIIPP funding
  round Building a Network of Partners

Risk to Geospatial Data

• Producer focus on current data
• Need permanent access as well as digital
  preservation
• Future support of data formats in question
• Need to migrate formats or allow for emulation
• Data failure
• Bit rot, media failure
• Preservation metadata requirements
• Descriptive, administrative, technical, DRM
• Shift to streaming data for access
• Impact on development of secondary archives

NDIIPP Project Phases

• Content Selection and Identification
• Work from NC OneMap Inventory
• Content Acquisition
• Leverage NC OneMap data sharing agreements
• Partnership Building
• Work closely with local/state/federal agencies
• Content Retention and Transfer
• Digital repository (initially Dspace)
• Formulate preservation metadata (using METS)
• Digital rights management (DRM)

8
Project Summary

• Identify available data resources through the NC
  OneMap data inventory
• Acquire at-risk digital geospatial data from
  state, regional, local agencies (and others)
  build time series
• Develop digital repository architecture for
  geospatial data, using open source software tools
  such as Dspace
• Use METS records as a metadata wrapper for data
  files, descriptive/technical metadata, DRM, etc.
• Investigate use of Open Geospatial Consortium
  technologies in data identification and capture
  processes
• Development of a model for data archiving and
  time series development

Key Challenges

• Technical
• Efficient methods for inventory and acquisition
• Formulation of preservation metadata
• Format choices
• Encoding digital rights information (DRM)
• Repository ingest and management
• Organizational
• Securing agreements for data access and transfer
  (including to Library of Congress where
  possible) address concerns about misuse of older
  data
• Promote importance of time series development and
  long term preservation
• Learn from established experience and practice of
  data custodians
