Collection and Preservation of At-Risk Digital Geospatial Data
NCSU Libraries and NCCGIA
National Digital Information Infrastructure and Preservation Program
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)
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
