NDIIPP Preservation Network: Progress, Problems, and Promise
Jim Tuttle, Geospatial Data Librarian
NCSU Libraries
NC Geospatial Data Archiving Project
• Partnership between NCSU Libraries and NC Center for Geographic Information & Analysis
• State and local geospatial content in North Carolina
• Tied to NC OneMap initiative, which provides seamless access to data, metadata, and inventories
• Engage existing state/federal geospatial data infrastructures in preservation
NCSU Libraries
Geospatial data types: Vector data

Today’s geospatial data as tomorrow’s cultural heritage
Future uses of data are difficult to anticipate (as with Sanborn Maps).
NCSU Libraries
Geospatial Data: Risks
• Producer focus on current data• Future support of data formats in question• Shift to web services- and API-based
access• Inadequate or nonexistent metadata• Increasing use of spatial databases for data
management
NCSU Libraries
Different Ways to Approach Preservation
• Technical solutions: How do we archive acquired content over the long term?
• Cultural/Organizational solutions: How do we make the data more preservable—and more prone to be archived—from point of production?
NCSU Libraries
Technical Approach: Progress
• Ingest workflow– Receiving data as is – variety of distribution
methods– Migration of some at-risk formats– Metadata remediation, standardization, and
synchronization– Mechanism for distilling complex objects into
repository ingest items • Repository
– Using DSpace for demonstration purposes– In development: use METS record as dormant item
“brain” within the repository
NCSU Libraries
Organizational Approaches: Progress
• Engaging spatial data infrastructure– Feedback to metadata outreach program– Feedback on adherence to content standards– Involvement of state and local advisory bodies in
project– Viral approach to promoting digital preservation
• Engaging industry– Working with software vendors (e.g, ESRI) – Engaging standards community (Open Geospatial
Consortium)
NCSU Libraries
Changing Thinking
• Web 2.0, web mashups, and AJAX technologies create new opportunities (and challenges)– Looking at static, pre-cut image tiles from
geospatial web services as a preservation target• “Contact fatigue” among local agencies—need to
work with state agencies on coordinated flow of data– Participating in a collaborative multi-agency effort
to routinize content exchange
NCSU Libraries
Learning from the NDIIPP Network
• Maturing thinking about metadata transformations (inspiration from the UIUC/OCLC “hub and spoke” model)
• Leveraging outside expertise in preservation metadata (interactions with Stanford NDIIPP project)
• Discussions about mutual use of tools in ingest workflow (JHOVE, ClamAV, noid, MD5, etc.)
• NDIIPP network creates opportunities for interactions that might not otherwise happen
