Long-Term Preservation of At- Risk Digital Geospatial Data: A Cooperative Agreement with Library of Congress Steve Morris NCSU Libraries Zsolt Nagy NC Center for Geographic Information & Analysis

Note: Percentages based on the actual number of respondents to each question 2 Project Context Partnership between NCSU Libraries and NC Center for Geographic Information & Analysis $520,000 funding Focus on state and local geospatial content in North Carolina (state demonstration) Address NC OneMap objective: “Historic and temporal data will be maintained and available.” One of eight projects in the first NDIIPP funding round: “Building a Network of Partners”

Note: Percentages based on the actual number of respondents to each question 3 Targeted Content Resource Types GIS “vector” (point/line/polygon) data Digital orthophotography Digital maps Tabular data (e.g. assessment data) Content Producers Mostly state, local, regional agencies Some university, not-for-profit, commercial Selected local federal projects

Note: Percentages based on the actual number of respondents to each question 5 Risks to Digital Geospatial Data Producer focus on current data Archiving data does not guarantee “permanent access” 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

Note: Percentages based on the actual number of respondents to each question 10 Earlier NCSU Acquisition Efforts NCSU University Extension project Target: County/city data in eastern NC “Digital rescue” not “digital preservation” Project learning outcomes Confirmed concerns about long term access Need for efficient inventory/acquisition Wide range in rights/licensing Need to work within statewide infrastructure Acquired experience; unanticipated collaboration

Note: Percentages based on the actual number of respondents to each question 11 Exploring Approaches to Sharing Data County and City GIS Directories

Note: Percentages based on the actual number of respondents to each question 12 Content Identification and Selection Work from NC OneMap Data Inventory Combine with inventory information from various state agencies and from previous NCSU efforts Develop methodology for selecting from among “early,” “middle,” and “late” stage products Develop criteria for time series development Investigate use of emerging Open Geospatial Consortium technologies in data identification

Note: Percentages based on the actual number of respondents to each question 13 Content Acquisition Work from NC OneMap Data Sharing Agreements as a starting point (the “blanket”) Secure individual agreements (the “quilt”) Investigate use of OGC technologies in capture Use METS (Metadata Encoding and Transfer Standard) as a metadata wrapper Bundle data files, metadata, ancillary documentation Supplement FGDC metadata with additional administrative, technical, and descriptive metadata Encode rights (Digital Rights Management – DRM) Links to services

Note: Percentages based on the actual number of respondents to each question 14 Partnership Building Work within context of the NC OneMap initiative Explore state, local, federal partnerships Defined characteristic: “ Historic and temporal data will be maintained and available” Advisory Committee drawn from the NC Geographic Information Coordinating Council subcommittees Seek external partners National States Geographic Information Council FGDC Historical Data Committee … more

Note: Percentages based on the actual number of respondents to each question 15 Content Retention and Transfer Ingest into Dspace open source digital repository software Look more generically at the issue of putting geospatial content into digital repositories Investigate re-ingest into a second platform Start to define format migration paths Special problem: geodatabases Purse long term solution Roles of data producing agencies, state agencies; NC OneMap; NCSU

Note: Percentages based on the actual number of respondents to each question 16 End of Project Outcomes Components which become part of state geospatial data infrastructure NC OneMap objectives for long term access Start a dialog about digital preservation; create stories about digital preservation that can be told in geospatial industry venues Components which NCSU Libraries continues for its own business reasons High user demand for local data, historical versions Components which are not sustainable

Note: Percentages based on the actual number of respondents to each question 17 Areas for Collaboration and Partnership Identifying data for inclusion in the repository Sharing inventories of data holdings Discussing data format strategies Sharing ideas about archiving approaches and architectures Discussing strategies for preservation of geodatabase contents Sharing and identifying concerns about rights issues, liability, etc.
