Earlier Acquisition Efforts
NCSU University Extension project 2000-2001
Target: County/city data in eastern NC“Digital rescue” not “digital preservation”
Project learning outcomesConfirmed concerns about long term accessNeed for efficient inventory/acquisitionWide range in rights/licensingNeed to work within statewide infrastructureAcquired experience; unanticipated collaboration

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
![Page 19: Project Context](https://reader035.fdocuments.net/reader035/viewer/2022081513/56813a27550346895da20b46/html5/thumbnails/19.jpg)
Note: Percentages based on the actual number of respondents to each question 19
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 as a metadata wrapperIngest FGDC metadata (crosswalk to MODS?)
Maybe METS DRM short term; GeoDRM long term
Consider PREMIS elements (extract from FGDC?)
Consider links to services; version management

State expression of the National Map
Defined characteristic: “Historic and temporal data will be maintained and available”Advisory Committee drawn from the NC Geographic Information Coordinating Council subcommittees
Seek external partnersNational States Geographic Information Council FGDC Historical Data Committee

Content Retention and Transfer
Ingest into DspaceLook more generically at the issue of putting geospatial content into digital repositories
Investigate re-ingest into a second platform
Start to define format migration pathsSpecial problem: geodatabases
Purse long term solutionRoles of data producing agencies, state agencies; NC OneMap; NCSU

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
![Page 23: Project Context](https://reader035.fdocuments.net/reader035/viewer/2022081513/56813a27550346895da20b46/html5/thumbnails/23.jpg)

Big Problems/Issues
Management of data versions over timeHow to “get current object/metadata/DRM” from a given data object?
Relation of the canonical metadata package to the ingest (and export) metadata package for a particular repository environment
Tailor the canonical package to the repository environment or make the acquaintance when needed?
Format migration paths (geodatabases, etc.)
![Page 24: Project Context](https://reader035.fdocuments.net/reader035/viewer/2022081513/56813a27550346895da20b46/html5/thumbnails/24.jpg)
Note: Percentages based on the actual number of respondents to each question 24
Big Problems/Issues (Continued)
Preserving relational databases
Role of persistent identifiers
Semantic issues (data attributes, etc.)
Viability of web services consumption as an archive development approach
Getting data sharing agreements to cover preservation use cases
Relation of DRM statement & rights for current object to older versions of object
