1. North Carolina Geospatial Data Archiving Project/NDIIPP: Collection and preservation of at-risk digital geospatial data Partners: NCSU Libraries NC Center for Geographic Information & Analysis Presenter: Rob Farrell, NCSU Libraries Best Practices Exchange 2006March 27-28, 2005

2. 2 NCGDAP Ingest Workflow Overview Project context Compelling Issues and Guiding Principles Workflow from receipt to ingest Workflow focus: Digital format curatorship Workflow focus: Geospatial metadata management

3. 3 Project Context NDIIPP: National Digital Information Infrastructure and Preservation Program, a Library of Congress collaboration Focus on state and local geospatial content in North Carolina (state demonstration) Tied to NC OneMap initiative, which provides for seamless access to data, metadata, and inventory information

4. 4 Project Context GIS environments Map viewers Geospatial digital object formats NCOneMap Local portals

5. 5 Geospatial Data: Compelling Issues Dynamic content Constantly updated information Minimal versioning standards Digital object complexity Spatially enabled databases Complicated, multi-component formats Proprietary formats

6. 6 Digital Object Complexity

7. 7 NCGDAP Guiding Principles Promoting the NSDI Process integration Outreach Digital curatorship is part of the process Format persistence Incorporating reality Custodianship of the archive Someone has to be responsible Success and failure

8. 8 Workflow Overview Handout 1

9. 9 Workflow Focus: Digital Format Curatorship Handout 2

10. 10 Workflow Focus: Geospatial Metadata Management Handout 3

11. 11 Our Response Raise metadata to minimum level Normalize to a standard Manage “expert” intervention Carry forward original metadata record

12. 12 Raise Metadata to Minimum Level (see handout) Metadata template Create template specific to data provider Automate template application Indicate our curatorship Check for sufficiency of critical elements Correct automation artifacts Review contact information Confirm data/metadata concurrency

13. 13 Normalize to a Standard (see handout) XML format May involve format conversion Standard format for project metadata Specialized profile Allows automation attributes Aligns with international standards ISO 19139 topic categories

14. 14 Manage “Expert” Intervention (see handout) Coordinate geospatial metadata management with: Administrative metadata collection Our own curatorship (see handout) Archive metadata production Logical workflows Automation where possible
