Note: Percentages based on the actual number of respondents to each question 18 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 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 wrapper Ingest 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

Note: Percentages based on the actual number of respondents to each question 21 Content Retention and Transfer Ingest into Dspace 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 22 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 23 Big Problems/Issues Management of data versions over time How 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.)

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
