Dspace now; re-ingest to different environment Web services consumption for archival development

Note: Percentages based on the actual number of respondents to each question 15 Rights Issues Various interpretations of public records law 53.9% of local NC agencies charge for data 43.7% of local NC agencies restrict redistribution Desire for downstream control of data Disclaimer clickthrough; liability concerns Filtered locations/individuals; post 9/11 issues Restrictions on redistribution; commercial resale Web services area in “Wild West” stage Both content and technical agreements GeoDRM initiative in the works

Note: Percentages based on the actual number of respondents to each question 16 Big Challenges Management of data versions over time How to “get current object/metadata/DRM”? Relation of the canonical metadata package to the ingest (and export) metadata package Tailor to repository environment or make the acquaintance when needed? Format migration paths (geodatabases, etc.) Dealing with “late-late stage” products The counterpart to the map is not just the dataset— also includes models, symbology, interpretation
