3. 3 Discovery Discovery level metadata Semantic search Accessibility Bit level preservation Availability—dark vs. light archives IPR issues, attribution and licensing Usability Interpretability Data/metadata completeness Sufficiency Data/metadata quality, provenance and relevance Semantic mediation tools Challenges

4. 4 Constraints 4 Technical constraints: relatively minor and will be resolved Sociocultural challenges: large (IPR/licensing, community norms, $)

5. 5 Three major components for a flexible, scalable, sustainable network Member Nodes diverse institutions serve local community provide resources for managing their data retain copies of data Coordinating Nodes retain complete metadata catalog indexing for search network-wide services ensure content availability (preservation) replication services Investigator Toolkit Opportunities—e.g., DataONE
