ENCompass Can…
• Search across disparate collections
• Provide access to digital material
• Store and manage metadata in multiple formats
ENCompass Concepts
• Hierarchical method for arranging data and metadata– Collections– Containers– Objects
• Self-defined metadata structures• Reverse inheritance (“bubble-up”)• Cross-collection searching (mapping)• Collections versus repositories
Repositories vs Collections
• Repository – where the data and metadata is stored; the table space on the server
• Collection – the intellectual grouping/s of the data and metadata
• Each has a “manager” in the System Administration client
We Need To Define…
• The base metadata type– Repository – storage of metadata– Collection – cross-searching of collections
• Mappings (data relationships)
• Searching options (weights and types)
• Default displays in the results list
