  13. 5S Model – Informally • Digital libraries are complex information systems that: • help satisfy info needs of users (societies) • provide info services (scenarios) • organize info in usable ways (structures) • present info in usable ways (spaces) • communicate info with users (streams)

  14. Outline • Problems • Background • Approach • ETANA-DL • ETANA-DL Prototype System • Modeling ETANA-DL • ETANA-DL Services • Analysis • Conclusions • Future Work

  15. Solution – our approach • Applying and extending Digital Library (DL) techniques to solve the following problems: interoperability, making primary data available, data preservation • Modeling archaeological information systems using 5S theory to better understand the domain and design the system and the supported services • Rapidly prototyping DLs that handle heterogeneous archaeological data using componentized frameworks: requirements elicitation, provide useful services.

  17. ETANA-DL • Archaeological Digital Library • Applies and extends the OAI-PMH • Open Archives Initiative Protocol for Metadata Handling • Design considerations • Componentized • Distributed architecture • Extensible • Portable

  18. ETANA Digital Library Core Components - DigBase • DigBase (DB) • Central repository - stores metadata • Union catalog - for the collections in ETANA-DL • Various kinds of digital objects – excavation records, images, text collections, etc. • General services - Search, Browse, Annotate, Recommend, etc. • Archaeology-specific services - artifact analysis, visualizations, artifact interpretation, workflows, etc.

  19. ETANA Digital Library Core Components - DigKit • DigKit (DK) • A suite of tools for collecting and recording archaeological data in the field, that can be used for a new dig • Metadata will migrate to DigBase (DB). • Real-time collaborative archaeology: Metadata in DB will be rapidly available to others.
