Metadata harvesting OAI: Data & Service Providers Service Providers Discovery Current Awareness Preservation Data Providers
Data and Service Providers • Data Providers • possess metadata and share it (internally / externally) • via well-defined OAI protocols (e.g., database servers) • Service Providers • harvest and preserve data from Data Providers • provide higher-level services to users • (e.g., search engines) • Who will fit where in ETANA-DL? • Data Provider – YOUR PROJECT • Service Provider – ETANA-DL
OCKHAM • Simplicity (a la OCCAM’s razor) • Support by Mellon and DLF • Four main ideas: • Components • Lightweight protocols • Open reference models (e.g., 5S, OAIS) • Community perspective and involvement • Funded by NSF in NSDL, with P2P
Reference Models • Reference Model: a common vocabulary and description of components, services, and inter-relationships that comprise a system under consideration • Useful as a tool to foster consensus and common understanding in a time of rapid change and/or disagreement
Informal 5S DefinitionsDLs are complex 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)

5SGraph: A DL Modeling Tool • Overall objective of 5SGraph: Help users model their own instances of a digital library (DL) in the 5S language (5SL). • A simple modeling process which enables rapid generation of digital libraries is needed. • Support non-expert users. • Speed-up development process. • Increase the quality of final product.
Overview of 5SGraph Workspace (instance model) Structured toolbox (metamodel)
ETANA-DL Approach • Applying and extending Digital Library (DL) techniques to solve key problems: making primary data available, data preservation, and interoperability • Modeling archaeological information systems using 5S to better understand the domain and design the system and the supporting services • Rapidly prototyping DLs that handle heterogeneous archaeological data using componentized frameworks: • eliciting requirements • refining metamodel and union schema • modeling sites • mapping • harvesting • providing useful services
