DL OverviewWhy of Global Interest?
• National projects can preserve antiquities and heritage: cultural, historical, linguistic, scholarly
• Knowledge and information are essential to economic and technological growth, education
• DL - a domain for international collaboration– wherein all can contribute and benefit– which leverages investment in networking– which provides useful content on Internet & WWW– which will tie nations and peoples together more
strongly and through deeper understanding
Digital Libraries --- Objectives

Informal 5S & DL Definitions
DLs 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)
16
• “Streams”
- All types of contents
(as well as communications and flows over networks, or into sensors, or sense perceptions)
• “Structures”
- Organizational schemes
(including data structures, databases, and knowledge representations – taxonomies, ontologies)
5S Framework
17
5S Framework
• “Spaces” - 2D and 3D interfaces, GIS data,
representations of documents and queries. • “Scenarios”
- System states and events, but also can represent situations of use by human users (or machine
processes, yielding services or transformations of data). • “Societies”
- Both software “service managers” and fairly generic “actors” who could be (collaborating) human (users).

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
27
ETANA Societies
1. Historic and pre-historic societies (being studied)2. Archaeologists (in academic institutes, fieldwork
settings, or local and national governmental bodies)
3. Project directors4. Technical staff (consisting of photographers,
technical illustrators, and their assistants)5. Field staff (responsible for the actual work of
excavation)6. Camp staff (e.g., camp managers, registrars, tool
stewards)7. General public (e.g., educators, learners, citizens)
28
ETANA Societies
• Social issues1. Who owns the finds?
2. Where should they be preserved?
3. What nationality and ethnicity do they represent?
4. Who has publication rights?
5. What interactions took place between those at the site studied, and others? What theories are proposed by whom about this?
29
ETANA Scenarios1. Life in the site in former times2. Digital recording: the planning stage and the excavation stage 3. Planning stage: remote sensing, fieldwalking, field surveys, building
surveys, consulting historical and other documentary sources, and managing the sites and monuments
4. Excavation1. Detailed information is recorded, including for each layer of soil, and for
features such as pole holes, pits, and ditches. 2. Data about each artifact is recorded together with information about its
exact find spot. 3. Numerous environmental and other samples are taken for laboratory
analysis, and the location and purpose of each is carefully recorded. 4. Large numbers of photographs are taken, both general views of the
progress of excavation and detailed shots showing the contexts of finds. 5. Organization and storage of material6. Analysis and hypotheses generation and testing7. Publications, museum displays8. Information services for the general public
30
ETANA Spaces
1. Geographic distribution of found artifacts2. Temporal dimension (as inferred by
archaeologists) 3. Metric or vector spaces
1. used to support retrieval operations, and to calculate distance (and similarity)
2. used to browse / constrain searches spatially
4. 3D models of the past, used to reconstruct and visualize archaeological ruins
5. 2D interfaces for human-computer interaction
31
ETANA Structures
1. Site Organization1. Region, site, partition, sub-partition, locus,
…
2. Temporal orderings (ages, periods)
3. Taxonomies1. for bones, seeds, building materials, …
4. Stratigraphic relationships1. above, beneath, coexistent
32
ETANA Streams
1. successive photos and drawings of excavation sites, loci, unearthed artifacts
2. audio and video recordings of excavation activities and discussions
3. textual reports
4. 3D models used to reconstruct and visualize archaeological ruins.

Digital Objects (DOs)
• Born digital
• Digitized version of “real” object– Is the DO version the same, better, or worse?– Decision for ETDs: structured + rendered
• Surrogate for “real” object– Not covered explicitly in metamodel for a
minimal DL– Crucial in metamodel for archaeology DL

• 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
• Features– 5SGraph loads and displays a metamodel in a structured toolbox.– The structured editor of 5SGraph provides a top-down visual
building environment for the DL designer.– 5SGraph produces syntactically correct 5SL files according to the
visual model built by the designer.
