17. 5S Framework • Developed at Digital Library Research Laboratory (DLRL, Virginia Tech ) • Strong foundation for DL module development • Intuitive as well as formal definitions • Base ideas named with five S’s - streams, structures, spaces, scenarios, societies • Key aspects of DLs precisely defined using one or more of the Ss • Set of metamodels for classes of DLs: minimal, archeological (ETANA), practical, European DL, …

18. Informal 5S & DL 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)

19. 5S Examples

20. ETANA Societies • Historic and pre-historic societies (being studied) • Archaeologists (in academic institutes, fieldwork settings, or local and national governmental bodies) • Project directors • Technical staff (consisting of photographers, technical illustrators, and their assistants) • Field staff (responsible for the actual work of excavation) • Camp staff (e.g., camp managers, registrars, tool stewards) • General public (e.g., educators, learners, citizens)

21. ETANA Societies • Social issues • Who owns the finds? • Where should they be preserved? • What nationality and ethnicity do they represent? • Who has publication rights? • What interactions took place between those at the site studied, and others? What theories are proposed by whom about this?

22. ETANA Scenarios • Life in the site in former times • Digital recording: the planning stage and the excavation stage • Planning stage: remote sensing, fieldwalking, field surveys, building surveys, consulting historical and other documentary sources, and managing the sites and monuments • Excavation • Detailed information is recorded, including for each layer of soil, and for features such as pole holes, pits, and ditches. • Data about each artifact is recorded together with information about its exact find spot. • Numerous environmental and other samples are taken for laboratory analysis, and the location and purpose of each is carefully recorded. • Large numbers of photographs are taken, both general views of the progress of excavation and detailed shots showing the contexts of finds. • Organization and storage of material • Analysis and hypotheses generation and testing • Publications, museum displays • Information services for the general public

23. ETANA Spaces • Geographic distribution of found artifacts • Temporal dimension (as inferred by archaeologists) • Metric or vector spaces • used to support retrieval operations, and to calculate distance (and similarity) • used to browse / constrain searches spatially • 3D models of the past, used to reconstruct and visualize archaeological ruins • 2D interfaces for human-computer interaction

24. ETANA Structures • Site Organization • Region, site, partition, sub-partition, locus, … • Temporal orderings (ages, periods) • Taxonomies • for bones, seeds, building materials, … • Stratigraphic relationships • above, beneath, coexistent

25. ETANA Streams • successive photos and drawings of excavation sites, loci, unearthed artifacts • audio and video recordings of excavation activities and discussions • textual reports • 3D models used to reconstruct and visualize archaeological ruins.

26. Exercise 1 • Forms groups of 2. • Select a digital library you wish to build, improve, or study. • As was done for ETANA, discuss it using the 5S perspective. • Present a summary to the class and lead a discussion.

40. DL Manifesto - 1 • DL Reference Model • In support of the future European Digital Library • Developed by team connected with DELOS (Candela, Casteli, Ioannidis, Koutrica, Meghini, Pagano, Ross, Schek, Schuldt) • Draft 2.2 presented in Frescati, near Rome, June 2006 – 79 pages • Could be integrated with work of DLF, JISC, etc.

46. Both LIS and CS For formal and informal learning Many modules Some for whole courses Most much smaller Can be packaged in various ways To make up a (degree / certificate) program To make up a course sequence For a single course A module to bolster an existing course or training program (at any of varied levels) Modules and Curricula
