OUTLINE F Introduction F Global digital libraries, for education F NDLTD –Overview, History –Members, Collection –Support, Extensions F Building digital libraries F Conclusion

How do universities and digital libraries relate? F Each U. will have its own digital library. Hence there will be large numbers (i.e., critical mass). F All students will learn how to use and how to “feed” digital libraries (and bring those habits to future work as needs and skills). F All digital library problems (esp. federation, flexibility, personalization) appear at U’s (so they are a good type of testbed, with willing collaborators in-place for developing solutions).

OUTLINE F Introduction F Global digital libraries, for education F NDLTD –Overview, History –Members, Collection –Support, Extensions F Building digital libraries F Conclusion

DLs: Why of Global Interest? F National projects can preserve antiquities and heritage: cultural, historical, linguistic, scholarly F Knowledge and information are essential to economic and technological growth, education F 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

Support Offered F Software, documentation, tech support F , listservs - eval, -grad, -library, -technical) F Donations: Adobe, Microsoft F Evaluation: instruments, analysis - solutions/statistics F (Temporary storage / archiving; aid - in setting up an int’l service & archive)

PetaPlex F Digital Library Machine (“super” object store) F Parallel computer / storage utility for scale of 1000 to 1,000,000 gigabytes (terabyte/petabyte) F Knowledge Systems Incorporated is supplying VT-PetaPlex-1 with –high speed backbone connection (OC-12) –2.5 terabytes through 100 “Nanoservers”: –Network connection + IBM 25GB disk MHz Pentium II + Linux

Sornil & Mather Dissertations F VT-PetaPlex-1 delivered, being installed F Mather: efficiently handling very large numbers of objects of varying sizes F Sornil: efficiently handling IR for very large collections, large numbers of users, high transaction rates, large inverted files –modeling and simulation –data organization (partitioning) –parallelization of algorithms, alone and in combination for retrieval (related) tasks

Enhancements F Dublin Core spec, MARC crosswalk F DTDs for SGML, XML(+ ML) F Annotation system (author, friends, notes) F Routing system (based on Sift) F Multilingual WWW site, training materials (Spanish recently done in Valencia) F Better federated search (w. Z39.50, planned with Dienst and Harvest - maybe MARIAN)

MARIAN F Multiple Access Retrieval of Information with Annotations F (Marian the Librarian …) F Evolved from CODER system to a distributed Online Public Access Catalog (OPAC), then DL backend, now becoming a full DL system F From C/C++ to Java F Future: NDLTD, NUDL, PetaPlex

MARIAN Layers Database Layer Search Engine Layer User Information Layer User Interface Layer User

Relationship with publishers F Concern of faculty and students that still wish to publish books or journal articles, voiced: campus, Chronicle, NPR, Times F Solution: Approval Form gives students, faculty choices on access, when to change access condition; use IPR controls in DL F Solution: by case, work with publishers and publisher associations to increase access – AAP, AAUP – AAAS, ACM, ACS, Elsevier,...

Some responses from publishers F ACM: need to acknowledge copyright F Elsevier: need to acknowledge copyright F IEEE-CS: endorse initiative F ACS: After first publication, can release F Textbook publishers: different market, manuscript significantly reworked F General: restricting access to local campus will not cause any problems

For Professional Societies F Like “writing across the curriculum” F Besides writing: computing/communications, information literacy, personal digital library management, tool use, research methods, collaboration, archiving/preservation F Data sets, communities of users of them F Classification systems / browsing / searching F NRC’s “On becoming a researcher”

OUTLINE F Introduction F Global digital libraries, for education F NDLTD –Overview, History –Members, Collection –Support, Extensions F Building digital libraries F Conclusion

How to Build a Digital Library F Understand the problem (using the 5S Framework) F Solve the problem (using the Star Methodology) –design, develop, evaluate, –refine, operate

5S Layers Societies Scenarios Spaces Structures Streams

Definition: Digital Libraries are complex systems that F help satisfy info needs of users (societies) F provide info services (scenarios) F organize info in usable ways (structures) F present info in usable ways (spaces) F communicate info with users (streams)

Definition: 5S Framework F Societies: interacting people (, computers) F Scenarios: services, functions, operations, methods F Spaces: domains + constraints (e.g., distance, adjacency): 2D, vector, probability F Structures: relations, trees, nodes and arcs F Streams: sequences of items (text, audio, video, network traffic) F (5 Element System: Fire, Wood, Earth, Metal, Water)

5S: Components F Societies: roles, rituals, reasons, relationships, artifacts F Scenarios: acquire, index, consult, administer, preserve F Spaces: physical, temporal, functional, presentational, conceptual F Structures: architectures, taxonomies, schema, grammars, links, objects F Streams: granularities, protocols, paths, flows, turbulences

5S: Combinations F Societies + Scenarios = user model F Societies + Scenarios + Spaces = user interface F Streams + Structures = markup F Streams + Structures + Scenarios = object F Structures + Scenarios = DBMS

Star Methodology

Neill Kipp Dissertation F Training interested groups about 5S and the Star Methodology, refining the Framework to have solid mathematical foundation F Case studies of projects at Virginia Tech or involving VT staff/students: CSTC, NDLTD, NARA (National Archives, with SAIC), Lexis,... F Open also to study DL projects elsewhere F Focusing too on the design artifacts developed and related issues of efficient description and representation (esp. with markup, hypermedia)
