4. Sorting Out the Ingredients Raw materials User interface Elements of organization Building the collection

5. Greenstone New Zealand Digital Library Project at the University of Waikato with UNESCO, Human Info NGO International, every continent Examples: Academic –Digitization projects –Classes on digital libraries Non-academic –UNESCO humanitarian documentation

6. Greenstone features Works with existing documents –Imports several formats Searching: full text and metadata –Dublin Core, custom metadata Browse Structured documents –Indexing, access Extensible & customizable OpenSource software (GPL)

7. User Interface overview Finding documents –Search full text and metadata indexes –Classifiers: browse lists for navigating collections Navigating documents –Navigate hierarchical documents by logical structure –Simple page turning (not shown) –Single page for simple documents (not shown)

19. Greenstone Architecture Receptionist Collection Server DB & Indexes Redrawn from Witten & Bainbridge, How to Build a Digital Library, p. 356 Protocol Collection Import DB & Indexes Collection Import DB & Indexes Collection Import Receptionist

20. Greenstone Architecture Receptionist Provides user interface Accept user input Send to appropriate collection server Accept results Dynamic page generation Collection Server Handle collection content Search and filter information Return results multiple collections

21. DB & Indexes HTML PDF ImportBuild GSAF ??? Building Collections

22. Building collections Create a collection framework –or work with an old collection Select documents Import documents –Converts to internal XML format (GSAF) Build collection –creates search indexes and browse listings

23. GSAF: internal XML format Section: Description –Metadata fields Content –Text,internal markup, images Section –No limit in number or depth Hierarchical documents Sections nest, tree structure

24. [Text, images, links, etc.] … GSAF: internal XML format

25. Config file: collect.cfg Collection-specific configuration file, collect.cfg, specifies: file types to import Indexes and browse lists –Document or section level –paragraph (text index only) display of results and browse listings document displays

31. Chopin Early Editions Over 400 early edition Chopin scores 1830’s to 1880’s Target audience: music scholars & musicians. On web, page-turnable JPEG images. Online in March 2003 Currently 374 scores in online collection Usage: Nearly100 hits per day, > 30% of use is international.

39. Catalog records Scanned Images Structural metadata METS XSLT Greenstone Archive Format Greenstone Dig. Library Software Human processing XML-based automated processing Build overview

46. Ongoing work: Greenstone Greenstone Librarian Interface (GLI) Greenstone 3

47. Greenstone Librarian Interface (GLI) Collection management –Informed by work at GS sites –Assist collection designer –Support all phases of collection build process –Do not specify workflow Java-based GUI tool –Formerly called the “Gatherer” 2 yrs in development –Beta sites: Bangalore and elsewhere Training sessions –UNESCO sessions in Asia, Africa –JCDL 2004 tutorial

48. GLI functions Establish new collection (or work on old) Select files to include in collection Enrich files with metadata Select indexes, classifiers Build collection Customize appearance Preview collection

49. Greenstone 3 GS2 mature, 5+ yrs., wide deployment –Constraints: support legacy systems –Other technologies have matured: Java, XML GS3: rewrite in Java, XML, XSLT Distributed architecture, SOAP METS as internal format –Group assembled for Greenstone METS profile(s) OAI support planned 1 year in dev; alpha testing in lab
