1 Terms and conditions … libraries, subject terminologies and the web Lorcan Dempsey VP Research OCLC Opening keynote, Dewey EPC meeting, March 16, 2004

5 Focus on the environmental conditions in which terms are used –Prelude … –Collections and … –Digital libraries and … –Finally …

6 Prelude

7 Burn the catalog Electronic catalogs, wherever you go in the academic world, have become a horrible crazy-quilt assemblage of incompatible interfaces and vendor-constrained listings. Working through […] a relatively small collection, you still have to navigate at least five completely different interfaces for searching. Historical epochs of data collection and cataloguing lie indigestibly atop one another. Tim Burke, Swarthmore Im to the point where I think wed be better off to just utterly erase our existing academic catalogs and forget about backwards- compatibility, lock all the vendors and librarians and scholars together in a room, and make them hammer out electronic research tools that are Amazon-plus, Amazon without the intent to sell books but with the intent of guiding users of all kinds to the books and articles and materials that they ought to find, a catalog that is a partner rather than an obstacle in the making and tracking of knowledge. Tim Burke, Swarthmore

10 So … We need to find better ways –of leveraging the accumulated library investment in knowledge organization systems –of demonstrating their value –and of releasing their value in a web environment. (OCLC Research activities)

Many different controlled and local vocabularies Interest in place, time, audience, coverage Many different controlled and local vocabularies Interest in place, time, audience, coverage Small number of established universal schemes.

21 So.. Questions –Warrant –Functional requirements of a general classification system in new environment? Becoming more important: –Mappings –Local control of display and hierarchy for particular user communities –Data distribution –Machine- processable

22 Digital libraries and the web

23 Interconnected library environment More complex library systems environment –ILS, portal, resource sharing, resolver, digital asset management, … More complex institutional systems environment –Learning management system, university portal, local government portal, … Growing use of shared services –Directory, identity management, trust management, …

24 A library portal example Common services Content services Application services Presentation services The User Im looking for something through my librarys portal.

25 Common services Content services Application services Presentation services The User authentication Im looking for something through my librarys portal.

26 Common services Content services Application services Presentation services The User Directory: user profile Im looking for something through my librarys portal.

27 Common services Content services Application services Presentation services The User Query broker Im looking for something through my librarys portal.

28 Common services Content services Application services Presentation services The User Directory: service description Im looking for something through my librarys portal.

29 Wow! I should be able to find what I need in this results list. Common services Content services Application services Presentation services The User Content: results list

30 Id like to get this book. Common services Content services Application services Presentation services The User Request broker

31 Id like to get this book. Common services Content services Application services Presentation services The User Directory: ILL policy

32 Id like to get this book. Common services Content services Application services Presentation services The User Directory: service description

33 Id like to get this book. Common services Content services Application services Presentation services The User Content: circ/ILL system

34 I need this article too. Common services Content services Application services Presentation services The User Request broker

35 I need this article too. Common services Content services Application services Presentation services The User openURL resolver

36 I need this article too. Common services Content services Application services Presentation services The User Directory: local knowledge base

37 I need this article too. Common services Content services Application services Presentation services The User Directory: service description

38 I need this article too. Common services Content services Application services Presentation services The User Content: article

39 Directory: ILL policy Subject attributes Common services Content services Application services Presentation services The User Authentication Directory: user profile Query broker Directory: service description Catalog Request broker Circ/ILL system OpenURL resolver Directory: local knowledge base Article db Terminology service Subject Digital assets

40 Some other examples Query routing (e.g. QuestionPoint) Document routing (e.g e-prints UK)

41 So … Libraries need to manage many types of objects – some of which have subject attributes We will increasingly treat vocabularies and terms as resources in their own right Workflow integration becomes more important – services need to be available where they are needed –Metadata creation –Searching … –Data exchange and terminology services

42 Manage many objects … Then: –information assets were primary objects of interest. –Subjects, etc, were seen as attributes of assets. –Systems built to reflect this. Now: –We manage multiple objects, their representations and relationships: Assets –Works; manifestations; copies Rights Collections Services Terms –Concepts –Names –Places Users …

43 Data assets 1.Objects 2.Collections 3.Services 4.Terms 5.Users 6.Institutions 7.Rights 8.Schemes 9.Rules 10.Version Control 11.Queries Web services Digital library objects! Place, person, subject, genre, …

44 Terms are resources Webulated –URI for concepts, … –Concepts are citable –Build services on top of this –Vocabulary may be manifest through several services E.g. URI for a Dewey number Info:ddc/22/eng// Example services –Mappings –Caption, etc –Navigate hierarchy –Validation –Given a concept, return Authors ISBNs …

45 Integrate with workflow Multiple editing environments Multiple searching environments … Growing interest in distribution of data –Protocol access –Data exchange

48

49 Data assets data services Application services Web services Examples: Discovery environment Editing environment e.g Dspace Name authority service KOS service Object metadata repository Validate Automatic class. Navigation Exchange Mapping

50 The past is another country.. Need to think differently – using terminologies as resources in a distributed network environment calls forward different way of thinking –Making functionality available within multiple workflows –Available through human and machine interfaces

51 So.. Questions –Warrant –Functional requirements of a general classification system in new environment? Becoming more important: –Mappings –Local control of display and hierarchy for particular user communities –Machine-processable –Data distribution –Webulated –A suite of terminology services
