18	Problems with MARC catalogs Traditional MARC-based online catalogs not ideal for music Large number of works by single author Multiple works in single container Relationships of performers and other fields to works Multiple roles of “authors” Importance of work: uniform titles Not always possible to easily get one version of a work to others Many variant forms of titles Problems with LC subject headings e.g. “Songs (High voice) with orchestra, Arranged” Isolating / sorting by format
19	Variations2 Version 3 Features Scanned score annotation Playlists Access control Encoded scores Themes & incipits Instrumentation searching Timeliner support of local audio
20	Variations2 Version 1.0 Technical Environment Client and server developed in Java Windows and Mac OS X client platforms, Unix (AIX/Linux) server Audio streaming: QuickTime for Java, Darwin Streaming Server Database: IBM DB2, DB2 Text Information Extender Image compression: DjVu from AT&T Labs and Lizardtech XML/MARC/Z39.50 tools: Saxon, Xerces, Jafer, James
21	Variations2 1.0 Communications
22	Usability Usability = ease of use + usefulness Established baseline Usability test of existing Variations system Satisfaction study of Variations users Contextual inquiry Evaluation of usability of Variations2 Prototype interviews Usability tests of preliminary versions Pilot studies Data gathering through satisfaction survey and automated usage logging
23	Future Versions Features to be added Support for new and emerging streaming technologies Support for video Support for supplemental recording materials (e.g., liner notes, booklets) Improved browsing interface Instructional authoring, classroom presentation, and instructional delivery interfaces Web browser interface Course management system (CMS) integration
24	Technical Issues Result set handling, performance XML search engine vs. relational database Unicode fonts Integration with content-based search Repository integration: FEDORA Closer alignment with standards: FRBR, METS, MODS Level of cataloging Copyright, licensing, access control
25	Partners: “Satellite Sites” United States University of Illinois at Urbana-Champaign University of Massachusetts at Amherst Northwestern University United Kingdom Kings College - London Loughborough University University of Oxford Japan Waseda University Evaluation…potential for co-development
26	Variations2 Data Model Appropriate metadata elements attached to each entity Import mapping from MARC Closely related to FRBR International Federation of Library Associations Report on the Functional Requirements of Bibliographic Records, 1997
27	IFLA FRBR Entities
28	Variations2 Data Model
29	Variations2 Structural Metadata: 3 Types Container Structure attached to container objects defines track information, time, and page offsets Work Structure outlines abstract structure of the work (movements, acts, scenes, etc.) Work Bindings associated with instantiations links particular time and page ranges of instantiations represented by media objects to the abstract work structure
30	Work Structure Example <Structure id="1" label="Symphony no. 7 (Ludwig van Beethoven)"> <Section id="2" label="Movement 1"> <Section id="3" label="Introduction"/> <Section id="4" label="Exposition"/> <Section id="8" label="Development"/> <Section id="9" label="Recapitulation"/> <Section id="10" label="Coda"/> </Section> <Section id="5" label="Movement 2 - Allegretto"/> <Section id="6" label="Movement 3 - Presto"/> <Section id="7" label="Movement 4 - Allegro con brio"/> </Structure>
31	Instantiation Bindings Example <StructureBindings structureID="IU/Work/2001"> <Binding nodeRef="3"> <ContentInterval mediaRef="IU/MediaObject/4021" begin="0" end="234975"/> </Binding> <Binding nodeRef="4"> <ContentInterval mediaRef="IU/MediaObject/4021" begin="234975" end="360255"/> </Binding> <Binding nodeRef="8"> <ContentInterval mediaRef="IU/MediaObject/4021" begin="360255" end="468400"/> </Binding> <Binding nodeRef="9"> <ContentInterval mediaRef="IU/MediaObject/4021" begin="468400" end="596229"/> </Binding> …
32	Variations(1) Variations2 builds upon previous work: Variations Production DL of sound recordings (~8000 titles) and scores (~200 titles) in IU Cook Music Library Used for course reserves and general collection access Variations2 = R&D system Variations = production service Content for Variations2 draws upon existing Variations collection
