V2 METADATA TEAM ACCOMPLISHMENTS:  2000-02
Project users’ needs
Move beyond traditional bibliographic description
Develop V2 data model
Establish functional relationships between entities
Identify attributes for each entity
Incorporate vocabulary control
Facilitate navigation of digital objects
Link to and distinguish between different formats of same work
Connect parts of work to whole
Compile documentation

ACCOMPLISHMENT #1: 
Project Users’ Needs
Based on
Experience with music library users
Discussions with music librarians and music faculty
Reference log from Cook Music Library
Personal experience as musicians

ACCOMPLISHMENT #1: 
Project Users’ Needs
Projections
Find all versions, formats, parts of same work with single or separate search
Differentiate between versions, formats, parts of same work
Navigate digitized objects
View and listen simultaneously

ACCOMPLISHMENT #2: 
Move Beyond Bibliographic Description
Examine, re-think existing contents and structure of MARC records for music
Descriptive metadata
Structural (relational) metadata
Administrative metadata

Descriptive Metadata
Descriptive metadata comprehensive in MARC
V2 uses MARC descriptive metadata but but assigns elements to separate entities

Expand Descriptive Metadata?
Mood descriptors
Associated movie titles
Impressions, captions supplied by users
Sounds like...
Feels like...
Makes me think of…

Structural Metadata Limited
in MARC
Table of contents
Duration
Pagination
URL

Structural Metadata Enhanced
in V2
Movements, acts, scenes, sections
Track timings and descriptions
Page and measure numbers

Administrative Metadata Limited
in MARC
Copyright date
Date MARC record created
Local access restrictions
File format

Administrative Metadata Expanded
in V2
Technical data
Access rights
Preservation data


ACCOMPLISHMENT #2: 
Move Beyond Bibliographic Description
Accept that MARC records offer valuable music metadata, syntax, and standards that can be included, enhanced, omitted
Use MARC data whenever possible

Online Shared Catalog Systems:
OCLC / RLG
Total Bibliographic Records (music)
3 million scores
3.6 million sound recordings
Total Authority Records (music and other)
9.3 million name and name/title headings
.5 million subject headings

ACCOMPLISHMENT #3: 
Develop V2 Data Model
Starting Point -- MARC Records

ACCOMPLISHMENT #3: 
Develop V2 Data Model

ACCOMPLISHMENT #3: 
Develop V2 Data Model
Identify, separate, and relate logical and physical layers of musical works and their physical manifestations: 5 entities
Use appropriate MARC data and develop adequate descriptive, administrative, and structural metadata for each entity

Container-Centered MARC Record 
(2 works in 1 container)

Work-Centered V2 Data Model
(2 works in 1 container)

Comparison of MARC and V2
Record Types

Slide 24

ACCOMPLISHMENT #4: 
Establish Functional Relationships
Between Entities
Based on bindings between:

ACCOMPLISHMENT #5: 
Identify Attribute Set for Each Entity
Descriptive Metadata: assists users in work/object identification for searching and browsing
Structural Metadata: arranges entities into logical and physical divisions
Relational Metadata: connects various types of metadata elements and entities to enable efficient searching, browsing, and navigation
Administrative Metadata: accommodates various managerial concerns, properties of digital objects, access information, intellectual property rights information

Subject Headings
Class Numbers
Instrumentation
Form/Genre
Dates
Languages
Geographical Places
Contributor Roles
Document Types
Notation Types

ACCOMPLISHMENT #7: 
Facilitate Navigation of Work


Structural Bindings Facilitate Navigation of Individual Movements, Sections of Work

Slide 35

Slide 36

Replacing Disjunct Part / Whole Relationships
in MARC Environment

ACCOMPLISHMENT #9: 
Connect Parts to Whole via Work Structure

ACCOMPLISHMENT #10:
Compile Documentation
Data Dictionary
Metadata Mappings
Controlled Vocabulary Lists
Cataloging Guidelines and Tutorial
Bibliography
Articles, Presentations, Reports

V2 METADATA GOALS:
2002-04
Populate database
Implement end-user thesaurus
Resolve (?) questions about whole/part relationships, particularly collective uniform titles and arrangements
Determine practicality of research metadata
Establish acceptable minimal-level record

V2 METADATA GOALS:
2002-04
Test effectiveness of metadata / searching
Examine feasibility of DC, other cross-walks, and reconciliation with FRBR
Assess level of endorsement for V2 metadata schema
Collaborate in creating and sustaining music metadata registry
Contribute to greater music knowledge-base

METADATA QUESTIONS
What are we describing (original or digital?)
Collective uniform titles (Beethoven symphonies)
Arrangements (separate work?)
Functionality of minimal-level records
Value of “query-less” metadata
Subject headings as separate entity
Additional metadata for individual sections, parts of work, printed inserts, photos
