Bibliographic Control of Music Materials Session 4 Metadata, classification, search strategies
Basically… data about data or information that describes another set of data (the library catalog is the best example of metadata) Metadata
Metadata also show the relationships between the elements within the data itself, similar to authority control and access. metadata
Dublin Core refers to a metadata standard for describing digital objects (including webpages) to enhance visibility, accessibility and interoperability (the ability to exchange and use information) But in the library world, catalogers may also use it to describe print objects. Dublin core
There are 15 optional metadata elements, any of which could be repeated or omitted. Dublin Core Metadata Element Set as seen in OCLC Connexion Dublin core
The Dublin Core Metadata Initiative recently added the use of element qualifiers which identify the source of the controlled data. For example… <meta name=“DC.Subject scheme=“LCSH”> Authority control/metadata
So…..how does this relate to music cataloging? Metadata, with its unique identifiers will (hopefully) be able to bring together the 21st century’s many manifestations of music: scores sound recordings visual materials software digital files music metadata
Metadata and Digital Music It is important to describe music in ways that machines can understand Building meaningful descriptions of music that are easy to maintain Exploiting these descriptions to build efficient music access systems that help users find music in large music collections
Metadata and Digital Music According to François Pachet (Sony Music, Paris), there are 3 types of Musical Metadata: Editorial Metadata—obtained from the editor) (e.g. album information, CDDB or Gracenote-) Cultural Metadata—obtained from user profiles (e.g. Amazon) Acoustic Metadata—obtained by an analysis of the audio file (e.g. tempo, rhythm, percussivity, instrument recognition)
Music is classified and organized differently than other materials Wide variety of physical formats Classified by form/genre rather than “aboutness” e.g. trumpet music, hymnals, etc. Music classification
Library of Congress Classification M Mis for works of music ML is for books about music (Music Literature) MT is for materials on teaching music (Music Teaching or Music Theory) Music classification
The call number M is broken down this way: M1-M3.3 Collections M5-M1490 Instrumental Music M1495-M5000 Vocal Music Music classification
M1-M3 Music Collections M1000-M1490 Larger ensembles M56-M176 Solo instrument M1497-M1998 Secular vocal music M180-M298 Duets M1999-M2199 Sacred vocal Music M300-M386 Trios M400-M486 Quartets M500-M586 Quintets M600-M686 Sextets …etc. Music classification
Library of Congress Classification Web makes it very simple… Cutter numbers follow the classification number Music classification
The Library Corporation has a great explanation…. http://www.tlcdelivers.com/tlc/crs/cutr0001.htm Library of Congress Cutter Table Music classification
ANSCR (Alpha-Numeric System for Classification of Recordings) In the Library catalog, the call number for a compact disc is a series of letters and numbers in four groups. Each group is called a "term". What an ANSCR call number looks like: On the computer: B MOZA MF A20 On the label of the item: B (Term 1--Type of music) MOZA (Term 2--Composer or performer) MF (Term 3--Title of work or album) A20 (Term 4--Performer or Label Number)
ANSCR (Alpha-Numeric System for Classification of Recordings) Term 1 (Type of music)—single letter, A-Y Term 2 (Composer or Performer)—4 letter abbreviation Term 3 (Title of work or album)--initials Term 4 (Performer)--If a performer is prominently featured, term 4 starts with the initial letter of the performer's last name. Otherwise, term 4 is taken from the record company's label number. Example at Santa Cruz Public Libraries
Many libraries use their own systems for organizing recordings: Accession number Manufacturer’s number Adaptation of Dewey Adaptation of LC Broad subject area Color code used as location symbols Schedules with a letter notation Alphabetical by composer, author or title Music classification
Dewey Decimal Classification for Music • 780 Music • 781 General principles and musical forms • 782 Vocal music • 783 Music for single voices, the voice • 784 Instruments and instrumental ensembles • 785 Chamber music • 786 Keyboard and other instruments • 787 Stringed instruments (chordophones) • 788 Wind instruments (aerophones) Music classification
