Links from Current Non-VIAF sources to VIAF clusters

VIAF source links to ISNI = > 7.3 million

viaf and isni are complementary
VIAF and ISNI are Complementary

ISNI Scope

  • Persons
    • + musicians, researchers
  • Organisations
  • (excluding sparse)
  • (excluding undifferentiated)
  • Includes private data

VIAF Scope

  • Persons
  • Organisations
  • Works / uniform titles
  • Expressions
  • Meetings
  • Geographic
  • All public data
viaf and isni are complementary1
VIAF and ISNI are Complementary

ISNI Role

  • Create permanent IDs
    • By batch
    • On demand
  • Diffuse those IDs
    • Libraries, trade, rights management, professional societies, education

VIAF Role

  • Ingest authority records from the world’s major national and research libraries
  • Make clusters
  • Expose and diffuse
viaf and isni are complementary2
VIAF and ISNI are Complementary

ISNI System

  • Batch load
  • Online request API
  • Web site (English only)
    • Allows end user input
    • Member input and correction
    • 16+ indexes
  • SRU; soon linked data
  • Quality Team monitoring & correcting
  • Diffusion, including corrections

VIAF System

  • Harvester
  • Clustering mechanism
  • Web site (5 interface languages)
  • Download in multiple formats
  • Linked data & SRU
  • 1 million personal visitors p.a.
isni quality team
ISNI Quality Team
  • Samples data regularly
    • c. 2% VIAF clusters have mixed identities
    • Duplicate clusters are higher, nearer 5%
  • Makes corrections at cluster level
    • Merges, splits, error notifications
    • Access to cataloguing client / macros
  • Makes system recommendations
  • Gives approval for single source assignment
  • Responds to End User input
slide10

Example record fixed by QT

  • 3 VIAF records merged
  • ISNI sources British Library Sound Archive, MusicBrainz
  • notice instruments, performances
duplicate clusters
Duplicate clusters
  • Cause duplicate ISNI assignment
    • Where both clusters have more than 3 VIAF sources
    • Where an ISNI source matches with a single or 2 source VIAF record
    • (Where VIAF sources move between the clusters)
  • ISNI as a VIAF source will help VIAF merge clusters where ISNI QT has manually merged them (2,444)
  • ISNI has flagged 481,766 VIAF records as possible duplicates

Titles of other identities

Vocabulaire anglais-français, français-anglais, de terminologie économique et juridique

La notte comincia ancora una volta

undifferentiated identities
Undifferentiated Identities
  • Signalled by ISNI Quality Team
    • Most cases encountered now are due to source data
  • ISNI QT would like to notify VIAF sources directly
  • VIAF is currently notified by a field in the ISNI record; notifications indicate if a cluster error or a source error
public identities versus persons
Public Identities versus Persons
  • ISNI is assigned to public identities. Pseudonyms = different identities; but related
  • VIAF sources- some treat as name variants, some as related names
  • ISNI suite of programs
    • Converts pseudonym name variants to related names
    • Flags records with dissimilar main names
    • Links and protects
viaf isni task force
VIAF ISNI Task Force
  • Policy on pseudonyms
  • Study notification work flows
    • How to remove record protect flags
  • Participate in cluster sampling in VIAF and ISNI
  • Help define new anomaly detectors
    • ISNI has dissimilar main name / publishing before age 9, life span greater than 120 years

viaf sources
VIAF sources
  • Flag undifferentiated records
    • e.g. those generated by programs comparing authority and bibliographic name strings
  • Respond to ISNI notifications
    • correct “home” data
  • As ISNI Members:
  • Control “own identities” in VIAF and ISNI
    • * Check possible matches and suspect records on ISNI
  • Use ISNI for direct maintenance of clusters
    • * Will generate notifications to VIAF and VIAF sources
