• All public data

ISNI Scope• Persons

– + musicians, researchers• Organisations

• (excluding sparse)• (excluding

undifferentiated)

• Includes private data

VIAF and ISNI are Complementary

VIAF Role• Ingest authority records

from the world’s major national and research libraries

• Make clusters• Expose and diffuse

ISNI Role• Create permanent IDs

– By batch– On demand

• Diffuse those IDs– Libraries, trade, rights

management, professional societies, educational institutions

Synchronisation ISNI to VIAF

• VIAF provides full file each month• ISNI compares previous & current files &

creates separate files for processing– Deletes (VIAF cluster ID in old but not new)

• If assigned or has other sources, source becomes ISNI

– Contents changed– Sources added or deleted– New (VIAF cluster ID in new but not old)– Re-matches VIAF deletes

• VIAF cluster movement reports for BL and BnF

Thank you for using the ISNI database and suggesting improvements to your record. There is now another ISNI record for Marco Antonio dos Santos Casa Nova (ISNI 0000 0004 3077 6045). I have corrected your record, removed the erroneous titles and added a link to your online CV (Lattes database).

If you have any further queries, please let me know.

• Email to SourceI am part of the the ISNI Quality Team (experts from the British Library and

Bibliothèque nationale de France in charge of the quality of the ISNI database). We perform manual checking and corrections in the ISNI database such as splits, merges/deduplications and data corrections. ISNI Quality team received a request from an enduser about ISNI records 0000 0001 1748 8848 and 0000 0004 3077 6045, VIAF 19998588 and their related

Authority record XXX 109895029 mixes 2 identities (see the snapshot below) :

1/ Marco Antonio Casanova (ISNI 0000 0001 1748 8848) 2/ Nova, Marco Antonio dos Santos Casa (ISNI 0000 0004 3077

6045) Philosoph, and author of "Segunda consideração intempestiva da

utilidade e desvantagem da história para a vida" I hope this information will be useful.

Correction – Cluster Error

• ISNI marks its two records as verified & sends to VIAF• These records are given the same status as XA

records in VIAF clustering. • No two XA records may occur in the same cluster

End User Note

• It seems 2 ISNIs has been assigned to the French singer Laika Fatien (born 1968 in Paris): ISNI 0000 0000 8065 8419 and ISNI 0000 0000 7238 637X. I think the last one can be deleted.

Correction – Merged duplicate• Reply to End User

• Thank you for using the ISNI database and providing us with information about the duplicate records for Laika Fatien.

• • There is now just one record on the ISNI database for this identity –

ISNI: 0000 0000 8065 8419.• • If you have any further queries, please let me know.

• Notification to VIAF via ISNI record

• ISNI record contains verification note (i.e. treat as XA)

• ISNI record contains 2 VIAF cluster identifiers

• 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

ISNI Assignment Agency

• Matching, merging and splitting infrastructure• Correction of errors• Sampling and anomaly checks,

• e.g. date anomalies, unlikely mixture of sources

• Pseudonym splitting• Re-importing and re-matching• Diagnostic indexes and reports• Enrichment

– e.g. Wikipedia, Dewey

• Notification system

VIAF ISNI Interoperability Task Force

• Met in Paris 22-23 April 2014• Representatives from

– Bibliothèque nationale de France– Biblioteca Nacional de España– British Library– Deutsche Nationalbibliothek– Sudoc– OCLC (VIAF system)– OCLC Leiden (ISNI Assignment Agency)

Recommendations to VIAF at OCLC

• Use profession and other disambiguating data• Investigate making an anomaly report• Investigate changing the clustering rules to flag and prevent a record with a mixed

identity from entering the clusters where 2 or more sources have established separate identity

• Investigate changing the clustering rules to prevent duplicate clusters.• Provide deprecated VIAF Ids in the distributed data• Treat records from ISNI that are flagged as manual as XA records• Include ISNI in RDF• Remove test from ISNI icon• Only show one name form for ISNI in the wheel• Investigate why SUDOC titles are not appearing

Recommendations to ISNI at OCLC

• Flag manual merges and splits (joint specification to be made)• Indicate to VIAF that a VIAF source needs to be split from a VIAF cluster

(joint specification to be made) • Keep up to date with VIAF• Produce anomaly reports• Produce notifications to VIAF sources• [Provide only one ISNI record per VIAF cluster ID; make split off records

ISNI source]• [Provide records with ISNI source to VIAF]

• Mark undifferentiated authorities or consider not supplying them to VIAF• Include nationality, particularly for own national identities• Use VIAF in authority control and select VIAF cluster ID

– Also use ISNI• If a mixed identity is found in VIAF or ISNI, use either the public interface

or [preferably] the member interface of ISNI to request resolution by the ISNI Quality Team. All manual corrections made in ISNI will come to VIAF as records with XA status to ensure merges or splits.
