Focus of ISNI<br />
Start with largest possible pool of identities uniting<br />
legacy data<br />
Develop high quality data and matching system<br />
Development of an effective diffusion system<br />
Enable end users to place direct comment &<br />

ISNI<br />
Some Features<br />
• Confidence levels<br />
• data and match<br />
• Assignment system (online addition)<br />
• Record links to related names<br />
• Public and Private data<br />
• Direct maintenance<br />

(Green)<br />
• Assigned = 1.5 million<br />
• 3 or more VIAF sources = c.850,000<br />
• 1 or 2 VIAF sources + at least one non<br />
VIAF source = c.340,000<br />
• At least 2 non VIAF sources = c. 60,000<br />
• Work in progress – unique names<br />
• Possible matches = 300,000<br />
• Provisional = 15 million<br />
• Suspect = 12,000

Not a 1 to 1 correspondence<br />
ISNI excludes sparse, undifferentiated.<br />
Sometimes 2 ISNIs to 1 VIAF (pseudonyms). I<br />
ISNI to 2+ VIAF (merges).
ISNI includes:<br />
More musicians – composers and performers<br />

Matching – Evaluation<br />
• NACO normalisation<br />
• Common surnames<br />
• Forename equivalents<br />
• Only fullest name form used<br />
• Noise titles<br />
• Dates<br />
• flourished and lived<br />
• Suspect 1900 year only<br />
• String compression 15% faster<br />
than UNICODE string<br />
similarity<br />
