PNI Code list query

[mdovey]

The PNI Code list is as follows:

Code ID	Code value	Definition	Notes
PNI01	01	Proprietary	ONIX code ‘01’
PNI02	16	ISNI	ONIX code ‘16’
PNI03	18	LCCN	ONIX code ‘17’
PNI04	21	ORCID	ONIX code ‘21’
PNI05	31	VIAF ID	ONIX code ‘31’

Why doe PNI03 have a different value to the ONIX code it corresponds to? Is this a typo, or deliberate?

This does feel like an error, as the other codes align with the ONIX list values and 18 is an LoC Authority name.

Good catch! This error exists in code list PNI from when it was introduced in LCF v1.0.1. Here is what ONIX code list 44 currently contains:

Value	Description	Notes
...	...	...
17	PND	Personennamendatei – person name authority file used by Deutsche Nationalbibliothek and in other German-speaking countries...
18	NACO	A control number assigned to a Library of Congress Control Number (LCCN) Name Authority / NACO record
...	...	...

Since the error is only in the Notes column, we can correct the Note and mark it as corrected in v1.3.0.

But that does leave open the question as to whether the Definition 'LCCN' is correct or not. We could leave it as it is, change it to 'NACO' or change it to 'LCCN / NACO'.

I've checked back-issues of the ONIX code lists. Code '18' was described as 'LCCN' until Issue 51 (October 2020), when it changed from 'LCCN' to 'NACO'. I propose that we change the Definition of code PNI03 from 'LCCN' to 'NACO', and add a note on this change to the Notes field:

Code ID	Code value	Definition	Notes
PNI01	01	Proprietary	ONIX code ‘01’
PNI02	16	ISNI	ONIX code ‘16’
PNI03	18	NACO	ONIX code ‘18' (Definition was 'LCCN') Definition updated and Note revised in Issue 5
PNI04	21	ORCID	ONIX code ‘21’
PNI05	31	VIAF ID	ONIX code ‘31’
