--- Comment #3 from Paul Poulain <paul.poulain at biblibre.com> ---
One of our libraries is interested by this feature, they asked me to have a
look at this ticket.

Some explanations (from history) : I'm the developer who wrote the MARC
management in Koha (in 2003...)
The $9 was chosen to store a link between biblio & authority because it was for
local use (as any field/subfield with a 9).
In UNIMARC, the $3 was a possible field (as it contains the linkage), in MARC21
there was no subfield for that. But anyway, I thought (and still think) it was
better to keep the $3 as it is and use a local field because it stores a local
information (the authid of the authority in the local [Koha] system) In France,
the SUDOC (national academic catalogue) makes an extensive usage of the $3, we
must preserve it.

Otherwise :

That's a very good idea to add the wikidata reference (or any other one) and
your specification seems OK, I have a couple of comment though:

- switch the feature on/off
=> not sure it's needed, if the next syspref is empty, it's OFF ;)

- source of the standard IDs (possibly different for different biblio fields?)
(standard in MARC 21 authority: 024, but may be also 010/035) (a list)
=> I agree, it must not be at a global level. But counter-proposal : define
that in the authority level. In the authority definition, we define which
authority field must be copied in the biblio field [for example, corporate name
is copied from the 110 of the authority]. Shouldn't we have another option to
say "024$a" is copied in the $1 of the biblio ? [the $1 is possible for
UNIMARC, it's an unused field]

- how many ids should be copied (= how may $0 added): only the first found or
all of them
=> I would say "copy only one". Of maybe add another option in the authority
definition to say "add the 1st where source/$2=[_____]" [$2 is valid for
UNIMARC too]

- if an extra link/icon should be generated in display (OPAC / librarian)
=> I think we just need to improve the XSLT for that.

Very interesting proposal though ! I'll continue talking with the library to
see if they can sponsor the dev
