[Koha] Publication date fields in Koha

Hello everyone,

   I'm trying to clean up some data from the RDA-related changes when we
updated our framework a while back and have a few topics/questions regarding
the publication fields (particularly the dates):

-          Can someone explain to me where the publisher, location, and date
come from in the OPAC's search results?   The reason I ask is that Koha
seems to be pulling it from EITHER field 260 OR 264, is that correct?  I've
run a SQL query that shows I have the publisher information in only one of
those fields for every record, but Koha still displays it.

-          Should I be "worried" that for some records I have the
publication data in marcxml field 260 and for others I see it in 264, even
for recently-added records within the same framework?   Shouldn't the data
show up in the same place if using the same framework?

-          How do the biblio.copyrightdate and biblioitems.publicationyear
dates get populated?  It doesn't seem like I have anything in
'biblioitems.publicationyear' at all.should I?  And I see the
biblio.copyrightdate for those records where the 264$c marcxml field is
populated, but not the ones that have the publication information in the
260$c marcxml field.  


In case anyone else cares to look at publication date information in their
own environment, here's a SQL query that shows you all of the various
copyright date/publication year fields I mention above for ALL your biblios:

datafield[@tag="260"]/subfield[@code="c"]') AS marc260c,
ExtractValue(marcxml,'//datafield[@tag="264"]/subfield[@code="c"]') AS
marc264c FROM items LEFT JOIN biblioitems on
(items.biblioitemnumber=biblioitems.biblioitemnumber) LEFT JOIN biblio on
(biblioitems.biblionumber=biblio.biblionumber) ORDER BY items.biblionumber


Hope this makes sense.just trying to figure out where the publication data
SHOULD be and why it doesn't seem consistent in my environment.


Thanks in advance!
