[Koha] Importing Authority data

[Bohdan Šmilauer]

Hello Mr. Rivikantha,

I followed similar way in Koha 3.14 as you did. If you have for disposal 
separate Authorities files for authors, corporations, geographic, topics, 
chronological, meetings, genre/forms, ... import them as first in compressed
format ISO 2709 (.mrc). Convert it to UTF-8 coding. For this you can use 
MarcEdit Program http://marcedit.reeset.net/tutorials. This authorities 
files can have additional useful information (e.g. Narrower term, Broader 
term, Relative term, UsedFor term, Use term, Biographic data for authors, 
etc. abide to MARC21 Authority standard, see http://www.loc.gov/marc/
authority/). Authorities during the import are newly numbered in the field 
001 beginning with 1, followed by 2, 3, 4 ....etc. After this import, you 
will be able to search them in OPAC Authority search. They are stored in the
MySQL table auth_header and contemporary  they are indexed by Zebra. You 
must wait appx.. 10 min. until the cron job planned in /var/spool/cron/
crontabs/root  (*/10 * * * *  __KOHA_USER__  $KOHA_CRON_PATH/../migration_
tools/rebuild_zebra.pl -b -a -z >/dev/null) rebuilds Zebra indexes. You can 
display your crontabs by command

/var/spool/cron/crontabs# crontab -u root -l  . Check this step by searching
in imported Authorities.

Then import Bibliographic records in the format ISO2709 to Koha, with system
preference AutoCreateAuthorities = NoAllow and BiblioAddsAuthorities = 
NoAllow. No new authorities will then be added.

Then set preference UseAuthoritiesForTracings =  Don't use authority record 
numbers instead of text strings for searches from subject tracings.

Then run the script link_bibs_to_authorities.pl in this manner:

# export PERL5LIB=$PERL5LIB:/usr/share/koha/lib

# export KOHA_CONF=/etc/koha/sites/name_of_koha_instance/koha-conf.xml

# /usr/share/koha/bin/link_bibs_to_authorities.pl

This should  compare text in Biblio (fields 100$a, 110$a, 650$a,..etc) with 
Authority texts. If it matches, the number of Authority will be added to $9 
subfield in biblio fields100, 110, 111, ...650,....etc) and these are the 
desired links. If some Authorities are missing in authority database after 
that, you can create them setting the preferences:

AutoCreateAuthorities = Allow and BiblioAddsAuthorities = Allow and run 
again

# /usr/share/koha/bin/link_bibs_to_authorities.pl

The missing authorities will be created in simplest form, but each 
bibliorecord will crate its own authority, so that many of them will be the 
same and will be multiplied for several times, e.g. topics. Don't be 
unhappy, you can  unify them by setting preference linkermodule=LastMatch 
and by repeating the script. for several times:  # /usr/share/koha/bin/link_
bibs_to_authorities.pl . The last occurrence  of authority will be used many
times, the earlier occurrence 0 times (unused). Then run the script # /usr/
share/koha/bin/migration_tools/remove_unused_authorities.pl aut=TOPIC (PERSO
_NAME, MEETI_NAME,  see table auth_types in MySQL)

The unused authorities should disappear. That is all, how simple!

Předmět: [Koha] Importing Authority data

"Dear all,
My name is Rivikantha and I work as a computer programmer inUniversity of 
Peradeniya main library. We are in the process of implementing  Koha as our 
integrated library managementsystem.  Currently we have imported datafrom 
the current library management system to Koha via a marc file and all 
thebibliographic data seems to be in order. I can search a book and all the 
dataseems to have imported successfully. 

But authority data such as Author Name has not beenimported. I cannot search
authorities which results in 0 results.
·        Does I have to import authority data separately orhas the marc 
import process has a failure. ·        If so what is the procedure to import
authoritydata from the current system.·        Is there a way to generate 
authority data frombibliographic data.
I am currently facing this problem and our data migrationprocess has come to
a complete stop. We have to make the system live by april.So any help would 
be greatly appreciated. 

Thank you
Rivikantha
Computer Programmer.
