=head1 NAME |
use LONCAPA::Configuration; |
|
|
B<searchcat.pl> - put authoritative filesystem data into sql database. |
|
|
|
=head1 SYNOPSIS |
|
|
|
Ordinarily this script is to be called from a loncapa cron job |
|
(CVS source location: F<loncapa/loncom/cron/loncapa>; typical |
|
filesystem installation location: F</etc/cron.d/loncapa>). |
|
|
|
Here is the cron job entry. |
|
|
|
C<# Repopulate and refresh the metadata database used for the search catalog.> |
|
C<10 1 * * 7 www /home/httpd/perl/searchcat.pl> |
|
|
|
This script only allows itself to be run as the user C<www>. |
|
|
|
=head1 DESCRIPTION |
|
|
|
This script goes through a loncapa resource directory and gathers metadata. |
|
The metadata is entered into a SQL database. |
|
|
|
This script also does general database maintenance such as reformatting |
|
the C<loncapa:metadata> table if it is deprecated. |
|
|
|
This script evaluates dynamic metadata from the authors' |
|
F<nohist_resevaldata.db> database file in order to store it in MySQL. |
|
|
|
This script is playing an increasingly important role for a loncapa |
|
library server. The proper operation of this script is critical for a smooth |
|
and correct user experience. |
