AutoMarcDates (plugin for Koha)

This Koha plugin automatically puts creation and modification dates into the MARC record whenever the MARC record is updated. It works for both bibliographic and authority records.

Installation

IMPORTANT: This plugin relies on object_store_pre hook, which is added by Bug 28173. Make sure you have this patch. For authorities, you will also need Bug 28186

Once you've made sure you have those patches, you can install the plugin:

1. Clone the repository and add its path to pluginsdir in $KOHA_CONF
2. Flush or restart memcached
3. Run misc/devel/install_plugins.pl

Configuration

From the main plugin page (/plugins/plugins-home.pl) you can go to the plugin configuration page (Actions » Configure).

There you can enable the automatic modification of MARC records for bibliographic records, authority records, or both. You can also specify in which MARC field each date should go.

When you're done, click on the "Save configuration" button.

How it works

Whenever a Koha::Biblio::Metadata or a Koha::Authority object is stored in database, its corresponding MARC::Record is updated:

• The field chosen for modification date is set to the current date (YYYY-MM-DD)
• The field chosen for creation date is set to either biblio.datecreated or auth_header.datecreated (YYYY-MM-DD), but only if the field does not exist (the field is not overwritten)

The MARC::Record modifications happen just before the data are sent to the database, so there's no additional INSERT/UPDATE query

Known bugs / Limitations

• Control fields (001-009) are not supported
