DESCRIPTION

The Catmandu::Plugin::Datestamps plugin automatically adds/updates datestamp fields in your records. If you add this plugin to your Catmandu::Store configuration then automatically a 'date_created' and 'date_updated' field gets added to newly ingested records.

The plugin should be set for every bag defined in your Catmandu::Store. In the examples above we've set the plugin to the default bag 'data' that is created in every Catmandu::Store.

In Catmandu::Store-s that don't have a dynamic schema (e.g. Solr, DBI) these new date fields should be predefined (e.g by changing the schema.xml or tables fields).
