Plugin for Omeka Classic. Allows to define rules in order to check while adding an item if it already exists in Omeka database.

A rule is a combination of an Item Type and one or more Elements. A rule applies to an Item only if its Item Type matches.

A duplicate is an Item which have the same values in the Elements defined in a rule as the Item is being added. When a duplicate is found, the Item is not saved and an error message is shown.

Use it at your own risk.

It's always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
