Bulk Metadata Editor is an Omeka plugin intended to expedite the process of editing metadata in Omeka collections of digital objects by providing tools for administrators to edit many Items at once based on prespecified rules.

If you use this plugin, please take a moment to submit feedback about your experience, so we can keep making Omeka better: User Survey.

The editing options available are:

• Search and replace text
• Add a new metadatum in the selected field
• Prepend text to existing metadata in the selected fields
• Append text to existing metadata in the selected fields
• Remove text from ends of existing metadata in the selected fields
• Convert to uppercase or lowercase existing metadata in the selected fields
• Explode metadata with a separator in multiple elements in the selected fields
• Deduplicate and join metadata in the selected fields
• Deduplicate and remove empty metadata in the selected fields
• Deduplicate files of selected items by hash
• Delete all existing metadata in the selected fields
• Copy/Move content from the selected field to another

Uncompress files and rename plugin folder "BulkMetadataEditor".

Then install it like any other Omeka plugin.

You may have to set the php cli path in application/config/config.ini, according to your server if it is not automatically detected:

background.php.path = "/usr/bin/php-cli"

In order to get messages about the process, you may have to set the logger:

log.errors = true
log.priority = Zend_Log::INFO

The log file is application/logs/errors.log, that must be writeable.

• After a successful process, records must be reindexed in order to find them via the quick search field.
• The change "Append text to existing metadata in the selected fields" appends text only if there is already a metadata.
• The preview may fail when there is a lot of fields or changes to prepare. The true process will still work fine even with a huge number of items and fields, because it is done in the background, without the limit set by the server. Nevertheless, it's recommended to avoid too large updates.

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.
