New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.
OAI-PMH Harvester is a module for Omeka S that allows to import records from OAI-PMH data providers.
Some online repositories expose their metadata through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). This module makes it possible to harvest that metadata, mapping it to the Omeka data model. The module can be used for one-time data transfers, or to keep up-to-date with changes to an online repository (not yet implemented).
Currently the module is able to import Dublin Core, and METS if the profile uses Dublin Core.
- Dublin Core is an internationally recognized standard for describing any resource. Every OAI-PMH data provider should implement this standard.
- METS is the Metadata Encoding and Transmission Standard and is mainly designed for digitalized items, as books, journals, manuscripts, video and audio.

See general end user documentation for Installing a module and follow the config instructions.
- Go to the Oai-Pmh Harvester page.
- Type or paste the address of the repository you want to fetch data from (usually something like http://sample-host.org/data/oai)
- Cilck the View Sets button.
- Choose the sets you want to harvest by checking the box Harvest this set ? for each set you want to be harvested.
- Choose the protocol you want to use : oai_dc or oai_dcterms or mets for each set.
- Click the Harvest button.
- A task should be created. The module creates a collection for each fetched set and then proceeds to harvest the content.
- Add a search field in the advanced search.
- Check harvest of a repository without sets.
- Original plugins shows details with duplicates of harvested entities.
- Allow to update and check deletion.
- Integrate more formats (CDWA Lite, Ead, etc.).

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

This module has first been built by Numerizen as a simplified version of the plugin for Omeka Classic, shamelessly copied whenever possible: the work consisted mainly in adapting the code to Omeka-S - i.e Laminas (formerly Zend Framework 3). It was improved for the Bibliothèque nationale universiaire de Strasbourg for the digital library Numistral.
