News Do you share your data?

Since 2009, any Omeka website may make their data available by activating the OAI-PMH Repository plugin and may harvest OAI-PMH data sets with the OAI-PMH Harvester. Now, the OAI-PMH Harvester plugin is available with every site. Are you sharing and harvesting?

Some online repositories expose their metadata through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), an “initiative to develop and promote interoperability standards that aim to facilitate the efficient dissemination of content.”

We here at CHNM developed Omeka with interoperability as a key feature from its early stages. We also envisioned that Omeka would facilitate the sharing of digital collections and archives across institutions and individuals. For example, a regional cultural consortium could highlight collections in an Omeka site featuring digital objects from local museums, galleries, and libraries focused on on thematic topics or for the purpose of celebrating a local anniversary or special event.

Never tried this sharing thing? All you need to do is to install the OAI-PMH Repository to expose data, and tell someone–either through our list of harvestable Omeka sites, or with the OAI community. The plugin reads an Omeka collection as a set. If you have no collections, your entire archive may be exposed.

If you’re interested in testing out the OAI-PMH Harvester plugin, try these examples of harvestable sets. (Don’t worry, you may delete the harvest when you’re done testing.):

The page of harvestable sets is small and we would like to see it grow. Sign into the wiki, add your base URL, and let the Omeka community know if you are exposing your data. Thanks for sharing!
