Yes! Trove can harvest records from your DSpace using the OAI-PMH protocol!
Let us know that you are interested in contributing to Trove, and we'll set up a metadata profile that complies with Trove's requirements.
You will also need a National Union Catalogue (NUC) code from the National Library of Australia and may also need to sign a Memorandum of Understanding (MoU) in order to contribute. If you're already a LibrariesAustralia member who contribues records to LibrariesAustralia, you may re-use your existing NUC code and you won't need to sign the MoU.
We will work with Trove to set up the harvesting, we'll have you review some test harvests, and when you're happy they'll start being added to Trove.
