Does jOAI support selective or incremental harvesting?

Yes. After performing an initial full harvest of the repository, harvesters may use datestamps to request only those records that have changed or been deleted since that last time of harvest, which can greatly reduce the number of records transferred over the network over time. The data provider implements deleted records and datestamps in accordance with the OAI-PMH to support selective and incremental harvests.
