CKAN Harvest is a comprehensive harvesting framework that enables automatic import of datasets from remote CKAN instances and other data sources. It provides a three-stage harvesting process (gather, fetch, import) with background job processing for scalability. The extension includes built-in harvesters for CKAN instances, CSW servers, and provides an extensible architecture for developing custom harvesters. It supports configuration options for filtering, transformation, and scheduling of harvest jobs. The framework includes a web interface for managing harvest sources, monitoring job progress, and handling errors. It requires Redis or RabbitMQ for job queuing and provides comprehensive logging and error reporting capabilities.
