This extension provides a harvester for multiple metadata formats in one single harvester, for the use of CKAN. Universal metadata harvester for CKAN, uses DDI and OAI-PMH harvesters to streamline the harvesting to one harvester. Provides a unified approach to harvesting different metadata standards. Very early CKAN extension from 14 years ago. Uses JSONPickle for data serialization. Pure Python implementation. Likely incompatible with modern CKAN versions.
