Kuha2: A New Open Source DDI Aware Metadata Server

Kuha2 is a metadata server that provides descriptive social science research metadata for harvesting via multiple protocols and a variety of metadata standards. Kuha is still evolving but it has been in production use at FSD from April 2018, serving metadata e.g. for the CESSDA Data Catalogue. The system is open source and released under EUPL license.

Kuha supports OAI-PMH and OSMH for harvesting. Metadata output is provided in DDI-C 2.5 and unqualified DC for OAI-PMH and in JSON for OSMH. Input is through a RESTful API in JSON or by utilizing built-in mappings for DDI 1.2.2 and 2.5 XML. Kuha’s internal metadata model comprises CESSDA Metadata Model v1 mandatory elements.

Kuha2 could provide archives with an easy-to-use entry point for integrating into CESSDA Data Catalogue. This presentation will discuss Kuha2’s features, its usability for prospective user and our future plans with it.
