The Transparent Virtual Round Table Of The Helmholtz Metadata Collaboration (HMC) Earth and Environment Hub

The mission of the Helmholtz Metadata Collaboration (HMC, is to facilitate the discovery, access, machine readability, and reuse of research data of the Helmholtz Association. Concepts and services are developed and established, allowing the enrichment of research data with standardized metadata in the various phases of their creation. The aim of HMC is to co-ordinate these services with the national and international scientific community in order to establish widely accepted practices in the handling of research data.

In the Earth and Environment Hub, we are in the process of setting up a transparent virtual round table where all communities can come together to decide which guidelines are recommended for the Helmholtz Association. Jointly agreed principles are discussed and agreed in a moderated co-design process.

Primary stakeholder profile

  • Infrastructures – leadership, technical personnel organising, standardising, and sharing their (meta)data
  • Data stewardship teams - these include personnel working for infrastructures, libraries, or thematic (meta)data management solutions/services
  • Personnel in research groups working to standardise and curate (meta)data

In this presentation we will introduce to the current HMC activities and outcome: Our process for developing a guideline is planned as a coordinated procedure. For every single implementation guide, we go through the same questions, up to tests - based on use cases and definition of abstract test classes, in order to be able to validate the implementation. Our planned results are recommendations and detailed implementation instructions that enable interoperability - not only in the Helmholtz Association, but also in national and international communities.
