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. This is done to allow for advanced methods of data processing, such as computer modeling, techniques of machine learning, integration into complex systems and others. For this purpose, concepts and services are developed and established, allowing the enrichment of research data in the various phases of their creation. this is done by means of a suitable, standard-compliant description with metadata. The aim 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.
Research and especially research data is extremely valuable as it is always unique. Today’s progressive digitization and instrumentation allow researchers to generate high data volume. Therefore, research data has to be inseparably linked to standardized, machine readable and complete metadata in order to achieve reproducibility and reusability, e.g. by provenance metadata. By supporting standards and tools for metadata handling, interoperability with national and international research data infrastructures can be ensured.
That’s why the Helmholtz Metadata Collaboration Platform (HMC) is needed as one of the platforms, initiated by the Helmholtz Association.
As such HMC is part of a digtal transformation process where the traditional disciplinary world will enabe the new digital world.
The goals of HMC are:
Keep research data “alive” by fostering reusability
Promote the qualitative enrichment of research data by means of metadata
Interoperability by implementing metadata standards
Increase trust and international visibility of research data (due to services for the citation and reuse of data)
Improve scientific reputation of researchers (due to high quality of research data, through their description via metadata)
Facilitate interdisciplinary research topics
To reach these goals HMC established so-called metadata hubs for each of the six research fields represented in the Helmholtz Association, which function as interface between the domain experts and HMC.
The domain experts from the different research fields bring in expertise, ideas, and demands from their own subject areas through the metadata hubs. The hubs introduce the subject metadata to the stakeholders, highlight the importance of metadata within research data management and offer advice. Along with FAIR Data Commons sustainable infrastructure services for the storage, reuse and international exchange of metadata are facilitated. Generally applicable processes, technical solutions (e.g. tools), best practices, training and consultancy services are centrally organized and embedded in international efforts. These are made available association-wide to all hubs and can be customized and utilized according to the specific subject.
Thus, the existing isolated solutions should be replaced or optimized more and more by common data objects for structuring the data comprehensibly and the possibility to identify these data sets and process them significantly.
