The Helmholtz Metadata Collaboration (HMC) Hub Earth and Environment seeks to create a framework for semantic interoperability across the diverse research data platforms within the Helmholtz research area Earth and Environment (E&E). Standardizing metadata annotations and aligning the use of semantic resources are essential for overcoming barriers in data sharing, discovery, and reuse. To foster a unified, community-driven approach, HMC, together with the DataHub, has established the formal "Metadata-Semantics" Working Group, which brings together engaged data stewards from major Helmholtz research data platforms within the E&E domain.
As part of its strategy to standardize metadata annotation in collaboration with the community, the working group will begin by harmonizing device-type denotations across two Helmholtz sensor registries: the O2A REGISTRY, developed at AWI, and the Sensor Management System (SMS), maintained by UFZ, GFZ, KIT, and FZJ. This harmonization involves the development of a shared FAIR controlled vocabulary and the implementation of a peer-reviewed curation process for it.
The common vocabulary will support the creation of referenceable ad-hoc terms when needed, incorporate versioning and quality assurance measures, and establish links with existing terminologies in the field (e.g., NERC L05, L06, ODM2, GCMD). Its development will involve experts from various disciplines within Helmholtz E&E and contributors from other data infrastructures to ensure its applicability to additional research data entities in Helmholtz E&E (e.g., PANGAEA or GFZ data services).
Furthermore, a strategy and governance framework will be developed, allowing for hosting and maintaining the vocabulary using terminology services provided by the Base4NFDI consortium. By integrating knowledge, tools, and infrastructure, this initiative brings together the expertise distributed across Helmholtz centers. The proposed approach for creating, maintaining, and hosting terms for measurement device types is intended to serve as a model for the development of other collaboratively used controlled vocabularies in the research domain. Ultimately, this effort will provide general recommendations for building semantic interlinkages across research data infrastructures.
