## Project Information

# NFDI4Health

National Research Data Infrastructure for Personal Health Data (NFDI4Health) is a german national project that deals with data generated in clinical trials, epidemiological and public health studies. It aims to foster the fulfillment of the FAIR principles requirements and collaboration between these communities. The mission of NFDI4Health is to provide new opportunities for the scientific use of personal health data while respecting privacy requirements.
Based on the FAIR principles, services are provided to researchers to permanently store, semantically enrich and share data in interoperable form and to merge data from different sources.

## Description of the NFDI4Health Metadata Schema (NFDI4Health-MDS)

NFDI4Health developed a metadata schema (MDS) based on several international standards and studies' registries to collect metadata from clinical, epidemiological and Public Health studies, and associated resources.

The MDS is composed of a generic, core module and further specialized modules to describe the design of certain resources or for specific use cases.

At this stage we provide the following versions of the MDS in ART-DECOR:

- Version 3.0 (Published)

- Version 3.3 (Published)

  - Publisso

  - Simplifier

  - Graphical Representation

  - Data harmonisation and publication - NFDI4Health

- Version 3.3.1 (In Progress)

## Aim of the NFDI4Health-MDS

The NFDI4Health metadata schema (NFDI4Health-MDS) is an information model tailored to describe design elements and context of clinical, epidemiological, and public health studies as well as associated resources such as documents (e.g., study protocol, instruments) or datasets. The NFDI4Health-MDS improves the FAIRness of the cataloged studies and associated resources by making the content searchable and accessible through dedicated centralized search portals such as the German Central Health Study Hub (https://csh.nfdi4health.de/), as well as locally through systems such as NFDI4Health Local Data Hubs (https://www.nfdi4health.de/en/service/local-data-hub.html).

To ensure a broad applicability, the NFDI4Health-MDS combines common elements from reference data models and their controlled vocabularies (value sets). It is modular in design to allow the description of studies from different domains with their specific metadata requirements. In addition to a common core module, the NFDI4Health-MDS contains modules that are specific to certain scientific domains, such as nutritional epidemiology, or for the description of chronic diseases. These modules were developed based on input from subject matter experts involved in NFDI4Health use cases. The metadata model is constantly expanded based on the needs of the user community.

This work serves as base for the NFDI4Health-MDS Simplifier Project.
