Technical Specs

Genomic Data Infrastructure (GDI) is a federated multi-layer technical infrastructure that enables collection of metadata about various genomic datasets from different countries (nodes), and additionally enables requesting access to the datasets (for reasearch purposes).

The key players in the ecosystem are the following:

  1. The central User Portal of the GDI
    • collects information about available genomic datasets from the FAIR Data Point catalogues of different nodes;
    • uses a Beacon Network for requesting allele frequencies and matching sample count of genomic variants from different nodes;
    • enables authenticated researchers to select datasets and request access to them.
  2. GDI National Nodes
    • provides a self-service portal for data-providers;
    • provides data-services (FAIR Data Point, Beacon) to the User Portal;
    • helps to locally conduct evaluations of data-access requests;
    • helps to set up secure processing / trusted research environments.
  3. GDI Data Providers
    • a legal entity (organisation) that has some locally hosted genomic data to share for research;
    • defines its datasets to be published on the GDI;
    • manages the visibility of its datasets;
    • participates in the data-access evaluation process;
    • prepares minimised data files for the approved researcher;
    • uploads the research data to a dedicated secure research environment;
    • possibly reviews research outputs before releasing them to the researcher.
