ORCHESTRA Terminology

**Semantic type:** Intellectual Product

**Definition:** ORCHESTRA is a multinational project funded by the European Commission to advance the knowledge of the SARS-CoV-2 infection and its long-term effects. Partners from the Berlin Institute of Health at Charité have been tasked with the harmonization and standardization of data in the project. International interoperability standards have been introduced to define the study data elements (variables) of the prospective and retrospective ORCHESTRA clinical studies. This enables semantically interoperable processing of diverse data that is being collected across countries and cohorts. While study variables range across several informational domains, NCIt terms in particular are used to represent omics variables and viral sequencing details.
