FAIR assessment of existing systems containing cytokine data

Existing system	FAIR assessment
Original cytokine dataset (Excel)	Structured, but custom-built, thus not in a uniform, globally machine readable way.
Dataset in Castor EDC	Structured in a uniform way, but no standards were applied to create a FAIR dataset.
Dataset in Opal	Structured, findable through the central LUMC warehouse and accessible through an API, but no global machine readable standards were applied to represent the data and metadata for machine processing.
