Cohort minimal meta data model

The common minimal metadata model is intended to function supporting the analytical translational and federation use cases described in WP124 and 5 There are several nascent models in existence in this space though many of these as yet are untested in a HTP production environment of the type to be delivered by CINECA eg EDMI from EOSC and the GA4GH Clinical and Phenotypic Model Therefore we will locate merge and test the models for the use cases coming from the implementation work packages to ensure they are fit for purpose for CINECA
