Data organization

OpenCGA uses a hierarchical structure to organize datasets. Briefly, Projects, Studies and Cohorts are used to organize HGVA metadata:

• Projects are entities which contain one or more Studies. 
• Study, in turn, represents a particular data set with/without samples metadata, cohorts, and obviously genomic variation data. For example, The 1000 Genomes Project is defined as a study in OpenCGA. Likewise, The Genome of the Netherlads or the Exome Aggregation Consortium are also two different studies, and so on.
• Finally, a cohort is simply a set of samples defined within a study. For example, populations and super-populations within The 1000 Genomes Project are defined as cohorts. Thus, EUR, AMR or GBR are examples of cohorts.
