The C2M2 project entity is a generic container for groups of files, biosamples and/or subjects that are part of the same research endeavor.
At least one project must be defined as the root (top-level project) for each submitting Common Fund Program, representing the Program itself. The project.tsv table will have one row for each project you define. Subprojects can be assigned using the project_in_project.tsv table.
