+- Each characteristic name in the column header SHOULD be a CV term from the EFO ontology. For example, the header _characteristics[organism]_ corresponds to the ontology term Organism. However the values could be from EFO or other ontologies. For example, for diseases we RECOMMEND to use MONDO for diseases because it has better coverage than EFO.
 
 - Multiple values (columns) for the same characteristics term are allowed in SDRF-Proteomics. However, it is RECOMMENDED not to use the same column in the same file. If you have multiple phenotypes, you can specify what it refers to or use another more specific term, e.g., "immunophenotype".
