Novotny %J Comparative and Functional Genomics %D 2004 %I Hindawi Publishing Corporation %R 10.1002/cfg.429 %X An explicit formal-ontological representation of entities existing at multiple levels of granularity is an urgent requirement for biomedical information processing. We discuss some fundamental principles which can form a basis for such a representation. We also comment on some of the implicit treatments of granularity in currently available ontologies and terminologies (GO, FMA, SNOMED CT). %U http://www.hindawi.com/journals/cfg/2004/349318/abs/
