The ontology is best viewed using DAG-Edit The Definitions for each term can be found listed in alphabetical order below the ontology. In addition, the FAO ontology and definitions files may be retrieved from the Open Biological Ontology site.
Each line in the ontology contains the term name, a symbol denoting the relationship of that term to its parent, '%' meaning an example or instance of the parent or '<' meaning literally a part of the parent, the unique identifier for the term (FAO:nnnnnnn), any synonyms, and any additional parents of the term.
%ascocarp ; FAO:0000008
< ascocarp-bound ascus ; FAO:0000004 % ascus ; FAO:0000014
In the lines above, 'ascocarp-bound ascus' is a term and it is a
part of an ascocarp (represented with '<'). The unique
identifier for the term is FAO:0000004. FAO:0000004 has an additional
parent: 'ascus ; FAO:0000014'. If you
look down the ontology further you will see 'ascocarp-bound ascus ;
FAO:0000004' is also listed under FAO:0000014 and is an example of
('%') an ascus ; FAO:0000014.
