Class: Entity

comment "Definition: A discrete biological unit used when describing pathways. Rationale: Entity is the most abstract class for representing components of a pathway. It includes both occurents (interactions and pathways) and continuants (physical entities and genes). Loosely speaking, BioPAX Entity is an atomic scientific statement with an associated source, evidence and references. Usage: There is no recommended use-cases for instantiating this class. Please, use its subclasses instead. Synonyms: element, thing,biological unit, statement, observable." (string)
