Key Event Components

  • Key Event Components (KECs) are used to describe Key Events (KEs) in a computable way, by defining an action, processes, and object term that maps to controlled vocabulary and ontology terms.
  • KECs on this page can be filtered by the action, process, and object terms, as well as by source ontologies.
  • Link to source ontology terms are provided in cases where the URL was available when the ontology terms were added to the AOP-Wiki database.
  • A complete list of all KECs is available in TSV format on the Downloads Page.
