\title{Annotation of DO Identifiers to their Parents} 
\description{
  This data set describes associations between DO
  terms and their direct parent  terms, based on the directed acyclic
  graph (DAG) defined by the Disease Ontology Consortium. The format is an R
  object mapping the DO  terms to all direct parent terms, where a
  direct parent term is a more general DO term that immediately precedes
  the given DO term in the DAG.
}
\details{
  Each DO  term is mapped to a named vector of DO  terms. The name
  associated with the parent term will be either \emph{isa}, \emph{partof},
  where \emph{isa} indicates that the child term is a more specific version
  of the parent, and  \emph{partof} indicate that the
  child term is a part of the parent. 

 
  Mappings were based on data provided by: Disease Ontology
  With a date stamp from the source of: 20100823 (sub_version 1689)
