\usage{
data(GDI_NCIThesaurus)
parents(term, nom)
children(term, nom)
getDefs(term, nom)
}
\arguments{
  \item{term}{ character string, term }
  \item{nom}{ instance of class \code{\link{taggedHierNomenclature}} }
}
\details{
DAG-structured nomenclatures are in wide use.
For any term, one can seek parents (generalizations)
or children (specializations).
These resources prototype tools for dealing with
such structures, including provenance information.
