\title{Class "redlModel" represents librdf model in Redland RDF library }
\description{represents librdf model in Redland RDF library	}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("redlModel", ...)}.
They encapsulate the reference to the librdf model object in Redland RDF library.
}
\section{Slots}{
	 \describe{
    \item{\code{ref}:}{Object of class \code{"externalptr"} pointer to
malloc'd model space. }
    \item{\code{storagetype}:}{Object of class \code{"character"} can
be "bdb" or "internal" }
    \item{\code{stateEnv}:}{Object of class \code{"environment"} used
to indicate whether model is open or not }
    \item{\code{world}:}{Object of class \code{"redlWorld"}, the world
object in which the model or URI was constructed  }
    \item{\code{URIstring}:}{(for redlURI: string in use as URI }
  }
}
\section{Methods}{
  \describe{
    \item{coerce}{\code{signature(from = "redlModel", to = "data.frame")}: 
 simple transformation to 3-column dataframe (subject, predicate, object) }
    \item{coerce}{\code{signature(from = "redlModel", to = "graphNEL")}: ... }
    \item{freeRedl}{\code{signature(x = "redlModel")}: call
the librdf close method; kills the model. }
    \item{getStatus}{\code{signature(x = "redlModel")}: determine if
a model object is open from the perspective of R }
    \item{ref}{\code{signature(x = "redlModel")}: extract the
externalptr }
    \item{setStatus}{\code{signature(x = "redlModel")}: set a
status flag in the R container for the model object}
    \item{show}{\code{signature(object = "redlModel")}: simple report  }
    \item{size}{\code{signature(x = "redlModel")}: tell the number
of statements in the model }
