\section{Introduction}
-As the size, complexity and cost of modern physics detectors increases, the need for detailed simulations of the experimental setup plays an increasingly important role. Designing detector systems composed of many disparate subsystems requires efficient tools to simulate the detector response. Comparisons of different technology options, or geometric layouts, are facilitated if the results can be obtained with a flexible, easy-to-use simulation framework.

\subsection{GDML}
-The Geometry Description Markup Language (GDML) is a language for describing detector geometries using materials, mathematical variables and definitions, solids such as boxes and tubes, and a hierarchical structure of logical and physical volumes. Originally developed as a stand-alone application, GDML has become part of the Geant4 source distribution. Therefore, it serves as an ideal starting point for a complete detector description language. The syntax and usage of GDML is fully described in the \textit{GDML User's Guide}~\cite{gdmlguide} but a brief overview is provided here for completeness. Every valid GDML file has the following basic structure.

-The first five fields of the above identifier derive from the {\tt physvolid} values. The ``x'' and ``y'' values are read from the segmentation bins at the hit position. The concatenation of these values identifies a unique readout channel in the detector. The packed values can be subsequently decoded within an external framework to retrieve the associated detector information for a specific hit.

The packed values can be subsequently decoded within an external framework to retrieve the associated detector information for a specific hit. Accessing the field information from such a common source for both simulation and reconstruction ensures a commensurate encoding and subsequent decoding of the bit packing.
