+ Workflow Management Systems are systems designed to facilitate and manage
+ tasks within an organisation. These tasks are topologically organised, in
+ terms the its direct requirements. The system then executes the workflow
+ such that all task dependencies are met.
+ \section{Zamani Project and Cultural Heritage}
+ The \emph{Zamani Project}\footnote{Zamani Project:http://www.zamani-project.org/}
+ was started out of the Geomatics Department at the University of Cape Town.
+ This project aims to accurately record the physical and architectural nature
+ and dimensions of African Heritage sites.
+
+ Heritage sites are mapped using highly sophisticated technology which are
+ used to create a variety of digital objects which include:
+ \begin{inparaenum}[i)] \item Geographic Information Systems; \item 3D
+ Computer Models; \item Panoramic Photographs\end{inparaenum} and others.
+ The team has recorded sites in Ghana, Mali, Kenya, Ethiopia, Tanzania and
+ South Africa. Which other sites currently in progress or being planned.
+
+ These are some of the best, and most accurate heritage documentation
+ in the world.
+ These produces a very large collection of data items that has to be managed
+ within the project. Currently the team is experiencing a problem managing
+ the vast amount of data items that needs to be processed. The size of these
+ data items provides a challenge to traditional workflow systems that are
+ currently available.
+ \section{System Outline}
+ This project to created a Workflow system that could effectively
+ automate the management of the heritage preservation processes.
+ This would manage the process starting from the raw scans and photographs
+ through the creation of all the digital artifacts. Figure~\ref{intro:basic}
+ shows the simplified working of the system.

+ \label{intro:basic}
+ \end{figure}
+
+ \noindent The system starts with with
+ core set of input file. The workflow is then executed which initiates a set
+ of topological tasks. The processes then generates output data items.
+
+ The tasks that are required in order to produce these data items
+ could either be tasks executed by a users or it can be
+ automatically completed by the server. The system aims to automate these
+ tasks to the maximum extent possible.
