\section{Introduction}
Low-level interfaces for the Model Definition Repository (MDR) and the
Schema Transformation Repository (STR) have been developed to allow
access and update of data in the MDR and STR.  Details of the MDR and
the STR are documented in~\cite{boy01a}.  The AutoMed Repositories API
is provided as a higher-level interface for the MDR interface and the
STR interface.  The intefaces to the MDR and STR utilise the Data Source
Repository (DSR) interface.  The DSR interface can be, in a sense, viewed
as a helper class for the MDR and the STR interfaces, in particular, it
provides methods for connection to databases and common functions used for
development and testing of the MDR and STR interfaces (e.g., display content
of the repositories).  The DSR interface is also expected to facilitate the
important task of connecting the AutoMed front end tool to the MDR and STR.

In this report, we briefly describe the usage of the DSR interface in
Section~\ref{sec:DSR}.  Some of our early ideas about the design of the
AutoMed Repositories API and how it will be used are reported in
Section~\ref{sec:repAPI}.
