  The intent of this report is to do a background study of the two given OSS
case study systems namely GIPSY and DMARF. It is a wide research area in which
different studies are being carried out to get the most out of it. It begins
with a formal introduction of the two systems and advance with the complex
architecture of both. GIPSY (General Intensional Programming System) is a
multi-intensional programming system that delivers as a framework for compiling
and executing programs written in Lucid Programming Languages. DMARF
(Distributed Modular Audio Recognition Framework) is a Java based research
platform that acts as a library in applications. As these systems are in their
evolving phase and a lot of research is being done upon these topics, it gives
us motivation to be a part of this research to get a deeper look into the
architectures of both the systems. For the evaluation of quality of metrics of
the two open source systems, we have used a tool namely Logiscope. It is a tool
to automate the code reviews by providing information based on software metrics
and graphs.
