The Atlantis project is the main SCADA component. It contains the implementation of the openSCADA interfaces in Java, provides interface modules to external systems like S7 PLC, OPC, SNMP, relational databases and many more. Data acquired by these interface modules can be processed, monitored and archived by the components of Atlantis.
Also contained in the project are components for building custom client and server (interface module) applications without the need to start from scratch.
Atlantis uses Aurora as a base of common functionality and Utgard and Oxygen for protocol implementations to OPC and others. Based on Atlantis the projects Orilla and Othala provide user interface components and applications that make use of the SCADA functionality that Atlantis provides.
