Framework and Core Cells
The i2b2 web client framework has been designed to exist and run in a structured namespace within the JavaScript VM. The base namespace is i2b2 and exists within the JSVM's global scope. Various subsystems, cells and plug-in modules also extend this namespace using an abbreviated code such as ONT for the Ontology Cell, WORK for the Workspace Cell.
