Program Representation
Program-Transformation.Org: The Program Transformation Wiki
Programs can be represented in various ways in ProgramTransformationTools.
Particularly important/problematic is the treatment of variables and other identifiers with restricted scope.
In addition to the internal representation used by a tool, it is important
that tools can export such a representation such that it can be manipulated
by other tools. ExchangeFormats facilite the exchange of structured representations of programs between tools.
