Abstract: Abstract The overall goal of the top-level layer of IDL, a Lisp-based statistical programming environment, is to package together implementation level components into higher-level computational abstractions that better reflect the domain of interest. This is accomplished through extensive use of object-oriented programming. Measurement and tag objects capture context. Distribution and transformation objects reflect useful data-independent abstractions. Situation objects express an intent to pursue a particular line of investigation. Analyses themselves are captured as summaries or model objects. Audit trails are implemented by chaining summaries to their situations.
