FactsExtraction is the first step of a ReverseEngineering or ReEngineering effort. An extractor (a.k.a. parser or analyzer) processes the LegacySystem's artifacts to extract useful information (a.k.a. facts).

There are many different approaches (please update/expand):

• lexical analysis
• parsing
• hybrid
  • IslandGrammars

FactsExtraction is a surprisingly hard problem with many different approaches each having their own trade-offs. ExtractorBenchmarks are an empirical method to assess the performance and characteristics of an extractor.
