Legacy Ontology Graph

Automated discovery of hidden dependencies in unstructured COBOL copybooks.

Production Context

Integration with Mainframe Modernizer

Visualizes the 'Spaghetti Code' of the mainframe to help architects plan the migration strategy.

The Dependency Nightmare

Mainframe codebases often contain "Ghost Logic"—code that hasn't been executed in 20 years but is still compiled. The Legacy Ontology Graph uses static analysis to build a directed acyclic graph (DAG) of the entire system.

It identifies:

  1. Dead Code: Safe to delete.
  2. God Objects: Critical files that touch >50% of the database.
  3. Hidden Couplings: Variables passed via shared memory spaces.

Commercial Application

This graph is the "Map" for the Mainframe Modernizer. Without it, migration is just guessing. We export this data directly into the Modernizer's UI to generate the "Migration Roadmap."
