Capability Matrix

This page maps the main OpenPinch capabilities to their primary user-facing surfaces and outputs.

How To Read This Matrix

Stable

Supported as part of the primary package workflow and documented as a public user-facing surface.

Advanced

Supported, but best used after you understand the fundamentals and core workflows. These surfaces are more specialized and often require closer interpretation.

Experimental / partial

Exposed in the codebase, but not yet as fully documented or workflow-polished as the core surfaces.

Package Strengths To Keep In Mind

The practical power of OpenPinch comes from the combination of:

• multiple workflow styles over one analysis engine

• hierarchical zone modeling

• graph-first interpretation support

• typed input/result models for integration into other software

• packaged examples and notebooks that exercise the supported public API
