Ontopoiesis
Lint, test, diff, and CI for OWL 2 ontologies, from a single command line.
Ontopoiesis builds an OWL/XML ontology into a Cypher-queryable
Ontoplexis
projection, then runs the day-to-day workflows around that one artifact:
query, lint, test, diff, impact analysis, render, migrate, and export.
Quality gates are plain .cypher files that fail when they return rows, so
teams extend the rule set the way they write dbt tests. The stock rules provide
targeted structural checks, while the documented case studies also show
case-specific analysis and distinguish demonstrated defects, modeling risks,
and policy-backed findings from compatibility facts and clean controls
(why this exists).
Scope
Ontopoiesis owns command-oriented workflows and their conventions. It does not
own the OWL/XML parser or graph projection model; those belong to Ontoplexis.
It also does not parse formats other than OWL/XML, resolve imports or reason
in-process, or provide typed OWL construct models. Optional convert,
resolve, and reason commands delegate those preprocessing jobs to a
user-provided ROBOT jar.
Relationship to the stack
OWL/XML --> Ontoplexis projection --> Ontopoiesis workflows
Ontopoiesis depends on Ontoplexis. Ontophora is a separate sister library that provides typed OWL 2 construct records; it is not a dependency of this CLI.
