Ontology.Core

A production-ready prototype graph runtime for healthcare and beyond

Buffaly is a neurosymbolic platform for building large, explainable knowledge graphs and running language-aware inference over them. It is powered by Ontology (a prototype graph runtime) and ProtoScript (an executable language for defining prototypes, rules, and functions).

This repository contains the ontology runtime and its parser/simulation projects.

Scope

This repository is part of the open-source split of our platform. It does not include several commercial components (partner-only datasets, agentic tooling, and medical extensions).

✨ Key capabilities (Ontology runtime)

Feature	Why it matters
🧬 Prototype graph	Typed nodes, property edges, child collections, and multi-parent TypeOf inheritance.
🧭 Graph navigation	Structural comparison, categorization checks, and path/parameterization primitives.
🧰 Interop	Native-value prototypes and reflection utilities for bridging CLR values into the graph.
🧪 Simulation helpers	Runtime support for downstream parsers, interpreters, and workflows.

What This Repo Owns

1. Ontology - core runtime types (Prototype, properties, children, inheritance, conversions).
2. Ontology.Parsers - parsing utilities for ontology data.
3. Ontology.Simulation - simulation/runtime support utilities.

Solution

• Ontology.Core.sln

Current solution membership:

• Ontology
• Ontology.Parsers
• Ontology.Simulation

🚀 Quick start (as source)

using Ontology;

Initializer.Initialize();

Prototype animal = Prototypes.GetOrInsertPrototype("Animal");
Prototype dog = Prototypes.GetOrInsertPrototype("Dog", "Animal");
Prototype fido = dog.CreateInstance("Fido");

Console.WriteLine(fido.TypeOf(animal)); // True

🛠 Build

The split repos are designed to sit as siblings on disk so Scripts\update_dlls.bat can copy DLLs between ..\ontology-core, ..\protoscript-core, and ..\buffaly-nlu. If you clone into different folder names, update the paths inside Scripts\update_dlls.bat.

From repo root:

Scripts\update_dlls.bat
dotnet build Ontology.Core.sln

🧪 Tests

There are currently no repo-local *Tests*.csproj projects in this repo. ProtoScript unit/integration tests live in ProtoScript.Core (ProtoScript.Tests and ProtoScript.Tests.Integration).

📦 Dependency model

• Shared binaries are resolved from local lib\ and Deploy\.
• Scripts\update_dlls.bat refreshes DLLs used by local builds.
