ontology

Ontology

This subtree contains SemiKong's semiconductor ontology and knowledge-graph work, imported from semicont and now housed inside the broader SemiKong repository.

Its purpose is to provide an open semantic foundation for semiconductor knowledge that can support interoperability, provenance, validation, and downstream model- or workflow-level applications.

We intend to contribute the SemiKong ontology work into the broader SEMI standards and interoperability effort where that alignment is useful and appropriate.

What Is Here

• ontology modules in Turtle under ontology/ontology/
• architecture and methodology docs under ontology/docs/
• SHACL shapes under ontology/shapes/
• examples under ontology/examples/
• curation and ontologist workflow materials under ontology/ontologist/

Design Intent

The ontology work is intended to make semiconductor knowledge:

• interoperable across organizations and systems
• auditable through explicit provenance
• reusable across practical workflows
• modular enough for public core plus private extensions

This aligns with the original semicont direction and now serves as the ontology side of SemiKong's combined model-plus-ontology repository.

How To Use

From the repository root:

make -C ontology audit
make -C ontology benchmark
make -C ontology export-agentic

Current Shape

The imported ontology currently includes:

• shared and physics foundations
• industry-layer modules such as integrators, EDA, foundry/IDM, OSAT, WFE, materials, and supply chain
• validation shapes and curation assets

The canonical semantic source remains the Turtle content under ontology/ontology/.

License Note

The imported ontology subtree includes its own ontology/LICENSE. The repository as a whole is MIT-licensed at the top level, but ontology assets may also carry their own preserved licensing and provenance context from the imported source.
