Open Ontology
The operational layer you can read, run, and change.
Define the objects, relationships, rules, and work that make an organization run. Compile them from readable source into a live system with temporal facts, queries, governed actions, and an explanation for every outcome.

One model, from source to work
The ontology is executable.
A staffing team defines its domain in Lisp embedded in Markdown. The compiler produces a typed artifact. The runtime stores facts, evaluates constraints, and surfaces missing evidence as work. These forms follow the staffing example in this repository.

(define-entity Employee
(:field [employee/first-name String {:required true}])
(:field [employee/last-name String {:required true}])
(:field [employee/email String])
(:field [employee/status String]))
(define-entity Placement
(:field [placement/employee (Ref Employee)])
(:field [placement/status String {:required true}]))An open operational contract
Your model should belong to you.
Open Ontology brings the idea of an operational ontology into an inspectable, source controlled system. Domain definitions, fact history, and action boundaries stay visible to the people who build and operate it.
Grounded state
Keep facts and relationships in a time traveling triple store. Use Datalog to ask what is true and what changed.
Governed action
Run mutations, actions, and workflows through explicit runtime boundaries with traceable results.
