# Ontology engineering
## MicroSim spec
- **Recommended sim type:** graph-network
- **Microsimmability score:** 36/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Nodes` (number of nodes)
- `Edge density` (fraction of possible links present)
- `Edge cost` (weight scale on links)
### What animates
A network of nodes and weighted edges lays out on the canvas; a path or flow is traced and re-routed as topology and costs change.
### Learning objective
Relate routing, critical paths, and delay to network topology and costs.

## Concept summary
In [[Computer_science|computer science]], [[Information_science|information science]] and systems engineering, ontology engineering is a field which studies the methods and methodologies for building ontologies, which encompasses a representation, formal naming and definition of the categories, properties and relations between the concepts,...
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Ontology engineering
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render graph-network; respond live.
}
```
