# Naming Conventions

Identifier capitalization has no language-defined meaning.
Values, constraints, schemas, and derived configurations are all expressions of the same kind.

For readability, the following conventions are recommended:

- Object values: `lower_snake`
- Functions: `lowerCamel`
- Primitives, schemas, and abstract constraints: `UpperCamel`

```dcdl
Port = Int & >= 1;
Service = { port = Port; };
service = { port = 8080; } as Service;
mkService = (port: Port) => { port = port; };
```
