• Types: string, int, decimal, boolean, date
• Built-in functions: sum, count, min, max, avg
• Operators: | (superposition), .. (ranges), * (cardinality), ^ (parent reference)
• Comments: // single line comments
• Strings: "quoted strings"
• Numbers: integers and decimals

Example

schema Invoice {
  status: 0.6: "paid" | 0.3: "pending" | 0.1: "draft",
  amount: int in 100..10000,
  line_items: 1..5 * LineItem,
  total: = sum(line_items.amount),

  assume if status == "paid" {
    amount > 0
  }
}

dataset TestData {
  invoices: 100 * Invoice
}
