Name and description for identification - Mathematical expression using supported operators and functions - Units of measurement and formatting preferences - Dataset associations for coefficient lookups **Mathematical Expression Support**: - Basic arithmetic operators (+, -, *, /) - Nested parentheses for complex calculations - References to other indicators by ID - Dataset coefficient lookups with key-value mappings - Support for environmental calculation standards **Validation**: - Syntax validation for mathematical expressions - Circular dependency detection - Unit compatibility checking - Dataset reference validation Requires site manager permissions as indicators affect organizational data calculations and reporting accuracy. ## OpenAPI ````yaml https://app.azalt.co/api/v1/openapi.json post /indicators openapi: 3.0.3 info: title: Erguvan Public API version: 1.0.0 servers: -
