Stable IDs, explicit types

const inspection = {
  concepts: [
    {
      id: "roof_inspection",
      name: "RoofInspection",
      description: "An inspection before panel installation",
      fields: [
        {
          id: "reference",
          name: "Reference",
          description: "Explicit inspection reference from the source",
          type: "text",
        },
      ],
    },
  ],
  relations: [],
};

Concept, field and relation IDs begin with a lowercase letter and contain lowercase letters, digits or underscores, up to 64 characters. Names are display labels; IDs are the stable interface.

Scalar dialect

Type	Representation
`text`	String
`integer`	Safe integer
`decimal`	Decimal string, normalized without floating point
`money`	`{ amount: "50000", currency: "INR" }`
`boolean`	Boolean
`date`	Valid calendar date
`timestamp`	Offset-aware timestamp with seconds, up to six fractional digits
`enum`	One of the declared string values

optional controls whether a field may be missing. nullable separately permits a value of null. Timestamps support years 1–9999. Timestamp equality currently uses the preserved typed string representation.

Relationships

A relationship declares a stable ID, name, source concept and target concept. Set max: 1 for the supported single-target constraint. Read inclusion is bounded to one hop.

Additions and compatibility

The alpha supports new concepts, optional additions to existing concepts and relationships. Renames, changed meanings/types, required field additions on existing concepts and destructive changes are rejected. It does not emit business-table DDL.
