workspaceTableGrouping

This reference describes the full structure of workspaceTableGrouping. Paths include nested objects, list items and conditional branches. A branch selected by kind, contract or mode only admits its own properties.

Structure and values

Field	Options / expected values	Description
contract	"WorkspaceTableGrouping@1"	Required. Exact discriminant of this contract variant. Match the literal value shown.
options	Array<closed object>; min length 1; max length 20	Required. Suggested and admitted values for a declared choice.
options[].key	string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u	Required. Stable semantic identifier used by references; changing it changes identity.
options[].label	string; min length 1; max length 4000	Required. Human-readable label displayed in the interface.
options[].columnKey	string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u	Required. Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility.
initialOptionKey	string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u; null	Required. Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility.
maximumGroups	integer; ≥ 1; ≤ 100	Required. Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema.

Reading the contract

A path ending in [] describes each list item; {key} describes each dictionary value. The ↻ marker refers to the same recursive expression. Closed objects reject additional properties. Semantic validation denotes an additional check: matching a type does not make a reference, permission or transition valid. References must resolve in the Model and the current user context.

An older variant cannot accept properties belonging to a newer variant. The compiler checks the version and consistency of the complete Model.

Structural example

This fragment passes the schema for this section. Its business references must be defined in the enclosing Model.

{
  "contract": "WorkspaceTableGrouping@1",
  "options": [
    {
      "key": "client",
      "label": "client",
      "columnKey": "client"
    }
  ],
  "initialOptionKey": null,
  "maximumGroups": 1
}
