Interface DataSpaceCoordinates

What a data space source reads (PLAN §11.25): a class of a data space, as the host's query builder queried it. Cube never reads either lambda: the host's editor writes both, and the emitter passes relation through. A source added from the source dialog has neither until its editor applies one: it is unset.

interface DataSpaceCoordinates {
    dataSpace: string;
    entity?: string;
    executionContext: string;
    query?: JsonObject;
    relation?: JsonObject;
}
