valid_from dates across every wired upstream and emits them as a list of synthetic dated properties.
Pair with Each (Loop Properties port) when you need to derive one target dated property from two or more source dated properties — a change in any source’s timeline should produce a new entry in the target’s timeline.
Inputs
- Data — variadic. Wire any number of upstream nodes (typically
Attributenodes pointing at the source paths, but any node emitting dated properties works). Every incoming timeline contributes itsvalid_fromdates to the union.
Output
- Result — a list of synthetic dated properties, one per unique
valid_fromacross all inputs, sorted descending. Each entry has bothvalueandvalid_fromset to the date. Feed this intoEachon theLoop Propertiesport to iterate per cutover date.
Inside the loop
Inside theEach subgraph, AtMoment falls back to the loop’s each_valid_from when its Date port is unwired — so reading each source at the current cutover date needs no extra wiring.
