The inverse of [as_bpmn()], so a process drawn in any BPMN tool becomes a table blockr.process can run: draw in Camunda Modeler, [read_bpmn()] the file, `bpmn_to_table()` the model, drop the table into a process block.
Value
A tibble with columns `task`, `name`, `role`, `depends_on`, `script`, `collection`, `parent`, `join`, `sequential`.
Details
What the inversion does: - Events and gateways disappear into the `depends_on` grammar: a task behind a converging gateway depends on everything flowing into that gateway (`join` records the kind – exclusive/inclusive merge becomes `"any"`, a complex gateway named `"k of n"` becomes `"n=k"`); a task behind a diverging gateway depends on the gateway's input, qualified by the branch label (`"validate:yes"`). Chains of gateways resolve through. - Lanes become `role`; a lane-less script/service/send/receive task becomes `role = "system"`. - Multi-instance activities are grouped back into containers: each connected run of multi-instance nodes gets a group row (`collection = "item"`, a placeholder), its members point at it via `parent`, and edges crossing the group boundary are lifted onto the group row – the inverse of the lowering [as_bpmn()] performs.
The result is a **scaffold**, not a finished definition: fill in `collection` names, check the quorums, and add `script` values where the XML did not carry them (files written by [write_bpmn()] do).
