What is campsismod?

The model layer under Campsis, renamed in step with it and increasingly JSON-addressable.

Campsismod holds the model object layer for the Campsis pharmacometric simulation suite: reading, editing and writing model definitions that Campsis then simulates. Its recent releases track a single programme, adding a JSON route into model objects and then renaming the whole API to snake_case in 1.4.0, a week before Campsis 1.9.0 did the same. Release notes are terse issue lists, so the reasoning behind each change has to be read from the sibling package.

What is rollupTree?

The recursive-computation engine under massProps grows the accessors its consumer needed

rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.

2.5

The model layer under Campsis, renamed in step with it and increasingly JSON-addressable.

◆ Current state

Campsismod holds the model object layer for the Campsis pharmacometric simulation suite: reading, editing and writing model definitions that Campsis then simulates. Its recent releases track a single programme, adding a JSON route into model objects and then renaming the whole API to snake_case in 1.4.0, a week before Campsis 1.9.0 did the same. Release notes are terse issue lists, so the reasoning behind each change has to be read from the sibling package.

◆ Where it's heading

This package moves when Campsis needs it to move. The JSON constructor landed here in 1.3.0 and reached Campsis datasets a day later; parameter uncertainty generation was handed down from Campsis in that package's 1.6.0; and the snake_case migration started here before propagating up. That ordering makes Campsismod the place where suite-wide interface decisions are taken first, even though the visible payoff shows up in Campsis.

◆ Prediction

Expect Campsismod to keep absorbing model-level responsibilities that Campsis currently handles, and to extend the JSON mapping to whatever parts of the model object it does not yet cover. The entries give no signal on a 2.0, and with the rename already spent there is little reason to expect one soon.

The recursive-computation engine under massProps grows the accessors its consumer needed

◆ Current state

rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.

◆ Where it's heading

The package develops in response to its one visible consumer. The 0.4.0 accessors appeared in January 2026 and massProps switched to them thirteen days later; 0.4.1 then fixed missing column names in the setters, which is the kind of defect only real use surfaces. Before that, 0.3.0's default_validate_dag() extended validation past strict trees to directed acyclic graphs, widening what structures the engine will accept.

◆ Prediction

On the established pattern the next release will be whatever massProps needs next, discovered by using it. A DAG validator suggests non-tree structures are in scope, but nothing in these notes says that path is being pushed further.
