I believe this is the discussion @WHFarms was referring to: Generalizing Log-based Asset Attributes
To echo what @Farmer-Ed said: I wouldn’t wait around for changes to be made before you start using farmOS @WHFarms. Either help them be implemented or find a workaround (or a different system).
We are currently working towards farmOS v4, but there is no budget to implement the log-based attributes feature. Perhaps someone will offer to help in the future (v5? v6?)… or perhaps they won’t.
