Attach Time-sliced Metadata to Eloquent Models
"Multiplex is a Laravel package to attach time-sliced meta data to Eloquent models.
The metadata in Multiplex has a timestamp that defines validity. This allows changes to be tracked and planned. You can inspect all metadata on your model at a specific point in time and Multiplex will by default only give you the most current.
Since Multiplex is storing the metadata in a polymorphic table, it can easily be plugged into existing projects to expand properties of your models. This even works without removing the relevant table columns of your model: They are used as a fallback.
And it’s low profile: If you don't like it, just remove the
HasMetaTrait and everything is back to normal."
