Scalar Flow - modelint/shlaer-mellor-metamodel GitHub Wiki

From a relational perspective, the internal structure of a scalar value is opaque. It can only be accessed by user defined type specific operations. An example Scalar Flow might communicate an integer value or a GPS location or a video image or any other arbitrarily complex (or simple) unit of data.

The definition of a Scalar is outside the scope of the metamodel domain. (We'll need to specify a Type Definition domain in a separate repository).
