Protocol
From Schemalet Wiki
The Protocol class defines parameterizable descriptions of methods; each protocol has a unique name within a dataset. Each Protocol_application can define the Observable_features it can observe as well as the optional Parameters (not shown, to be discussed?). For instance: SOP for blood pressure measurement used by UK biobank. This class maps to FuGE/XGAP/MageTab Protocol, but in contrast to FuGE it is not required to extend protocol before use. Note that the FuGE's mechanism of parameters (for protocol) and parametervalues (for application) is not shown. Has no equivalent in PaGE.
