BogProvider (“Sys Def Provider”) is child container property in a NiagaraNetwork. The API interacts with this component to query about the “Sys Def” hierarchy, and persists this definition. Storage includes two options to store all Sys Def nodes: either BOG, i.e. the station .bog, as the default (using child ProviderStation components), or Orion (in Orion database). Sys Def is chiefly of interest to NiagaraAX developers working with the API.
