Clarifications

1If provided, each <DRM Process Step> component of the <DRM Lineage> instance supplies information about an event in the creation process for the representations specified by the scope.

2If provided, each <DRM Source> component of the <DRM Lineage> instance supplies information about the source data used in creating the representations specified by the scope.

Example(s)

  • Consider environmental data representing a transmittal containing a polygonal terrain representation that was derived from a DTED representation. The <DRM Lineage> instance for the <DRM Transmittal Root> instance of this example transmittal might have a <DRM Process Step> component describing the polygonalization process as well as a <DRM Source> component corresponding to the DTED representation.
