Clarifications

1 If provided, this supplies a general explanation of the data provider's knowledge about the lineage of the dataset being described.

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

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

Example(s)

  • Consider a data set 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.
