Clarifications

1 This value is TRUE if any aspect of the data content intentionally deviates from the available source data - that is, was “made up” out of thin air; fictional is FALSE otherwise.

2 This optional accuracy statement applies, for the scope of the given <DRM Data Quality> instance, to <DRM Property Value> instances that are attached to <DRM Feature> and <DRM Geometry> instances, or are contained in <DRM Property Table> instances.

3 This is an optional statement of logical consistency.

4 This is an optional statement of completeness.

5 This optional statement may alternately be expressed numerically through the use of EAC_ABSOLUTE_HORIZONTAL_ACCURACY.

6 This optional statement may alternately be expressed numerically through the use of EAC_RELATIVE_HORIZONTAL_ACCURACY.

7 This optional statement may alternately be expressed numerically through the use of EAC_ABSOLUTE_VERTICAL_ACCURACY.

8 This optional statement may alternately be expressed numerically through the use of EAC_RELATIVE_VERTICAL_ACCURACY.

9 If provided, this specifies either

  1. information about the events and/or source data used in constructing the data set to which given <DRM Data Quality> instance applies, or
  2. lack of knowledge about lineage.

Example(s)

  • Description of the level of data quality for the <DRM Feature> instances within a particular thematic layer, such as vegetation.
