UML

DataClassAnnotation entity

This annotation records a possible data class match with the data analyzed by the survey action service.

DataClassMatch relationship

This relationship identifies the matching data class and the degree to which the data values conformed to the specification in the data class.

  • threshold records the percentage of matching values.
  • method records the analysis method used. For example, was every value matched or a sampling technique used? This may affect the resulting confidence of the steward when they confirm the match using the DataClassAssignment relationship.
