0610 Annotations¶

The Annotation entity captures the discovered characteristics of an asset.

Annotations are created by the analysis steps in the discovery service. The attributes of the annotation capture the details of the discovery processing. The subclasses of Annotation capture specific details of the discovered metadata. Each annotation is linked to the discovery analysis report it was generated from. It also links to each asset that the annotation relates to. Strings are used in many of the attributes to keep the model open for discovery service developers and the tools that process them.

• annotationType - descriptive string that acts as an identifier for the specific annotation type. This is a simple means to sub-type any one of the annotation subclasses.
• summary - a human-readable string to describe the annotation.
• confidence - an indicator of the certainty that the annotation is correct.
• expression - this attribute is used to provide more detail on how the asset is related to the annotation.
• explanation - another description field to assist human analysts reviewing the discovery results.
• analysisStep - identifier of the step in the discovery service that detected the annotation.
• jsonProperties - the properties that were used to initiate the discovery service.
