Class InstanceAuditHeader

  • All Implemented Interfaces:
    Serializable
    Direct Known Subclasses:
    Classification, InstanceHeader
    public abstract class InstanceAuditHeader
extends InstanceElementHeader
    InstanceAuditHeader manages the attributes that are common to classifications, entities and relationships. We need to be able to audit when these fundamental elements change and by whom. Thus they share this header. The fields in this header are managed as follows:
    • Type identifies which TypeDef defines the type of concept/thing that this instance represents and controls the properties that can be stored in the instance.
    • InstanceProvenanceType defines the type of metadata collection that this instance originated from.
    • MetadataCollectionId defines which metadata collection that this instance came from - that is its home.
    • MetadataCollectionName defines the display name for the home metadata collection.
    • InstanceLicense defines a specific license that applies to this instance - null means no restrictions.
    • CreatedBy contains the userId of the person/engine that created the instance. This field is set up when the instance is created and not changed. It typically indicates who is the owner of the element and hence who has update rights.
    • UpdatedBy contains the userId of the person/engine that last updated the instance. This field is set automatically by the open metadata repository when the update happens.
    • MaintainedBy contains the list of userIds of the person/engine that are responsible for maintained this instance. Null means that the maintainer is the creator.
    • CreateTime contains the Date/Time when the instance was created. It is set automatically by the open metadata repository when the instance is created.
    • UpdateTime contains the Data/Time when the instance was last updated. It is also set automatically by the open metadata repository when the update happens.
    • Version is a numeric count of the updates to the instance. It is used by the open metadata repositories to ensure updates to reference copies of the instance are applied in the right sequence. The home open metadata repository (where the create an all subsequent updates happen) maintains the version number.
    • CurrentStatus indicates the status of the instance. It is initialized by the open metadata repository to the first status defined in the TypeDef. After that, it is the actions of the consumers of the metadata (typically the Open Metadata Access Services (OMASs)
    • StatusOnDelete is populated when the instance is deleted and is se to the status when the deleted was called - it is used set the status if the instance is restored.
    • MappingProperties is used by connector implementations that are mapping between an existing repository and open metadata. It provides space for the connector to stash identifiers and other values that help them to map instances stored with the open metadata equivalent. These values should be maintained by the master repository and stored by any repository that is saving the reference copy.
