Origin Seeker Remediation Governance Action Service

An asset may have an origin classification attached that documents various properties about its origin. The Origin Seeker Remediation Governance Action Service sets up the origin classification on an asset by navigating backwards through the lineage relationships to locate origin classifications attached to the assets in the lineage graph.

Origin seeker is only able to assign an origin to the asset if at least on of the assets in its lineage has an origin classification, and where there are multiple assets If one (and only one) is found, it is assigned to the action target asset.

Figure 2 shows a simple example of origin seeker finding an origin in a no-branching lineage graph.

Figure 2: Origin assigned because one origin classification found

Figure 3 shows the origin coming from multiple branches of the lineage graph, but they are all the same, so the same values can be assigned.

Figure 3: Origin assigned because consistent origin classifications found

Figure 4 shows a case where origin seeker fails because the asset’s lineage shows it to have been derived from multiple origins.

Figure 4: Origin not assigned because inconsistent origin classifications found

Finally the origin is not assigned because there are no origin classifications in the lineage graph.

Configuration

This connector uses the Governance Action OMES running in the Engine Host.

This is its connection definition to use when creating the definition of the governance action service using the Governance Engine OMAS. Note that is does not use configuration properties.

{
   "connection" : { 
                      "class" : "Connection",
                      "connectorType" : 
                      {
                           "class" : "ConnectorType",
                           "connectorProviderClassName" : "org.odpi.openmetadata.adapters.connectors.governanceactions.remediation.OriginSeekerGovernanceActionProvider"           
                      }
                  }
}

Governance Action Settings

When this governance action service is called through a GovernanceAction it supports the following options.

Request Types and Parameters

Origin seeker does not specifically recognize any request types or request parameters.

Action Targets

The asset that needs an origin classification is linked to the governance action as an action target. The unique identifier (guid) can be passed as a parameter when the governance action or governance action process is initiated.

Completion Status and Guards

These are the responses that origin seeker produces:
