ContX IQ: link the _Application node to other data in the IKG.

When a new application with new credentials is created, nodes are created in the IKG. This use case explains how to link the Application node to the ingested data.

ContX IQ: link the _Application node to other data in the IKG.

Create a relationship between the _Application node created with a new Application and new AppAgent configurations and the ingested data.

Use case

When a new Application with new credentials is created, _Application and _AppAgent nodes are created in the IKG.

In order to create a relationship between these nodes and the ingest data, a CIQ write query can be used.

This will allow the use of the _Application as an authenticated subject.

In this case, a HAS_AGREEMENT_WITH relationship is created between the _Application node and a company node.

Requirements

- ServiceAccount credentials created in the IndyKite Hub for your organization.

- AppAgent credentials created in the IndyKite Hub, using the REST endpoints or using Terraform for your Project / Application.

Steps

1. Using the AppAgent credential as API Key (name: X-IK-ClientKey), ingest data in your IKG (IndyKite Knowledge Graph) using the script provided.

2. Using the ServiceAccount credential as Bearer token, create a CIQ Policy.

3. Using the ServiceAccount credential as Bearer token, create a CIQ Query.

4. Using the AppAgent credential as API Key (name: X-IK-ClientKey), run a CIQ Execution.

5. Delete your configuration.

Step 1

Ingest the nodes needed for this use case.
