Preparing data for IBM Manta Data Lineage

To add data to the lineage repository, create data source definition, and create metadata import.

Required permission

You must have the following user permission:

Manage data lineage

Prerequisites

You must install the IBM Knowledge Catalog service with the IBM Manta Data Lineage service enabled.

You need a project to store the imported metadata for the data assets. For more information, see Creating a project.

Preparing data to populate lineage repository

Before viewing the lineage, you need to populate your data lineage repository the following way:

Create a data source definition and a connection.

A data source definition is an asset that functions as a unique stable identifier for the location of a data source such as a relational database. Data source definitions use endpoints to identify the data source. For most data source types, an endpoint is the combination of the hostname or IP address, the port number, and the database name or instance identifier. For more information and a procedure, see Creating a data source definition from the Data source definition list.

A connection is used to connect to the external data source. See, Adding platform connections. To view a list of supported connectors for data lineage, see Supported connectors for lineage import.

The connection assignment to a data source definition is done automatically. When creating connection first and, then, a data source definition, the assignment might take a longer time.

Navigate to your project and create metadata import. For more information, see Creating a metadata import asset and importing metadata.
After successful metadata import job, go to Data > Data lineage > View lineage tab to check if your data is visible in the repository tree.
