Talend
This article outlines the integration with the Talend connector, enabling metadata management through crawling and lineage building (automatic and manual). The connector crawls Talend .item files and maps the extracted metadata to the Data Catalog.
The connector establishes connectivity to Talend through an External Workspace, including Azure DevOps Repo, NFS, and GitHub Files. Connection configuration requires a Workspace Connection ID, an optional Context Params File Path, and read access to .item files for crawling.

Prerequisites
The following are the prerequisites to establish a connection:
Service Account User Permissions
It is recommended to use a dedicated service Token to establish the connection to the data source, configured with the following minimum set of permissions.
Crawling
Datasets
READ permission for .item files
Connection Configuration Steps
Users are required to have the Connector Creator role in order to configure a new connection.
Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for Talend, and complete the required parameters.
Connector Type
By default, "Talend" is displayed as the selected connector type.
Credential Manager*
Select the desired credentials manager from the drop-down list. Relevant parameters will be displayed based on the selection.
Supported Credential Managers:
OE Credential Manager
AWS Secrets Manager
HashiCorp
Azure Key Vault
For more details, click here.
License Add Ons
Select the checkbox for the Auto Lineage Add-On to build data lineage automatically. For more details, click here.
Connector Name*
Enter a unique name for the Talend connection
(Example: "Talend_ETL").
Connector Environment
Select the environment (Example: PROD, STG) configured for the connector. For more details, click here.
Connector Description
Enter a brief description of the connector.
Workspace Connection Id*
Enter the connection ID of the Talend workspace to be accessed by the connector. The workspace connection ID identifies the workspace from which the Talend .item files are accessed for metadata crawling and automated lineage.
Context Params File Path
Enter the path to the context parameters file used by the Talend workspace connection. The file provides the context parameters required to access and process the Talend workspace resources.
Admin Roles
Admin Roles*
Select one or more users from the drop-down list for Integration Admin and Security & Governance Admin. All users configured in the security settings are available for selection.
Bridge
Select Bridge*
If applicable, select the bridge from the drop-down list.
The drop-down list displays all active bridges that have been configured. These bridges facilitate communication between data sources and the system without requiring changes to firewall rules.
After entering all connection details, the following actions can be performed:
Click Validate to verify the connection.
Click Save to store the connection for future use.
Click Save & Configure to apply additional settings before saving.
The saved connection will appear on the Connectors home page.
Manage Connector Operations
