Configuring Watson Knowledge Catalog connector

A utility script is provided to simplify and automate the Watson™ Knowledge Catalog connector configuration. Alternatively, you can configure the Watson Knowledge Catalog connector manually.

Before you begin

Collect details of the IBM Cloud® Watson Catalog instance. The details that are required can vary depending on whether the IBM Watson® Catalog is on Cloud or On-premise.

To add IBM Cloud Watson Catalog details to the IBM Spectrum® Discover, obtain the following details:

  1. Obtain the API key for accessing the Watson Knowledge Catalog application. To access WKC application on the IBM® Cloud, Log in to IBM Cloud and select Create an IBM Cloud API key.

  2. Export or copy the key.
  3. Copy the base URI of your WKC instance. For IBM Cloud, the WKC instance URI is based on the geographical location.

To add the IBM on-premises Watson Knowledge Catalog details to IBM Spectrum Discover, obtain the following details:

  • Obtain the values for the following Watson Knowledge Catalog (WKC) parameters from the systems administrator of the On-Premises instance:
    • WKC_USER
    • WKC_PASSWORD
    • WKC_BASE_URI
    • WKC_AUTH_URI

To successfully export document-related metadata from IBM Spectrum Discover to the Watson Knowledge Catalog , WKC application must have access to the original documents. This step is achieved by using either a linked or a non-linked data source. Exporting metadata from a linked data source indicates that both Watson Knowledge Catalog and IBM Spectrum Discover have access to the original data source location, eliminating the need to copy the original files.

Exporting metadata from a non-linked data source is used when Watson Knowledge Catalog does not have access to original IBM Spectrum Discover data source location. In this case, IBM Spectrum Discover copies the files that are associated with the export metadata to a location where the Watson Knowledge Catalog service can access these documents. A Watson Knowledge Catalog Cloud Object Storage (COS) connection must be available to export from non-linked data sources.

You must know the details of linked or non-linked data sources before you start configuring the WKC Connector. For more information, see Mapping similar source connections in Watson Knowledge Catalog.
