OData connection

You can create a connection asset for OData in a project or in a catalog. If you have a Watson Machine Learning service instance, you can promote the connection asset from a project to a deployment space. 

The OData (Open Data) protocol is a REST-based data access protocol. The OData connection reads data from a data source that uses the OData protocol.

Supported tools

These tools support OData connections:

  • Data Refinery
  • SPSS Modeler


  • For Data Refinery, you can use this connection only as a source. You cannot use this connection as a target connection or as a target connected data asset. 
  • For SPSS Modeler, you can use this connection only to import data. You cannot export data to this connection or to an OData connected data asset. 

Supported versions

The OData connection is supported on OData protocol version 2 or version 4.
