API

It is also possible to access the GraphML information via a Pentaho Server API. There are REST endpoints available to retrieve the lineage related artifacts.

Below are some example curl commands which exercise the REST endpoints available on the Pentaho Server. These calls use basic authentication. For more information on the various ways to authenticate with the Pentaho Server, see Authenticate with the server before making service calls in the Pentaho REST API documentation.

For more detailed information about the REST endpoints available, you can go to the Pentaho Wiki to view the attached Enunciate file.
