The DESC statement allows obtaining a description of the elements in the Virtual DataPort server. If you run “DESC VQL REST/SOAP WEBSERVICE <web_service_name>” query in the VQL shell, it would give you the dependency information within it. For more information, please refer to the [Describing Catalog Elements](https://community.denodo.com/docs/html/browse/7.0/vdp/vql/describing_catalog_elements/describing_catalog_elements).
The data lineage stored procedure, VIEW_DEPENDENCIES(), can be exposed to API by publishing a view created on top of them. In order to do so, please follow the steps below:
1. Create a view on top of the VIEW_DEPENDENCIES stored procedure: `CREATE OR REPLACE VIEW view_name AS SELECT * FROM view_dependencies();`
2. Publish the new view as a REST web service
3. Deploy the new web service
4. Access this web service using a URL similar to this:
You can find this URL in the Web Services Container by going to Tools > Web Services Container.
