KNIME URI Resolver

Vernalis File IO extension for KNIME Workbench version 1.30.1.v202103301200 by Vernalis (R&D), UK

A column of KNIME URIs is resolved to their absolute paths. If the incoming column is a URI column, then the output is a URI column of file: URIs, otherwise it is a string column of absolute file paths

  • knime://knime.mountpoint/path/to/file - relative to the current mountpoint (repository) as the workflow
  • knime://knime.workflow/path/to/file - relative to the current workflow
  • knime://knime.node/path/to/file - relative to the current node (NB this will be this 'KNIME URL Resolver' node!)
  • knime://MOUNT-ID/path/to/file - Absolute path - NB this is likely to fail to resolve to a local file path unless the MOUNT-ID is 'LOCAL'

This node was developed by Vernalis Research (Cambridge, UK) . For feedback and more information, please contact knime@vernalis.com
