KNIME Server Connector

This node connects to a KNIME Server via REST. The resulting output port allows downstream nodes to access the Server workflow repository as a file system, e.g. to read or write files and folders, or to perform other file system operations (browse/list files, copy, move, ...).

Path syntax: Paths for KNIME Server are specified with a UNIX-like syntax, for example /myfolder/file.csv, which is an absolute path that consists of:

A leading slash (/).
Followed by the name of a folder (myfolder), followed by a slash.
Followed by the name of a file (file.csv).
