String to URI

Converts strings in a column to URIs. The strings must contain valid URI syntax. You can choose to either replace the selected column with the URI column or append a new URI column.

For local files, you can optionally check if the files referenced by the URIs exist and abort execution if any file is missing.

Options

Column selection: Column that will be converted. It has to contain a string with correct URI syntax.
Fail if file does not exist (only applies to local files): Checks if the files referenced by the created URIs are existing and will abort if one is not.
Append or replace: Choose whether to append a new column or replace the selected column.
New column name: Name of the appended column.

Input Ports

: Input table containing a string column to be converted to URIs.

Output Ports

: Output table with the string column converted to URIs or a new URI column appended.
