Hi everyone,
when doing some text mining, I would like to know the date of each article after tokenization. However, I only receive the text columns in the end, on which the sentiment dictionary is applied. Is there any possibility to keep the date column or add it again on the way?
Here is my code:

    Hi @Titzaaa

    I can´t run the process since you retrieve information from some repository on your computer.
    You could add the Generate ID Operator after the retrieve and the use that ID to join your results to your first DataSet.

    Hi @MarcoBarradas
    unfortunately, when putting the Generate ID Operator directly after the retrieve, the ID also does not survive the rest of the process (the text mining and tokenization).
    How can I solve that problem?
    Many thanks!

    use the role operator before you start your document workflow. You can actually add anything you want (so don't be distracted by the dropdown options). If you name your datefield for instance date, it becomes a special attribute and it will travel along your process as metadata. Just ensure you do not exclude special data in your process as it will be gone again then.

    Hi Kayman,
    thank you for your reply!
    The date goes all along the way until the "Apply Model (Documents)" Operator - there, it gets lost.
    Any suggestions here?
    Thanks a lot!

    Hi @Titzaaa,
    this is almost for sure a bug. @sgenzer can you please create a ticket and assign me?

    fixed in the local dev branch. Will be released with the next version of Operator Toolbox.
