Hi Jasmin, please find my scenario below.
1. User1 uploads a PDF, which is stored in content space as a document content.
2. User2 downloads it by adding some extra information to it with help of a designed form, which includes original content document and specified fields to enter the data
3.Finally, the new form is stored in the repository as a new content.
The original content document is a PDF including scanned media, the second content is another PDF including that media and the information about it.
Thank you,
