Hi:
Although the SUBJECT and AUTHOR and TITLE options exist for RTF and PDF, ODS HTML and ODS CSV and ODS TAGSETS.EXCELXP do not have options or suboptions that populate these Excel properties.
If there is HTML or XML, according to the Microsoft specification that would populate these properties, then you'd have to figure that out in the Microsoft documentation. But, by default, it looks like ODS does not have a direct way to impact these properties.
