Data of manifest.rdf could not be read

I realize that this message was presented in 2014 and closed with only one comment in 2016. But I need to resurrect the query because it just now appeared on one of my spreadsheets. What I need to know is what this error message means.

@ericn - (1) Please don’t “post as wiki”. (2) More importantly, this makes no sense at all. Please read about how to ask a good question, and then edit your question to provide all relevant information. Thank you.

Came across this info from the OpenOffice site.

“.rdf is storage of meta-data in ODF file.
It stores properties, custom properties and user defined field data.”

Hi, i gave an answer on open office french website and i got a message that i’m a gravedigger who uncover an old post of ten years of age… (but without real solution and not locked too…).

If it’s for a “base.odb” file and your form work after opened with this error, you can fix it with “editing”. Open it for editing and just after error message, close it. It will ask you to record your form beacause it has changed (even if you did not changed anything). Record it and your error will disappear for ever.
