I try to update the medatadata informations (EXIF) for images in a folder. Via the StorageRepository I can read the metadata from file system. I now want to put the recieved information into the TYPO3 database. I think I found the corresponding mysql table called sys_file_metadata where the informations are stored for each file id.
My question now is, if there are any functions or methods to put the recieved metadata into the database or do I have to put it in via a mysql query?
Just use the datahandler for this. https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Typo3CoreEngine/UsingDataHandler/Index.html
And indeed it's stored in sys_file_metadata
