I'm working on creating a client app for Google Drive (PHP). Referring to Files API (https://developers.google.com/drive/v2/reference/files), although I see the main EXIF metadata, I'm missing some of the frequently used other EXIF parms and IPTC metadata.
EXIF Fields missing: focaldistance, meteringmode,sensortype,exposuremode,exposurebias,Lens &MaxApertureValue.
Also, none of the IPTC metadata are parsed: keywords, category, author, copyright, caption, headline, byline,city, state, country, sublocation
Question: Is there are alternate solution to derive above data for the images stored in Google Drive?
Thanks
