Programmatically add/associate metadata to any file -

-

i'm building tool export files learning management system , store files somewhere s3. need keep track of pieces of information files relate system they're coming (e.g. course name, academic term, student's name/id). file types vary drastically, don't want make accommodations store metadata based on filetype (like pdf or doc).
