We have a preview of custom metadata for OneDrive Personal available now. We’re definitely interested in feedback on the approach and how apps will use it! https://dev.onedrive.com/misc/custom-metadata.htmMario Mercaldi supported this idea ·Mario Mercaldi commented
Second this - paradigms for pulling resources involve either us keeping a separate resource for filtering (making some kind of relational model file) or the much more preferable approach of having a properties entry for each onedrive item that acts as a collection of key,value pairs.
This would let us query with restrictions on these items instead of having to pull static metadata from every file when we make a request or keep a centralized database file and constantly run into concurrency issues.
I'm working on a large project at the moment and would like to incorporate OneDrive support in addition to the current Google Drive support; the only hang-up is there isn't a place for files to store custom metadata.
