Add additional metadata

[mat-l]

Is it possible to add additional metadata to the file which will be uploaded to GridFS, something like the following command is not working:

fileid = depot.create(open('C:/Users/xxx/Documents/mongodb/mineral.jpg', 'rb'),
                      metadata=dict(
                          {"tag": "image", "tag2": "videocut", "tag3": "jpg"})
                      )
