additions we will probably need to storage api endpoint

[vsoch]

• We need to decide on default permissions for objects, and have functions to define/ change, etc.
• We also need an easy way to add metadata per image. This (functionally) is implemented, I'm just not sure about what is the best user flow. The goals would be:

1. still use batch processing for uploads as much as possibl
2. have the image metadata added at the same time created
3. Not be (too annoying) for usage.

Option 1 is to have the user create the image, and then essentially do an image.update(fields=fields) for each. This is how it would be done, given coming back at a later date and updating the metadata. I don't like this for creation because, what if the user forgets? Mixes up stuff?

Option 2 is to let the user specify image / text fields based on another argument to the function for a dictionary lookup, eg:

images_fields = { "image1.dcm": [  {'Modality':"CT"}  ] }
