Add duplicate-checking via checksum comparison

Reported by: mgranger Assigned to: mgranger
Priority: major Milestone: ThingFish 0.3 - The "N-Robot" Release
Component: ThingFish Keywords: thingfish duplicate-checking checksum
Cc: Depends on:

Description

Since every resource stored in ThingFish has an associated checksum, it would be easy to notice when someone was uploading a duplicate resource, and just re-use the currently-extant one. However, there are some complications that arise when you do this:

  1. Who 'owns' the resource?
  2. How do you handle updates to the resource?
  3. Is there any special treatment for the case where the ACL specified by the original owner doesn't allow access to the second uploader?

That said, this would still be useful functionality, especially in several of our planned applications, so we still want to figure out how to implement it.
