API endpoints for creating, updating and deleting images at runtime

Design

New manifest namespace in DB

This namespace contains all the required information on imported manifests. It will replace the current images namespace.

Folders:

name	description
uid	A unique identifier built from the hash of the manifest URI
uri	URI of the manifest
label	Manifest's label
body	Manifest body
timestamp	Timestamp of last DB entry change
status	Import status. One of pending, ok, error(err_msg), deleted
images	UIDs of referenced images
manifest_hash	Hash of imported manifest

Manifest import / update workflow

1. Download manifest
2. Create hash from manifest
3. If manifest is already in DB and hash is the same, abort. Otherwise:
4. Parse manifest
5. Register manifest in DB (set status to pending)
6. Create puzzles in puzzles/ directory
7. Update root index.json based on information from DB entry

Manifest deletion workflow

1. Delete respective image folder in puzzles/ directory
2. Set status to deleted in DB, remove content in body, manifest_hash and images
3. Update root index.json

TODOs

• Set up manifest DB namespace and replace images namespace
• Implement create manifest workflow
• Implement update manifest workflow
• Implement delete manifest workflow
