Storage API

This is the discussion page for the Archivematica Storage API (Issue #5158), requirements, and proposed implementations.

Initial Research

Goal: Look at all the places Archivematica currently accesses the filesystem, and categorize them.

Categories:

• Transfers
• Quarantine
• Backlog transfer
• Currently Processing
  • Anything initiated by putting files in a watchedDirectory, anything being processed by a MicroServiceChain
  • touched everywhere, in all the client scripts, with python and client scripts.
  • Probably best to keep local
  • Already set up to be move-able with %sharedDirectory% as long as folder structure inside %sharedDirectory% is preserved
• AIP Storage
  • done in one place: src/MCPClient/lib/clientScripts/storeAIP.py

Ways Archivematica can touch the filesystem:

• python's open()
• python's shutil.{move|copy|rm}
• python's os module (checking if file/directory exists, create directory, remove file)
• cp, mv, mkdir, rm, chmod as client Scripts
• dashboard configs (eg. AIP storage location, transfer source)
  • dashboard.components.main.models.py SourceDirectory, StorageDirectory
