Directory and data management services API and protocol

This page lists all of the functions that we can think of that may be made interoperable. Functional areas can be added, and discussions of how each function applies to different frameworks (lStore, Lodn, ...)

Name service

• Directory manipulation - opendir like interface (create,delete,move,walk)
• Open/close; obtain a handle/ release handle
• get file mappings
• soft links - internal and external
• add arbitrary metadata ala xfs
• registration of a policy - microservices

Data logistics

• Specify lun + upload, download
• replication
• allocate space
• data migration
• object life times
• advanced resource allocation
• workflows
• data-pathing
• quotas

Data integrity

• fault tolerance
• recover failed mappings
• object integrity
• fsck/format/default options

Security

• permissions
• auth/authz
• encryption

Misc

• locking file & byte range (Persistency)
• versioning (?)
• object semantics - versioning/copy-on-write/locking etc (?)
