Goals

• Many Archives: Store in many archives at once.
• Emergent Complexity: Small implementation surface with reasonable usage requirements.

Client

Clients gather and send information to archive endpoints.

Commands

• All commands accept --help / -h.
• All commands accept --verbose / -v.
• ev archive register <archive:URL> [user:ID]: Claim a specific User ID on the given archive. User ID is random if omitted.
• ev archive unregister <archive:URL> <user:ID>: Requests the archive to forget this User ID.
• ev archive login <archive:URL> <user:ID> [workspace:PATH]: Sets this combination of Archive URL + User ID as active for this workspace.
• ev archive logout <archive:URL> <user:ID> [workspace:PATH]: Sets this combination of Archive URL + User ID as unactive for this workspace.
• ev save <--note <note:TEXT> | -n <note:TEXT> [workspace:PATH]: Save the workspace's current state as a new Snapshot, with the note when provided.
• ev list [workspace:PATH]: List the Workspace's Snapshots. Also showing notes where set.
• ev clone <source:PATH> <target:PATH> [--snapshot <snapshot:ID> | -s <snapshot:ID>]: Clone the source Workspace to the target path, which may not exist yet. Clone the current workspace state if omitted.
• ev forget {--snapshot <snapshot:ID> | -v <snapshot:ID> | --all | -a} [workspace:PATH]: Forget the specified snapshot(s) for the given Workspace.

Archive

Clients recieve and save information from clients through their URL.

Types

Five distinct types, forming one chain from workspace to content:

Endpoints

• HEAD /type/<type:ID>: Check whether the Type ID already exists.
• GET /type/<type:ID>: Returns an object with the Type's data.
• PUT /type/<type:ID>: Sets the object with the Type's data.
• DELETE /type/<type:ID>: Forget the given Type ID.

Invariants

• All in workspace configuration, will be done under ./ev in the workspace root.
• Archive URL + User ID login configurations are unique per workspace.
