CoJSON

CoJSON ("Collaborative JSON") will be a minimal protocol and implementation for collaborative values (CRDTs + public-key cryptography).

CoJSON is developed by Garden Computing as the underpinnings of Jazz, a framework for building apps with telepathic data.

The protocol and implementation will cover:

• how to represent collaborative values internally
• the APIs collaborative values expose
• how to sync and query for collaborative values between peers
• how to enforce access rights within collaborative values locally and at sync boundaries

THIS IS WORK IN PROGRESS

Core Value Types

Immutable Values (JSON)

• null

• boolean

• number

• string

  • stringly-encoded CoJSON identifiers & data (CoValueID, AgentID, SessionID, SignatoryID, SignatorySecret, Signature, RecipientID, RecipientSecret, Sealed, Hash, ShortHash, KeySecret, KeyID, Encrypted, Role)

• array

• object

Collaborative Values

• CoMap (string → Immutable, last-writer-wins per key)
  • Team (AgentID → Role)
• CoList (Immutable[], addressable positions, insertAfter semantics)
  • Agent ({signatoryID, recipientID}[])
• MultiStream (independent per-session streams of Immutables)
• Static (single addressable Immutable)

Implementation Abstractions

• MultiLog
  • Session Logs
  • Transactions
    • Private (encrypted) transactions
    • Trusting (unencrypted) transactions
  • Rulesets
• CoValue Types
• LocalNode
  • Peers
  • AgentCredentials
• Peer

Extensions & higher-level protocols

More complex datastructures

• CoText: a clean way to collaboratively mark up rich text with CoJSON
• CoJSON Tree: a clean way to represent collaborative tree structures with CoJSON
