Implementation Status Matrix

This document provides a comprehensive overview of which protocols from @objectstack/spec have been implemented in the ObjectStack packages.

Last Updated: February 2026

This matrix is generated from actual codebase analysis and represents the current implementation status.

Status Legend

Symbol	Status	Description
✅	Fully Implemented	Production-ready implementation with all core features
⚠️	Partially Implemented	Basic implementation, missing advanced features
🚧	In Progress	Currently being developed
📋	Planned	Scheduled for future implementation
❌	Not Implemented	Protocol defined but not yet implemented

Core Infrastructure (ObjectOS)

Runtime & Kernel

Protocol	@objectstack/core	@objectstack/runtime	@objectstack/objectql	Status
Manifest	✅	✅	✅	✅ Full
Context	✅	✅	✅	✅ Full
Plugin	✅	✅	❌	✅ Full
Plugin Lifecycle	✅	❌	❌	✅ Full
Plugin Capability	✅	❌	❌	✅ Full
Service Registry	✅	❌	❌	✅ Full
Startup Orchestrator	✅	❌	❌	✅ Full
Events	✅	❌	❌	✅ Full

Notes:

Core package provides complete microkernel implementation
Plugin system supports lifecycle hooks, dependency resolution, and service injection
Event bus enables inter-plugin communication
ObjectQL serves as the example kernel — a reference implementation that will be modularized into plugins

Data Infrastructure

Protocol	@objectstack/objectql	@objectstack/runtime	@objectstack/driver-memory	Status
Driver	✅	✅	⚠️	✅ Interface
Datasource	✅	✅	❌	✅ Full
Data Engine	✅	❌	❌	✅ Full
Query	✅	⚠️	⚠️	⚠️ Partial
Filter	✅	⚠️	⚠️	⚠️ Partial

Notes:

ObjectQL implements complete IDataEngine interface
Memory driver is reference implementation (basic CRUD only)
Advanced query features (aggregations, window functions) require production drivers
Memory driver supports aggregations (groupBy, count, sum, avg, min, max)

Metadata Framework

Degraded Status — Metadata is an in-memory registry framework. Database persistence for metadata storage is not yet implemented. Discovery reports this service as degraded.

Metadata API (list types, list items, get item) is fully functional
Metadata is loaded from config files at startup and held in memory
Future: metadata persistence to database for runtime modifications

Memory driver supports basic queries only
Client SDK provides query builder utilities

API Layer (Transport)

`/meta/{type}`	GET	List items of type	✅
`/meta/{type}/{name}`	GET	Get specific metadata item	✅

UI Layer (ObjectUI)

View System

Protocol	@objectstack/spec	Implementation	Status
View	✅	❌	❌ Spec only
ListView	✅	❌	❌ Spec only
FormView	✅	❌	❌ Spec only
Page	✅	❌	❌ Spec only
App	✅	❌	❌ Spec only
Dashboard	✅	❌	❌ Spec only
Report	✅	❌	❌ Spec only
Action	✅	❌	❌ Spec only
Component	✅	❌	❌ Spec only
Theme	✅	❌	❌ Spec only
Widget	✅	❌	❌ Spec only
Chart	✅	❌	❌ Spec only

Notes:

All UI protocols are fully defined in spec
Metadata API can retrieve UI definitions (views, apps)
No built-in UI renderer yet - designed for custom implementations
React SDK provides data hooks, UI rendering is application responsibility

Automation Layer

Plugin-Provided Service — The kernel does NOT include an automation engine. Flow, workflow, and approval services must be provided by plugins (e.g., @objectstack/plugin-automation).

Protocol	@objectstack/spec	Kernel	Plugin Required	Status
Flow	✅	❌	✅	📋 Plugin
Workflow	✅	❌	✅	📋 Plugin
Approval	✅	❌	✅	📋 Plugin
Webhook	✅	❌	✅	📋 Plugin
ETL	✅	❌	✅	📋 Plugin
Sync	✅	❌	✅	📋 Plugin
Trigger Registry	✅	❌	✅	📋 Plugin

Notes:

Hook system is implemented in ObjectQL (beforeFind, afterInsert, etc.) — this is data-layer eventing, not workflow automation
Full workflow/automation engine will be provided by plugins
Protocols are complete and ready for plugin implementation
Discovery API reports automation service as unavailable until a plugin is registered

Plugin-Provided Service — The kernel does NOT handle authentication or authorization. Security services must be provided by plugins (e.g., @objectstack/plugin-auth). The Discovery API reports auth as unavailable until a plugin is registered.

Auth Service (`plugin-auth`)

The auth service in CoreServiceName covers both authentication (identity) and authorization (permissions). There is no separate permission service — it is part of auth.

Protocol	Area	@objectstack/spec	Kernel	Plugin Required	Status
Identity	Authentication	✅	❌	✅	📋 Plugin
Auth Config	Authentication	✅	❌	✅	📋 Plugin
Role	Authentication	✅	❌	✅	📋 Plugin
Organization	Authentication	✅	❌	✅	📋 Plugin
Policy	Authentication	✅	❌	✅	📋 Plugin
SCIM	Authentication	✅	❌	✅	📋 Plugin
Permission	Authorization	✅	❌	✅	📋 Plugin
Sharing	Authorization	✅	❌	✅	📋 Plugin
RLS	Authorization	✅	❌	✅	📋 Plugin
Territory	Authorization	✅	❌	✅	📋 Plugin

Notes:

All security protocols (identity + permission) are delivered by a single auth plugin — matching CoreServiceName
Client SDK supports bearer token header — but token validation requires the auth plugin
Auth route (/auth/*) only appears in Discovery when the auth plugin is registered
Fine-grained authorization (RLS, sharing, territory) is internal to the auth plugin
