# ObjectOS Implementation Summary
2+
3+
## Overview
4+
5+
Successfully implemented the ObjectOS layer - a new `@objectstack/objectos` package containing system runtime object definitions that represent metadata as queryable data.
6+
7+
## Architecture Decision
8+
9+
Based on architectural discussions, we established:
10+
11+
1. **Location**: `packages/objectos` (NOT `packages/plugins/plugin-system`)
12+
- Rationale: System objects are core infrastructure, not optional plugins
13+
- ObjectOS represents the OS-level primitives of the platform
14+
15+
2. **Dual-Table Pattern**: Keep BOTH systems (do NOT deprecate `sys_metadata`)
16+
- `sys_metadata`: Source of truth for package management, version control, deployment
17+
- Type-specific tables (`sys_object`, `sys_view`, etc.): Queryable data for UI/reporting
18+
19+

## System Objects Implemented
41+
42+
### 1. sys_metadata (Generic Envelope)
43+
- **Purpose**: Source of truth for package management
44+
- **Features**: Version control, checksums, package ownership, deployment tracking
45+
- **Fields**: 20+ fields including version, checksum, package_id, managed_by, scope
46+
47+
### 2. sys_object (Queryable Object Definitions)
48+
- **Purpose**: Browse/filter/search object definitions in Studio
49+
- **Features**: Denormalized data, complex fields as JSON
50+
- **Fields**: 30+ fields including fields_json, capabilities_json, field_count
51+
52+
### 3. sys_view (Queryable View Definitions)
53+
- **Purpose**: Manage view metadata through Object Protocol
54+
- **Features**: View type filtering, object references
55+
- **Fields**: columns_json, filters_json, sort_json, config_json
56+
57+
### 4. sys_agent (AI Agent Definitions)
58+
- **Purpose**: AI agent configuration as data
59+
- **Features**: Model config, tools/skills management
60+
- **Fields**: model, temperature, system_prompt, tools_json, skills_json
61+
62+
### 5. sys_tool (AI Tool Definitions)
63+
- **Purpose**: AI tool registry as queryable data
64+
- **Features**: Parameter schemas, handler code
65+
- **Fields**: parameters_json, handler_code
66+
67+
### 6. sys_flow (Automation Flow Definitions)
68+
- **Purpose**: Flow metadata management
69+
- **Features**: Flow types, trigger configuration
70+
- **Fields**: flow_type, nodes_json, edges_json, trigger_type
71+
72+
## Key Features
73+
74+
1. **Metadata as Data**
75+
- All metadata types are queryable using Object Protocol
76+
- Same CRUD operations as business data
77+
- Consistent API: `/api/v1/data/sys_object`, `/api/v1/data/sys_view`
78+
79+
2. **Dual-Table Architecture**
80+
```
81+
Package Loader
82+
↓
83+
sys_metadata (source of truth)
84+
↓ (projection)
85+
sys_object, sys_view, etc. (queryable)
86+
↓
87+
Studio UI (auto-generated)
88+
```
89+
90+
3. **Version Management**
91+
- `sys_metadata` tracks all versions
92+
- `sys_metadata_history` table for history
93+
- Checksum-based change detection
94+
- Package upgrade/downgrade support
95+
96+
4. **Auto-Generated UI**
97+
- Studio uses Object Protocol
98+
- No custom UI code per metadata type
99+
- Leverage grid/form/kanban views
100+
101+
## Industry Alignment
102+
103+
- **Salesforce**: CustomObject, CustomField (queryable metadata)
104+
- **ServiceNow**: sys_db_object, sys_dictionary (table-based metadata)
105+
- **Kubernetes**: CRDs as structured resources
106+
107+
## Next Steps
108+
109+
### Phase 1: Integration (Immediate)
110+
- [ ] Update `packages/metadata` service to support projection
111+
- [ ] Implement dual-table sync logic
112+
- [ ] Register system objects in runtime bootstrap
113+
114+
### Phase 2: Studio Integration (Next)
115+
- [ ] Update Studio to query type-specific tables
116+
- [ ] Use `/api/v1/data/sys_object` for browsing
117+
- [ ] Auto-generate metadata forms
118+
119+
### Phase 3: Testing & Documentation (Later)
120+
- [ ] Add comprehensive test coverage
121+
- [ ] Update documentation
122+
- [ ] Create migration guides
123+
124+
## Usage Example
125+
126+
```typescript
127+
import { SystemObjects } from '@objectstack/objectos';
128+
129+
// Register all system objects during bootstrap
130+
for (const [name, definition] of Object.entries(SystemObjects)) {
131+
await kernel.metadata.register('object', name, definition, {
132+
scope: 'system',
133+
isSystem: true,
134+
managedBy: 'platform',
135+
});
136+
}
137+
138+
// Query metadata using Object Protocol
139+
const objects = await client.data.find('sys_object', {
140+
filter: { namespace: 'crm' },
141+
sort: 'name',
142+
});
143+
144+
// Studio auto-generates UI
145+
<GridView object="sys_object" />
146+
<FormView object="sys_object" recordId="account" />
147+
```
148+
149+
## Benefits
150+
151+
1. ✅ **Unified Protocol**: One protocol for both data and metadata
152+
2. ✅ **Auto-Generated UI**: Studio reuses existing components
153+
3. ✅ **Better DX**: Consistent API for all entity types
154+
4. ✅ **Version Control**: Full history via sys_metadata_history
155+
5. ✅ **Package Management**: Track ownership and deployments
156+
6. ✅ **Industry Standard**: Follows Salesforce/ServiceNow patterns

174+
## Conclusion
175+
176+
The ObjectOS package establishes a clean architectural foundation for treating metadata as queryable data. This enables auto-generated Studio UI, unified APIs, and follows industry best practices from Salesforce, ServiceNow, and Kubernetes.
177+
178+
The dual-table architecture preserves the benefits of `sys_metadata` for package management while adding queryability through type-specific tables.

**ObjectOS - System Runtime Object Definitions**
4+
5+
This package contains the core system object definitions that form the foundation of the ObjectStack platform. These objects represent the metadata layer itself (objects, views, flows, agents, etc.) as queryable data.
6+
7+
## Architecture
8+
9+
ObjectStack follows a layered architecture:
10+
11+
- **Protocol Layer** (`@objectstack/spec`) — Zod schemas (ObjectSchema, ViewSchema, AgentSchema)
12+
- **Runtime Layer** (`@objectstack/objectos`) — Concrete system objects (SysObject, SysView, SysAgent)
13+
- **Service Layer** (`@objectstack/metadata`) — Metadata management service
14+
15+
## System Objects
16+
17+
ObjectOS provides system object definitions for all metadata types:
18+
19+
### Data Protocol
20+
- `sys_metadata` - Generic metadata envelope
21+
- `sys_object` - Object definitions
22+
- `sys_field` - Field definitions
23+
24+
### UI Protocol
25+
- `sys_view` - View definitions
26+
- `sys_dashboard` - Dashboard definitions
27+
- `sys_app` - App definitions
28+
- `sys_action` - Action definitions
29+
30+
### Automation Protocol
31+
- `sys_flow` - Flow definitions
32+
- `sys_workflow` - Workflow definitions
33+
34+
### AI Protocol
35+
- `sys_agent` - AI Agent definitions
36+
- `sys_tool` - AI Tool definitions
37+
- `sys_skill` - AI Skill definitions
38+
39+
### Security Protocol
40+
- `sys_permission` - Permission sets
41+
- `sys_profile` - User profiles
42+
- `sys_role` - Security roles
43+
44+
### Identity Protocol
45+
- `sys_user` - System users
46+
- `sys_organization` - Organizations
47+
48+
### System Protocol
49+
- `sys_environment` - Environments
50+
- `sys_datasource` - Datasources
51+
- `sys_package` - Installed packages
52+
- `sys_translation` - Translation bundles
53+
54+
## Usage
55+
56+
```typescript
57+
import { SystemObjects } from '@objectstack/objectos';
58+
59+
// Register all system objects
60+
await metadataService.registerSystemObjects(SystemObjects);
61+
62+
// Or register individual objects
63+
import { SysObject } from '@objectstack/objectos/objects';
64+
await metadataService.register('object', 'sys_object', SysObject);
65+
```
66+
67+
## Design Philosophy
68+
69+
ObjectOS follows the "Metadata as Data" pattern:
70+
71+
1. **Dual-Table Architecture**: System metadata is stored in both `sys_metadata` (source of truth) and type-specific tables (queryable data)
72+
2. **Object Protocol**: All system objects use the same Object Protocol as business data
73+
3. **Auto-Generated UI**: Studio can render metadata forms/tables using existing view components
74+
4. **Version Control**: Full version history via `sys_metadata_history` table
75+
5. **Package Management**: Metadata tracked by package ownership
76+
77+
## Industry Alignment
78+
79+
- **Salesforce**: Treats metadata as queryable objects (CustomObject, CustomField)
80+
- **ServiceNow**: System Dictionary is a table, queryable like any other
81+
- **Kubernetes**: CRDs are stored as structured resources
