# ODMDB Natural Language Query PoC

This is a **Proof of Concept (PoC)** that demonstrates the conversion of natural language queries into ODMDB search queries using OpenAI's structured output API.

## Current Status

✅ **Complete Multi-Schema Implementation**: Supports **all ODMDB object types** including seekers, jobads, recruiters, persons, and sirets. The system intelligently detects the target object from natural language queries and generates appropriate ODMDB DSL queries.

## Features

- **Multi-Object Natural Language Processing**: Intelligently detects target object (seekers, jobads, recruiters, persons, sirets) from natural language queries
- **Real ODMDB Schema Integration**: Dynamically loads actual schema files for all object types with verified accuracy
- **Comprehensive Field Mapping**: Uses real schema definitions with proper access rights for recruiter-readable fields
- **Index-Aware Query Generation**: Leverages actual ODMDB indexes for optimal query performance
- **Schema Mapping Manager**: Centralized system reading real schema files and generating comprehensive field synonyms
- **Multi-Object Query Support**: Handles queries across all ODMDB object types with object-specific optimizations
- **OpenAI Structured Output**: Dynamic JSON schema generation for any target object type
- **Real Data Validation**: Verified against actual ODMDB schema properties and index registers
- **Prepared Query Demos**: Ready-to-use example queries for all supported object types

## Prerequisites

- Node.js (v16 or higher)
- OpenAI API key

## Installation

1. Make sure you have the complete ODMDB data structure available:

   ```
   ../smatchitObjectOdmdb/
   ├── schema/
   │   ├── seekers.json       # Seeker schema (62 properties, 27 readable fields)
   │   ├── jobads.json        # Job advertisement schema
   │   ├── recruiters.json    # Recruiter schema
   │   ├── persons.json       # Person schema
   │   ├── sirets.json        # Company/Siret schema
   │   └── *.json            # Additional schema files
   └── objects/
       ├── seekers/
       │   ├── idx/          # Index files (lst_alias, seekstatus_alias, etc.)
       │   └── itm/          # Individual seeker JSON files
       ├── jobads/
       │   ├── idx/          # Job ad indexes
       │   └── itm/          # Job ad data files
       ├── recruiters/
       │   ├── idx/          # Recruiter indexes
       │   └── itm/          # Recruiter data files
       ├── persons/
       │   └── itm/          # Person data files
       └── sirets/
           └── itm/          # Company data files
   ```

2. Install dependencies:

   ```bash
   npm install
   ```

3. Set your OpenAI API key:
   ```bash
   export OPENAI_API_KEY=sk-your-api-key-here
   ```

## Usage

### Running the PoC

**Interactive Demo (Recommended):**

```bash
node demo.js
```

This runs the comprehensive demo with prepared queries for all object types and shows real-time query generation.

**Main PoC (Query Generation Only):**

```bash
npm start
```

**Main PoC with Query Execution:**

```bash
EXECUTE_QUERY=true npm start
```

This will process the hardcoded natural language query and output the generated ODMDB query in JSON format. When `EXECUTE_QUERY=true`, it will also execute the query against the ODMDB server.

### Changing the Query

To test different natural language queries, edit the `NL_QUERY` constant in `poc.js`:

```javascript
// Line 16 in poc.js
const NL_QUERY = "your natural language query here";
```

The system will automatically detect which object type you're asking about and generate the appropriate query.

### Example Queries by Object Type

#### Seekers (Job Seekers)

**Status-based queries:**

- `"show me seekers with status startasap and their email and experience"`
- `"find seekers looking for jobs urgently with their skills and salary expectations"`
- `"get seekers who are not looking with their employment status"`

**Skills & experience:**

- `"find seekers with technical skills and years of experience"`
- `"show me seekers with language abilities and personality profiles"`
- `"get seekers with specific know-how and job radar interests"`

**Location & preferences:**

- `"show me seekers in Paris with remote work preferences"`
- `"find seekers available to work in multiple countries"`
- `"get seekers with specific location and salary requirements"`

#### Job Ads

**Job search queries:**

- `"show me recent job postings in technology"`
- `"find job ads with high salary ranges"`
- `"get job advertisements posted this week"`

**Company & location:**

- `"show me jobs at specific companies"`
- `"find remote job opportunities"`
- `"get job ads in Paris or Lyon"`

#### Recruiters

**Recruiter information:**

- `"show me active recruiters and their specializations"`
- `"find recruiters from specific companies"`
- `"get recruiter contact information and experience"`

#### Persons

**General person queries:**

- `"show me person profiles with their roles"`
- `"find persons by their experience or background"`

#### Companies (Sirets)

**Company information:**

- `"show me companies in the technology sector"`
- `"find companies by size or location"`
- `"get company details and contact information"`

### Supported Query Types

**Multi-Object Intelligence:**
The system automatically detects which object you're asking about:

- Mentions of "seekers", "candidates", "job seekers" → seekers object
- Mentions of "jobs", "positions", "job ads" → jobads object
- Mentions of "recruiters", "hiring managers" → recruiters object
- Mentions of "persons", "people", "profiles" → persons object
- Mentions of "companies", "employers", "organizations" → sirets object

**Filter Types:**

- **Status filtering**: Object-specific status fields
- **Date filtering**: Creation dates, update dates with date ranges
- **Index optimization**: Uses real ODMDB indexes for efficient queries
- **Field-specific**: Searches within specific properties

## Schema Mapping System

The PoC uses a sophisticated schema mapping system located in `schema-mappings/`:

### Architecture

- **ODMDBMappingManager**: Central manager that loads and caches schema mappings
- **Base Mapping**: Core field synonym generation and mapping logic
- **Object-Specific Mappings**: Individual mapping files for each object type
- **Real Schema Integration**: Direct reading from actual ODMDB schema files

### Verified Schema Coverage

**Seekers Object:**

- 62 total schema properties mapped
- 27 recruiter-readable fields identified
- 3 indexes available (lst_alias, seekstatus_alias, alias)
- 206+ field synonyms generated from real schema definitions

**All Objects:**

- Dynamic schema loading for any ODMDB object type
- Access rights properly extracted from apxaccessrights structure
- Index definitions read from actual idx directories
- Field synonyms generated from real property definitions

### Field Mapping Examples

The system provides comprehensive natural language to field mappings:

**Contact & Identity:**

- `email`, `contact`, `mail` → `email`
- `id`, `username`, `alias` → `alias`
- `bio`, `description`, `summary` → `shortdescription`

**Work Experience & Status:**

- `experience`, `years of experience`, `career length` → `seekworkingyear`
- `job titles`, `positions`, `roles`, `work history` → `seekjobtitleexperience`
- `status`, `availability`, `urgency` → `seekstatus`

**Location & Geography:**

- `location`, `where`, `work location` → `seeklocation`
- `countries`, `work countries` → `countryavailabletowork`

**Skills & Competencies:**

- `skills`, `competencies`, `abilities` → `skills`
- `languages`, `language skills` → `languageskills`
- `knowledge`, `expertise`, `know-how` → `knowhow`

_(Plus hundreds more mappings for all object types)_

## Output Format

The PoC generates ODMDB queries in this format:

```json
{
  "object": "seekers",
  "condition": ["prop.dt_create(>=:2025-10-06)"],
  "fields": ["alias", "email", "seekworkingyear"]
}
```

## ODMDB DSL Support

The PoC understands and generates these ODMDB DSL patterns:

- **Property queries**: `prop.<field>(operator:value)`
- **Index queries**: `idx.<indexName>(value)`
- **Join queries**: `join(remoteObject:localKey:remoteProp:operator:value)`

## Demo & Testing Tools

**Interactive Demo:**

```bash
node demo.js
```

**Live PoC demonstration** featuring:

- Real query generation from natural language using OpenAI
- Multi-object detection and schema loading
- Prepared queries for all supported object types
- Real-time field mapping and validation
- Current ODMDB data status display

**Demo Features:**

- **Prepared Queries**: 4 example queries per object type (20 total)
- **Schema Validation**: Shows actual field counts and mappings
- **Real-time Generation**: Demonstrates actual OpenAI API integration
- **Multi-Object Support**: Covers seekers, jobads, recruiters, persons, sirets

## Environment Variables

- `OPENAI_API_KEY` - Your OpenAI API key (required)

## System Validation

The mappings have been thoroughly validated to ensure they:

✅ **Read actual ODMDB schema files** - Not hardcoded mappings  
✅ **Access real index registers** - Uses actual idx directory files  
✅ **Extract proper access rights** - Reads apxaccessrights.recruiters.R structure  
✅ **Generate comprehensive synonyms** - 200+ field mappings per object  
✅ **Support all object types** - Dynamic loading for any ODMDB schema

## Technical Architecture

### Core Components

1. **poc.js**: Main PoC engine with multi-object support
2. **demo.js**: Comprehensive demonstration with prepared queries
3. **schema-mappings/**: Real schema integration system
4. **package.json**: Dependencies and execution scripts

### Schema Integration Flow

1. **Schema Loading**: ODMDBMappingManager reads actual schema files
2. **Field Extraction**: Extracts properties and access rights from real schemas
3. **Index Integration**: Reads index definitions from idx directories
4. **Synonym Generation**: Creates comprehensive field mappings
5. **Query Generation**: Uses OpenAI with dynamic schema for target object
6. **Validation**: Ensures generated queries match schema constraints

### Data Flow

```
