## Core Concepts

### International Data Spaces (IDS)

IDS represents "a uniform standard for data sharing that can be applied in any professional and private areas" based on European Privacy Policy principles.

### Data Space

A data space is "a virtual place that enables sovereign data governance, based on interoperable standardized components, among involved persons and companies."

Data spaces typically organize around:
- Industries (automotive, manufacturing)
- Topics (sustainability, supply chain)
- Regions (European data spaces)

### Participants

| Role | Description |
|------|-------------|
| Provider | Offers data assets |
| Consumer | Requests data assets |
| Broker | Facilitates discovery (optional) |
| Clearing House | Logs transactions (optional) |

## Contract Negotiation

### Negotiation Process

```
1. Provider creates Asset + Policy → Contract Definition
                    ↓
2. Contract Offers generated from definitions
                    ↓
3. Consumer discovers offers in catalog
                    ↓
4. Consumer initiates negotiation
                    ↓
5. Negotiation iterations (accept/counter/reject)
                    ↓
6. Agreement finalized → Contract established
```

### Contract Components

| Component | Description |
|-----------|-------------|
| Asset | Data being shared |
| Policy | Access rules and constraints |
| Offer | Provider's terms |
| Agreement | Final accepted terms |

### Policy Types

| Policy | Description |
|--------|-------------|
| Access Policy | Who can access |
| Usage Policy | How data can be used |
| Contract Policy | Terms of agreement |

### Policy Examples

```json
{
  "policy": {
    "permissions": [
      {
        "action": "USE",
        "constraints": [
          {
            "leftOperand": "PURPOSE",
            "operator": "EQ",
            "rightOperand": "ANALYTICS"
          }
        ]
      }
    ]
  }
}
```

   │──── Transfer Request ──▶│
   │                         │
   │◀─── EDR (Endpoint) ─────│
   │                         │
   │──── GET /data ─────────▶│
   │     (with EDR token)    │
