<alert type="info">

**Masterdata that travels with events** — `masterDataAvailableFor` is GS1 Web Vocabulary (so no `gs1:` prefix needed — it maps via `@context`). It can carry **lot- or serial-level masterdata** that belongs to a specific instance or batch: production batch, declaration references, incident records, regulatory citations. What it must **not** carry is **GTIN-level masterdata** (product name, generic specifications, basic technical attributes that apply to every unit of that GTIN) — those live on the resolver, POSTed once via `POST /products/{gtin}`. Extension vocabularies (`battery:`, `eudr:`, `textile:`, `electronics:`) must keep their prefix; they are declared in the document's `@context`.

</alert>

<alert type="info">

**Disclaimer**: This is **not official GS1 guidance**, but all event patterns follow official GS1/EPCIS standards:

- [EPCIS 2.0](https://ref.gs1.org/standards/epcis/) — ObjectEvent structure, sensorElementList
- [CBV 2.0](https://ref.gs1.org/standards/cbv/) — bizStep (`commissioning`, `inspecting`), disposition (`active`, `damaged`)
- [UN/CEFACT Rec 20](https://unece.org/trade/uncefact/cl-recommendations) — Unit codes (`P1`, `KWH`, `CEL`)

We follow GS1 best practices: events with full provenance (who/what/when/where), sensor metadata, and master data linking. [Feedback welcome](https://github.com/openepcis/openepcis-battery-dpp/issues)!

## Event Types Overview

The Battery DPP uses EPCIS 2.0 events to capture dynamic battery data throughout its lifecycle. Each event type serves a specific purpose in maintaining the complete battery passport.

## Lifecycle Events

### Commissioning Event

**Purpose**: Record battery creation and initial measurements

<table>
<thead>
  <tr>
    <th>
      Field
    </th>
    
    <th>
      Value
    </th>
  </tr>
</thead>

<tbody>
  <tr>
    <td>
      <code>
        @type

    </td>
    
    <td>

        ObjectEvent

    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        action
      </code>
    </td>
    
    <td>
      <code>
        ADD
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        bizStep
      </code>
    </td>
    
    <td>
      <code>
        commissioning
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        disposition
      </code>
    </td>
    
    <td>
      <code>
        active
      </code>
    </td>
  </tr>
</tbody>
</table>

**Required Sensor Reports**:

- `battery:stateOfHealth` (100%)
- `battery:cycleCount` (0)
- `battery:stateOfCharge`

**Example**:

```json
{
  "@context": "https://ref.gs1.org/standards/epcis/epcis-context.jsonld",
  "type": "ObjectEvent",
  "action": "ADD",
  "bizStep": "commissioning",
  "disposition": "active",
  "epcList": [
    "https://id.gs1.org/01/09521234000013/21/BAT2024-001"
  ],
  "sensorElementList": [
    {
      "sensorReport": [
        {
          "type": "battery:stateOfHealth",
          "value": 100,
          "uom": "P1"
        },
        {
          "type": "battery:cycleCount",
          "value": 0
        }
      ]
    }
  ],
  "masterDataAvailableFor": [
    {
      "id": "https://id.gs1.org/01/09521234000013/21/BAT2024-001",
      "lotNumber": "BATCH-2024-03-A"
    }
  ]
}
```

GTIN-level fields (`productName`, generic specs, `batteryCategory`) live on the resolver. The batch identifier is lot-level, so it travels with the event in `masterDataAvailableFor`.

### Ownership Transfer Event

**Purpose**: Record change of ownership or possession

<table>
<thead>
  <tr>
    <th>
      Field
    </th>
    
    <th>
      Value
    </th>
  </tr>
</thead>

<tbody>
  <tr>
    <td>

        ObjectEvent
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        action
      </code>
    </td>

      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        bizStep
      </code>
    </td>
    
    <td>
      <code>
        accepting
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        disposition
      </code>
    </td>
    
    <td>
      <code>
        in_transit
      </code>
    </td>
  </tr>
</tbody>
</table>

**Required Fields**:

- `sourceList` with `owning_party`
- `destinationList` with `owning_party`
- `bizTransactionList` (PO, invoice)

**Example**:

```json
{
  "@context": "https://ref.gs1.org/standards/epcis/epcis-context.jsonld",
  "@type": "ObjectEvent",
  "action": "OBSERVE",
  "bizStep": "accepting",
  "disposition": "in_transit",
  "sourceList": [
    {
      "type": "owning_party",
      "source": "https://id.gs1.org/417/9521234000006"
    }
  ],
  "destinationList": [
    {
      "type": "owning_party",
      "destination": "https://id.gs1.org/417/9521987000001"
    }
  ],
  "bizTransactionList": [
    {
      "type": "po",
      "bizTransaction": "https://buyer.example.com/orders/PO-2024-0089"
    }
  ]
}
```

### Regulatory Notification Event

**Purpose**: Record regulatory compliance status

<table>
<thead>
  <tr>
    <th>
      Field
    </th>
    
    <th>
      Value
    </th>
  </tr>
</thead>

<tbody>
  <tr>
    <td>
      <code>
        @type
      </code>
    </td>
    
    <td>
      <code>
        ObjectEvent
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        action
      </code>
    </td>
    
    <td>
      <code>
        OBSERVE
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        bizStep
      </code>
    </td>
    
    <td>
      <code>
        notifying
      </code>
    </td>
  </tr>
  
  <tr>
    <td>
      <code>
        disposition
      </code>
    </td>
    
    <td>
      <code>
        conformant
      </code>
    </td>
  </tr>
</tbody>
</table>

**Example**:

```json
{
  "@context": "https://ref.gs1.org/standards/epcis/epcis-context.jsonld",
  "type": "ObjectEvent",
  "action": "OBSERVE",
  "bizStep": "notifying",
  "disposition": "conformant",
  "persistentDisposition": {
    "set": [
      "conformant"
    ]
  },
  "epcList": [
    "https://id.gs1.org/01/09521234000013/21/BAT2024-001"
  ],
  "masterDataAvailableFor": [
    {
      "id": "https://id.gs1.org/01/09521234000013/21/BAT2024-001",
      "regulatoryInformation": [
        {
          "regulationType": "BATTERY_DIRECTIVE",
          "regulatoryAct": "EU 2023/1542",
          "regulatoryIdentifierType": "EU_DECLARATION_OF_CONFORMITY",
          "regulatoryReferenceNumber": "DoC-BAT-2024-00123"
        }
      ]
    }
  ]
}
```

`regulatoryInformation` is GS1 Web Vocabulary (so no `gs1:` prefix), and the declaration is serial-specific — it identifies this unit's Declaration of Conformity. It travels with the event inside `masterDataAvailableFor`. Compliance state is captured as `persistentDisposition: "conformant"` on the event itself.

## Measurement Events

## Adverse Events

**Sensor Report Properties**:

- `battery:incidentSeverity` - Type of incident (transport_damage, fire, etc.)
- `battery:eventDate` - When the incident occurred

**Per-incident masterdata** (in `masterDataAvailableFor`):

- `battery:incidentId` — unique ID for this incident
- `battery:incidentSeverity` — Minor, Moderate, Major, Critical
- `battery:inspectorId` — GLN/GIAI of the inspector
- `battery:recommendedAction` — what to do next

**Example**:

**Sensor Types**:

- `battery:maximumTemperature` — high temperature exposure
- `battery:minimumTemperature` — low temperature exposure
- `Temperature` — actual temperature reading (GS1 Web Vocabulary, unprefixed)

**Additional Properties**:

- `battery:exposureDurationMinutes`
- `battery:exceedanceThreshold`
- `minValue`, `maxValue`, `meanValue`, `sDev`

**Per-excursion masterdata** (in `masterDataAvailableFor`):

- `battery:temperatureExcursionId` — unique ID for this excursion
- `battery:exposureEndTime` — duration of the excursion
- `battery:transportConditions` — context (carrier, route, etc.)
- `battery:estimatedImpact` — assessor's note on consequence
