# categorical-row

The *categorical-row* **parser** will load data from one or more rows from a source data table into categorical **variables** within **collections**.

It inherits attributes and data loading behaviors from the abstract *row* **parser** type.

## Attribute - indicator

The *indicator* attribute is optional. It specifies a value which will indicate that an entity should be included in the generated **variable** for that row.

```
{
  "parser_type": "categorical-row",
  "collection": "collection_name",
  "variable": {...},
  
  "indicator": "1"
}
```

## Attribute - map

The *map* attribute is optional. It can be used as an alternative to using the *variable* attribute. **Variable** names will be created from the values within each row.

```
{
  "parser_type": "categorical-row",
  "collection": "collection_name",
  
  "map": {
    "1": "XXXX",
    "0": "YYYY",
  }
}
```

## Attribute - value

The *value* attribute is optional. It can be used as an alternative to using the *variable* attribute. It specifies a constant value which will become the **variable** name.

```
{
  "parser_type": "categorical-row",
  "collection": "collection_name",
  
  "value": "Is in dataset"
}
```
