# Views sheet reference

> Complete reference for views and filters in the NEAT physical data model Excel sheet, including filter syntax and examples.

The Views sheet defines views and their filters in the NEAT physical data model. Each view maps to a logical schema that specifies which nodes or edges to return when querying.

## Filter

Filters specify which nodes or edges should be returned when querying a view. Use a unique container for each view and the default filter set by the API.

The NEAT physical data model maps one-to-one to the CDF API specification for creating data models. Validation is limited to basic syntax checking, so use filters with caution. Write raw JSON strings in the `Filter` column to set a filter.

| View                   | Implements         | Filter                               |
| ---------------------- | ------------------ | ------------------------------------ |
| Cognite360ImageStation | CogniteDescribable | See the JSON example in this section |

Example filter JSON:

```json wrap theme={"languages":{"custom":["/_languages/kuiper.json","../_languages/kuiper.json"]}}
{"and": [{"hasData": [{"type": "container", "space": "cdf_cdm_3d", "externalId": "Cognite3DGroup"}]}, {"equals": {"property": ["cdf_cdm_3d", "Cognite3DGroup", "groupType"], "value": "Station360"}}]}
```

<Warning>
  Ensure the JSON string is properly formed and valid. Invalid JSON causes errors.
</Warning>
