# Schemas

> Create and manage reusable schemas that define what data to extract

Schemas define the structure of data you want to extract from websites. They specify field names, data types, and descriptions. Schemas can be reused across multiple workflows.

For example, if you need to extract store locations from 5 different websites, you can create one schema and use it for all of them.

## Managing Schemas

Schemas can be created and managed in two ways:

<CardGroup cols={2}>
  <Card title="In the UI" icon="window" href="/docs/ui/workflows/schemas">
    Create schemas visually using the schema builder, or select from existing templates.
  </Card>

  <Card title="Via Code" icon="code" href="/docs/sdk/schemas/overview">
    Create and manage schemas programmatically with full control over field definitions.
  </Card>
</CardGroup>

## Data Types

When defining schemas, you specify the data type for each field to ensure accurate extraction and validation. Kadoa supports the following data types:

| Data Type    | Description                         | Example Use Cases                                     |
| ------------ | ----------------------------------- | ----------------------------------------------------- |
| **STRING**   | String/text content                 | Product names, descriptions, article headlines        |
| **NUMBER**   | Numeric values (integers, decimals) | Quantities, ratings, scores, counts                   |
| **BOOLEAN**  | True/false values                   | Availability status, feature flags, yes/no indicators |
| **DATE**     | Date values                         | Publication dates, deadlines, event dates             |
| **DATETIME** | Date and time values                | Timestamps, scheduled times, last updated             |
| **MONEY**    | Currency and monetary values        | Prices, costs, revenue, discounts                     |
| **IMAGE**    | Image URLs and references           | Product photos, thumbnails, profile pictures          |
| **LINK**     | URLs and hyperlinks                 | Product pages, external links, social media           |
| **OBJECT**   | Nested/complex JSON structures      | Structured metadata, complex configurations           |
| **ARRAY**    | Lists/arrays of values              | Tags, categories, multiple images, feature lists      |

Choose the appropriate data type to ensure your data is extracted and validated correctly.

### Data Type Formats

Some data types return structured values:

| Data Type | Format                                       | Example                                                |
| --------- | -------------------------------------------- | ------------------------------------------------------ |
| **MONEY** | `{"amount": number, "currencyCode": string}` | `$124.50` → `{"amount": 12450, "currencyCode": "USD"}` |

<Note>
  The `amount` field is always in the smallest currency unit (e.g., cents for USD, pence for GBP).
</Note>

## Special Field Types

Beyond regular data fields, Kadoa supports special field types for advanced use cases:

### Classification Fields

Automatically categorize content into predefined labels. Useful for:

* Sentiment analysis (Positive/Negative/Neutral)
* Content categorization (Technology/Business/Sports)
* Priority classification (High/Medium/Low)

[Learn more about classification in the SDK →](/docs/sdk/schemas/overview#classification-fields)

### Metadata Fields (Raw Content)

Extract raw page content in different formats:

* **HTML** - Raw HTML source code
* **MARKDOWN** - Markdown formatted content
* **PAGE\_URL** - Page URL

## Templates

Schemas can be bundled into [templates](/docs/templates) along with a prompt and notification settings. Templates let you apply the same configuration to multiple workflows and manage it in one place.
