# value

The value of a [QuantitativeValue](https://schema.org.ai/QuantitativeValue) (including [Observation](https://schema.org.ai/Observation)) or property value node.

* For [QuantitativeValue](https://schema.org.ai/QuantitativeValue) and [MonetaryAmount](https://schema.org.ai/MonetaryAmount), the recommended type for values is 'Number'.
* For [PropertyValue](https://schema.org.ai/PropertyValue), it can be 'Text', 'Number', 'Boolean', 'StructuredValue' or 'QualitativeValue'.
* Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.
* Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

## Expected Types

| Type | Description |
|------|-------------|
| [Boolean](https://schema.org.ai/Boolean) | Boolean: True or False. |
| [Number](https://schema.org.ai/Number) | Data type: Number. Usage guidelines: Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.; Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator. |
| [QualitativeValue](https://schema.org.ai/QualitativeValue) | A predefined value for a product characteristic, e.g. the power cord plug type 'US' or the garment sizes 'S', 'M', 'L', and 'XL'. |
| [StructuredValue](https://schema.org.ai/StructuredValue) | Structured values are used when the value of a property has a more complex structure than simply being a textual value or a reference to another thing. |
| [Text](https://schema.org.ai/Text) | Data type: Text. |

## Used on Types

| Type | Description |
|------|-------------|
| [MonetaryAmount](https://schema.org.ai/MonetaryAmount) | A monetary value or range. This type can be used to describe an amount of money such as $50 USD, or a range as in describing a bank account being suitable for a balance between £1,000 and £1,000,000 GBP, or the value of a salary, etc. It is recommended to use [PriceSpecification](https://schema.org.ai/PriceSpecification) Types to describe the price of an Offer, Invoice, etc. |
| [PropertyValue](https://schema.org.ai/PropertyValue) | A property-value pair, e.g. representing a feature of a product or place. Use the 'name' property for the name of the property. If there is an additional human-readable version of the value, put that into the 'description' property. Always use specific schema.org properties when a) they exist and b) you can populate them. Using PropertyValue as a substitute will typically not trigger the same effect as using the original, specific property. |
| [QuantitativeValue](https://schema.org.ai/QuantitativeValue) | A point value or interval for product characteristics and other purposes. |
