Originally, URLs from [GoodRelations](http://purl.org/goodrelations/v1) were used (for [Monday](https://schema.org.ai/Monday), [Tuesday](https://schema.org.ai/Tuesday), [Wednesday](https://schema.org.ai/Wednesday), [Thursday](https://schema.org.ai/Thursday), [Friday](https://schema.org.ai/Friday), [Saturday](https://schema.org.ai/Saturday), [Sunday](https://schema.org.ai/Sunday) plus a special entry for [PublicHolidays](https://schema.org.ai/PublicHolidays)); these have now been integrated directly into schema.org. **Extends:** [Enumeration](https://schema.org.ai/Enumeration) ## [Enumeration](https://schema.org.ai/Enumeration) Properties | Property | Expected Type | Description | |----------|---------------|-------------| | [supersededBy](https://schema.org.ai/supersededBy) | [Class](https://schema.org.ai/Class), [Enumeration](https://schema.org.ai/Enumeration), [Property](https://schema.org.ai/Property) | Relates a term (i.e. a property, class or enumeration) to one that supersedes it. | ## [Thing](https://schema.org.ai/Thing) Properties | Property | Expected Type | Description | |----------|---------------|-------------| | [additionalType](https://schema.org.ai/additionalType) | [Text](https://schema.org.ai/Text), [URL](https://schema.org.ai/URL) | An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org [style guide](https://schema.org/docs/styleguide.html). | | [alternateName](https://schema.org.ai/alternateName) | [Text](https://schema.org.ai/Text) | An alias for the item. | | [description](https://schema.org.ai/description) | [Text](https://schema.org.ai/Text), [TextObject](https://schema.org.ai/TextObject) | A description of the item. | | [digital](https://schema.org.ai/digital) | [Number](https://schema.org.ai/Number) | Digital maturity score from 0.0 (fully analog/manual) to 1.0 (fully digital/autonomous).

A short description of the item used to disambiguate from other, similar items.

See [background notes](https://schema.org/docs/datamodel.html#identifierBg) for more details. | | [image](https://schema.org.ai/image) | [ImageObject](https://schema.org.ai/ImageObject), [URL](https://schema.org.ai/URL) | An image of the item.

E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website. | | [subjectOf](https://schema.org.ai/subjectOf) | [CreativeWork](https://schema.org.ai/CreativeWork), [Event](https://schema.org.ai/Event) | A CreativeWork or Event about this Thing. | | [url](https://schema.org.ai/url) | [URL](https://schema.org.ai/URL) | URL of the item. | ## Values | Value | Description | |-------|-------------| | [Friday](https://schema.org.ai/Friday) | The day of the week between Thursday and Saturday. | | [Monday](https://schema.org.ai/Monday) | The day of the week between Sunday and Tuesday. | | [PublicHolidays](https://schema.org.ai/PublicHolidays) | This stands for any day that is a public holiday; it is a placeholder for all official public holidays in some particular location.
