# DataCatalog ## **EARLY RELEASE NOTICE** This class represents a draft that is designed to inform the OpenActive specification work with implementation feedback. It is mostly stable, as it based entirely on schema.org. HOWEVER, IT IS STILL SUBJECT TO CHANGE, as the [Dataset API Discovery specification](https://openactive.io/dataset-api-discovery/EditorsDraft/) evolves. This type is derived from , which means that any of this type's properties within schema.org may also be used. Note however the properties on this page must be used in preference if a relevant property is available. ## **Properties** ### **Required properties** | Property | Expected Type | Description | | --------- | ------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | @type | [`Text`](https://schema.org/Text) | Must always be present and set to `"@type": "DataCatalog"` | | @id | [`URL`](https://schema.org/URL) |

A unique URI-based identifier for the record.

@id properties are used as identifiers for compatibility with JSON-LD. The value of such a property must always be an absolute URI that provides a stable globally unique identifier for the resource, as described in RFC3986.

The primary purpose of the URI format in this context is to provide natural namespacing for the identifier. Hence, the URI itself may not resolve to a valid endpoint, but must use a domain name controlled by the resource owner (the organisation responsible for the OpenActive open data feed).


Example

"@id": ""

| | license | [`URL`](https://schema.org/URL) | Must always be present and set to `"license": "https://creativecommons.org/licenses/by/4.0/"` | | name | [`Text`](https://schema.org/Text) |

The name of the DataCatalog


Example

"name": "Acme Leisure Sessions and Facilities"

| | publisher | [`Organization`](https://developer.openactive.io/data-model/types/organization) |

The organization ultimately responsible for maintaining this DataCatalog.


Example

"publisher": {
"@type": "Organization",
"name": "Central Speedball Association",
"url": ""
}

| ### **Required options** The `DataCatalog` must include either `hasPart` if it is a collection of smaller `DataCatalog`s, or `dataset` if it is a collection of dataset sites. | Property | Expected Type | Description | | -------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | hasPart | Array of [`URL`](https://schema.org/URL) |
