Schema.org

The catalogue implements a Schema.org metadata profile for all public records. Schema.org is a structured data format developed by Bing, Google, and Yahoo to make web content machine-readable. The catalogue uses it so that Google Dataset Search and POLDER Federated Search can efficiently crawl and index its records. It is also used by the Oceanum Datamesh.

The following fields are carried in each record’s Schema.org profile:

Field	Description
name	Record title
datePublished	Publication date
description	Abstract
identifier	DOI
keywords	Subject keywords
creator	Data creator(s)
publisher	Publishing organisation
distribution	DataDownload for data files; DataLink (custom field) for resource links
