Our data in a nutshell

The Rijksmuseum makes available extensive descriptions of more than a half a million art historical objects, hundreds of thousands of object photographs and the complete library catalogue to developers, researchers and enthusiasts. We strive for the highest data quality. We do this by following standards and best practices in the international cultural heritage sector and research fields, while keeping the unique aspects of the Rijksmuseum collection at the forefront of our endeavour.

So that everyone can use our data services, the Rijksmuseum operates an Open Data policy. The basis for this was laid in 2002 when the Rijksmuseum Research Library made its catalogue available via the web as an open data service. In collaboration with Open Cultuur Data, we released a huge number of photographs of objects from the collection as well as the associated metadata under an open licence (CC-BY) in 2011. Two years later, the Rijksmuseum placed the majority of its digitised museum objects in the public domain. We also launched the first API for collection data in 2013.

The Rijksmuseum develops its data services for optimum findability, accessibility, interoperability and reusability of the data. We stick to the FAIR Guiding Principles for Scientific Data Management and Stewardship.

• 130,000 concepts for people and institutions
• 40,000 thesaurus terms

Object metadata

From masterpieces to model ships, you’ll find it in the Rijksmuseum’s collections data. We have now made the details for more than half a million objects available for reuse – most of them with a high resolution image. The Rijksmuseum offers multiple access points for this dataset: via two APIs and also as a download. The dataset is modelled in Dublin Core, the Europeana Data Model and in the LIDO standard. We describe the different methods of accessing our object metadata on data.rijksmuseum.org. To use the APIs, you will need an API key, available from your Rijksstudio account. The use of our APIs is subject to terms and conditions of use.

Bibliographic data

The Rijksmuseum Research Library manages one of the foremost collections of art historical books and journals, as well as auction, exhibition and collections catalogues. We make all of this bibliographic data available as an open data service – including metadata relating to digital publications and electronic magazines – alongside sustainable references to the associated digital files. This data is accessible via two exchange protocols and in different formats. Find out how to use the data on data.rijksmuseum.nl.

Vocabularies

The Rijksmuseum uses controlled vocabularies in order to describe its collection and bibliographic datasets unambiguously. These thesauri contain information about, for example, people, locations, events and concepts. Several of our vocabularies can be downloaded. A dataset of Persons and Institutions containing basic information about 125,000 actors is formatted in the Europeana Data Model. The Rijksmuseum Thesaurus, formatted in SKOS, describes more than 40,000 locations, events and concepts.

Documentation and Archive

Extensive collections documentation, together with the institutional archive, form the Rijksmuseum’s collective memory. In 2019, the museum began digitising these rich data sources. We aim to offer our digitised documentation collection and archive files as a data service in the coming years. To consult these resources, please refer to our Research Library.

Research data

Rijksmuseum researchers, conservators and curators produce terabytes of data every year. The Research Services department is currently building a digital infrastructure for sustainable Research Data management, inspired by the FAIR principles. If you have questions about Research Data Management in the Rijksmuseum, please contact Research Services via the contact form.

Linked Open Data

The Rijksmuseum is currently developing technologies to enable users to make optimal use of Linked Open Data. Several of the datasets we currently offer are already compatible with the semantic web, and all of our collections objects are provided with persistent identifiers. On top of this, we are currently working the implementation of Linked Art.
