The Record API provides direct access to Europeana’s data and metadata, which is modelled using /wiki/spaces/EF/pages/2385313809. EDM is an open flexible data model used to capture the data and metadata about Cultural Heritage Objects (CHOs). The Record API is used to retrieve all of the data and metadata that relates to a single Cultural Heritage object, which will have a single Europeana ID. A Europeana ID is made up of a dataset number, and a record ID. For the object at this URL: https://www.europeana.eu/item/90402/RP_P_1984_87, the dataset ID is 90402, and the record ID is RP_P_1984_87. Both are findable by looking at the URL.
Before starting to use this API, we recommend reading the introduction page for an overview of the /wiki/spaces/EF/pages/2385313809, Registering for an API key, and reading the Terms of Use. If you want to get started with this API, go directly to the Getting Started section or try it out directly on the Console.

Getting Started
Every call to the Record API is an HTTPS request in the following URL signature:
https://api.europeana.eu/record/v2/[RECORD_ID].[FORMAT]
Where the variables in the URL path mean:
RECORD_ID | The identifier of the record which is composed of the dataset identifier plus a local identifier within the dataset in the form of "/DATASET_ID/LOCAL_ID", for more detail see Europeana ID. |
FORMAT | The file extension corresponding to one of the supported output formats, namely: .json, .jsonld, .rdf. See next section on Output Formats |
Additional parameters may apply to the request above such as the API key and Browser access.
An example Record API call to get all of the data and metadata from this item in JSON would be: https://api.europeana.eu/record/v2/90402/RP_P_1984_87.json?wskey=YOURAPIKEY
The Record API supports 3 serialization formats, namely: JSON, JSON-LD and RDF/XML. The primary and default output supported by this API is JSON which also means that some fields are only available in this format. Both JSON-LD and RDF/XML are formats to represent Linked Data which used predefined transport schemas for serializing RDF data. To request a record in either of these formats, just alter the extension of the call to the desired format. The table below explains each of the formats and their respective extensions.

JSON | .json | Returns The output serialized in JSON, using a Europeana specific schema for representing EDM data. | JSON-LD | .json-ld | An alternative JSON output based on the JSON-LD format for RDF. | RDF/XML | .rdf | The XML output is primarily based on RDF/XML format for RDF serialization but following the EDM XSD schema (the same schema is also used for data ingestion to Europeana). |

Error Responses
An error occurring during processing of an API method is reported by (1) a relevant HTTP status code, (2) a value of the success field and (3) a meaningful error message in the error field. The following table shows the fields appearing within an error response:

JSON is the primary output format of the Record API. It uses a Europeana-specific schema for representing EDM data.
A response in JSON will always contain several fields that present information about the handling of the request, while the concrete information about the record is presented in the "object" field.

Datatype | Description |

Boolean | true or false | Number | integer or double precision floating-point number | String | double-quoted Unicode, with backslash escaping | Array | an ordered sequence of values, comma-separated and enclosed in square brackets; the values do not need to be of the same type | Array([Datatype]) | an ordered sequence values of Datatype (e.g. String or Object), comma-separated and enclosed in square brackets | Object | an unordered collection of key:value pairs with the ':' character separating the key and the value, comma-separated and enclosed in curly braces; the keys must be strings and should be distinct from each other | LangMap | A special datatype to provide values in various languages. It is an associative array where the keys are ISO language codes or "def" (where the language is not given), and the value is an array of strings. For example: "dcTitle": {"por": ["Paris"]} . Here the datatype of dcTitle is a LanguageMap: the language code is "por" (stands for Portuguese), and the value is a list with only one element: "Paris". For those familiar with Java notations: is it the JSON equivalent of Map<String,List<String>> | null | empty value |

JSON-LD stands for JSON for Linking Data and is one of the Linked Data formats that the Record API supports. The basic structure of the JSON-LD response is similar to the default JSON format of the Record API:

The big differences between JSON and JSON-LD are
JSON-LD makes use of Internationalized Resource Identifiers, IRIs as property names. This ensures that each statement of a record matches a standard vocabulary. In Europeana's implementation the properties are qualified names (in the format of "namespace_prefix:property_name" such as "dc:creator") for the sake of brevity. In the normal JSON response we use non-standard camel case ("dcCreator") property names. In the JSON Section you can find the connections between our camelCase property names and the JSON-LD and RDF qualified names.
JSON-LD has a @context
part, which links object properties in a JSON document to concepts in an ontology. In our JSON-LD this lists the used namespaces and their prefixes.
JSON-LD makes a distinction between values that are string literals from values that are other resources.

Retrieving a Record in the RDF/XML format
The XML output is primarily based on RDF/XML format for RDF serialization but following the EDM XSD schema (the same schema is also used for data ingestion to Europeana).
The structure of an RDF/XML document formated using the EDM XSD schema is as follows:
The root element of the XML document is "rdf:RDF". This element will have declared all the namespaces required for the qualified names of all classes and properties being using within the document. A list of all supported namespaces can be view in our EDM introduction.
...
Within the root element, all instances of EDM classes are declared using the qualified name of the classes as the label for the XML element. An "rdf:about" attribute is present indicating the IRI of that instance.
Retrieving thumbnails from Media Resources
The Thumbnail API is an extension of the Record API to allow the retrieval of cached thumbnails that are generated upon ingestion of the metadata by Europeana. Thumbnails are only generated for media resources that are referred through by edm:isShownBy, edm:isShownAt or edm:object properties which are then supplied using the edm:preview property.
Request
The Thumbnail API doesn't require any form of authentication, providing your API key is optional. It always returns an image, whether the thumbnail exists or not. To use the Search API to verify whether a thumbnail exists you can add has_thumbnail=true to your search query, or check if the edmPreview field in the search or record response has a value (which is the URL of the thumbnail).
Every call to the Thumbnail API is an HTTP request in the following URL signature:
https://api.europeana.eu/thumbnail/v2/url.json?uri=URI&type=TYPE&size=SIZE
where the variables in the URL path mean:
Parameter | Datatype | Description |
---|
size | String | The size of the thumbnail, can either be w200 (width 200) or w400 (width 400). |
type | String | Type of the default thumbnail (media image) in case the thumbnail does not exists, can be: IMAGE, SOUND, VIDEO, TEXT or 3D. |
uri | String | The URL of the media resource of which a thumbnail should be returned. Note that the URL should be encoded. |
Response
The thumbnail API call responds with an image in the given size. If the thumbnail does not exist, the API returns a 'default' image which is specific to the 'type' that is provided.
...

String | Values are preserved as they are present in the data. |
The following will be deprecated per the given date, ensure that your API clients are updated accordingly:
Date | Deprecation Details |
---|
January 2018 | As the API supports SSL now for a while, we will start to redirect all non-SSL traffic for the API to SSL. Ensure your applications follow redirects if needed or adjust the hostname to use SSL. |
Roadmap and Changelog
We deploy new versions of the portal and API quite regularly, but not all new versions result in changes in the interface.
