The following are the properties that can be used for the class of ore:Aggregation. This means that they are attributes that apply to the whole set of related resources about one particular provided CHO. For each ore:Aggregation a set of these properties should be provided.
The mandatory properties, namely edm:dataProvider , edm:isShownAt OR edm:isShownBy (at least one should be present, recommened to have both and they can be used alongside each other) , edm:provider, edm:rights, edm:aggregatedCHO, edm:ugc (if applicable) are marked in dark blue.
The recommended properties are marked in dark red.
The optional properties are left in black.
Please provide the properties in the record in the same order given in this document, the metadata validation performed by Europeana requires this order.

Properties for ore:Aggregation
Property name | Description | Value type | Cardinality |
edm:aggregatedCHO | The identifier of the source object e.g. the Mona Lisa itself. This could be a full linked open data URI or an internal identifier. | ref | 1….1 |
edm:dataProvider | The name or identifier of the data provider of the object (i.e. the organisation providing data to an
| literal or ref | 1....1 |
edm:hasView | The URL of a web resource which is a digital representation of the CHO. This may be the source object itself in the case of a born digital cultural heritage object. edm:hasView should only be used where there are several views of the CHO and one (or both) of the mandatory edm:isShownAt or edm:isShownBy properties have already been used. It is for cases where one CHO has several views of the same object. (e.g. a shoe and a detail of the label of the shoe) | ref | 0....n |
edm:isShownAt | The URL of a web view of the object in full information context. An edm:isShownAt must be provided. If there is no edm:isShownAt for an object, there must be a edm:isShownBy. If both are available, provide both. The use of edm:isShownBy is preferred. Providing an edm:isShownAt is strongly recommended in all cases. | ref | 0….1 |
edm:isShownBy | The URL of a web view of the object. An edm:isShownBy must be provided. If there is no edm:isShownBy for an object, there must be a edm:isShownAt. The use of edm:isShownBy is preferred. Europeana generates previews for any direct link to an image file. See Europeana Media Policy or information regarding the specifications of previews. | ref | 0….1 |
edm:object | The URL of a representation of the CHO which will be used for generating previews for use in the Europeana portal. This may be the same URL as edm:isShownBy. See Europeana Media Policy for information regarding the specifications of previews. This must be an image, even if it is for a sound object.
In accordance with Europeana's 2023 data publication approach, objects with edm:type=IMAGE that have no edm:isShownBy nor edm:object will not be published in Europeana. (See also ContentTier 1: Image type ) | ref | 0....1 |
edm:provider | The name or identifier of the provider of the object (i.e. the organisation providing data directly to Europeana). Identifiers will not be available until Europeana has implemented its Organization profile. In the case of the provider LoCloud, which collects data from the data provider Zuidwestbrabants
| literal or ref | 1....1 |
dc:rights | Ideally this should be applied to the edm:WebResource or the edm:ProvidedCHO. It is included here for the conversion of data from ESE where it is not known which object the rights apply to. | literal or ref | 0….n |
edm:rights | This is a mandatory property and the value given here should be the rights statement that applies to the digital representation as given (for example) in edm:object or edm:isShownAt/By, when these resources are not provided with their own edm:rights (see edm:rights documentation). The value for the rights statement in this element must be a URI from the list of available values. Note: rights statements must be exactly as specified there, which means they must start with http and not https. (For assesing rights imformation check Understanding the rights statements used by Europeana | Europeana PRO ) Please note that the object page on http://europeana.eu displays the rights of the digital representation selected in the viewer, which is found in the edm:rights of the WebResource that corresponds to the selected edm:isShownBy or edm:hasView. If there is no such edm:isShownBy or edm:hasView representation available, or if there is one but there is no specific edm:rights attached to it, then by default the page displays the edm:rights attached to the ore:Aggregation. For example, a low‐resolution of a JPEG file could be CC‐BY, while the high resolution version or a video showing the object would be CC-BY-NC. In such cases the rights statements given for the individual web resources would ‘override’ the one specified at the ore:Aggregation level. Any other or

edm:ugc | This is a mandatory property for objects that are user generated or user created that have been collected by crowdsourcing or project activity. The property is used to identify such content and can only take the value “true” (lower case). | literal | 0….1 |
edm:intermediateProvider | The name or identifier of the intermediate organization that selects, collates, or curates data from a Data Provider that is then aggregated by a Provider from which Europeana harvests. The Intermediate Provider must be distinct from both the Data Provider and the Provider in the data supply chain. Identifiers will not be available until Europeana has implemented its Organization profile. In the case of the Erfgoedplus.be, which collects data from Zuidwestbrabants Museum and provides it to LoCloud, the properties would look like this:
