Europeana Data Model
On this page you find all the documentation you need about the Europeana Data Model (EDM).
General EDM factsheet and Presentation
The EDM Factsheet and an EDM presentation sum up the rationale and expected benefits of EDM.
EDM Primer
The EDM Primer is the 'story' of EDM and explains how the classes and properties may be used together to model data and support Europeana functionality.
EDM Mapping guidelines
The EDM Mapping Guidelines give guidance for providers wanting to map their data to EDM. They contain definitions of the properties, information about the data types that can be used as values and the obligation level of each property. This documentation also has an example of original data, the same data converted to EDM and diagrams showing the distribution of the properties amongst the classes, as well as other EDM examples specific for content and metadata tiers. The full set of EDM classes and properties are being implemented incrementally, this documentation shows those that are currently available.
EDM objects templates
The EDM object templates below shows which properties apply to which class and states the data types and obligation of the values. These templates should be regarded as a work in progress however and may be out of step with the Mapping Guidelines. Please refer to the Mapping Guidelines for the current set of classes and properties in use.
To create EDM data providers should follow the EDM Mapping Guidelines at 
Europeana Data Model | Europeana PRO
Note: Properties that are not shown in bold type will not be implemented.
For introduction and general documentation on this page, see Europeana Data Model | Europeana PRO . The corresponding XML schema can be accessed at https://github.com/europeana/metis-framework/tree/develop/metis-schema/src/main/resources/schema_xsds
Note: in the following all resources have identifiers, which are left implicit in the documentation. These identifiers could be "external" identifiers, e.g. HTTP URIs.
Core EDM resources
edm:ProvidedCHO
To create EDM data providers should follow the EDM Mapping Guidelines at Europeana Data Model | Europeana PRO
Quite often this may be a resource of type edm:PhysicalThing as well. This should be indicated using a specific rdf:type statement.
All descriptive metadata for the ingested object will be represented attached to the proxies in the Europeana information space. Only the owl:sameAs, meant to enable providers to point to their own (linked data) representation of the object (e.g., for the Swedish aggregator's linked data or the Nat. Lib of Hungary), would remain attached to the central CHO node.
