To provide additional useful facets and filtering of Europeana resources the addition of technical metadata at the level of the WebResource, which was currently absent from EDM, is needed. This specification applies to five media types which Europeana currently supports, namely: Sound, Video, Text, Image and 3D objects. This profile lists the properties that will apply to the WebResource class and an additional class that were defined to support such functionality.
A minimal approach has been adopted to the addition of properties to EDM. Not all functions require the addition of a specific property. Consider for example the filtering of Europeana objects based on the presence of a usable thumbnail. This can be detected by checking for the presence of a URL in the “edm:preview” property (and the resource flagged accordingly in a search system) without the need for a specific EDM property to hold that flag in Europeana’s reference data.
Some values can be used to generate further values and, depending on the stage in the processing of data where this happens, a property may be needed to record the output. For example, the orientation of an image will be generated by processing numeric values given in the height and width properties, giving the result as “Portrait” or “Landscape”. A few properties have been created in the EDM namespace even though similar properties already exist elsewhere (e.g. Exif1 and EBUCore2). This is because the allowable values did not match our requirements at this time (e.g. EDM needs literal values in some cases). These properties are: “edm:hasColorSpace”, “edm:componentColor”, “edm:spatialResolution” and “edm:codecName”.…………………..

EDM profile for technical metadata

An overview of all the technical metadata facets in Europeana Collections can be found at Documentation on the Europeana Search API. The content tiers, i.e. the quality of a media resource as specified in the Europeana Publishing Framework, are calculated on the basis of the technical metadata.
