Metadata Tier C

Metadata Tier C (Europeana website as a knowledge platform)

To offer users the best possible experience when working with your collections online, at least 75% of your metadata elements that are relevant need to have at least 1 language tag. The metadata should include at least three distinct enabling elements covering at least two distinct discovery and user scenarios and two distinct contextual classes with all minimum required elements or links to LOD vocabularies (also with all minimum required elements).

2 Enabling elements
3 Contextual classess

At least 75% of the metadata elements from ProvidedCHO that are relevant have at least one language qualified value

Enabling elements

At least four distinct metadata elements taken from two distinct ‘Discovery scenario’ groups present in the edm:ProvidedCHO class

Contextual classess

At least two contextual class with all minimum required elements, OR link to a LOD vocabulary we support.

Contextual resource referred by the ProvidedCHO: A contextual entity (an instance of a contextual class such as edm:Agent, skos:Concept, edm:Place, edm:TimeSpan) that is linked directly from edm:ProvidedCHO (ie. Provider's ore:Proxy) and therefore ignoring contextual resources that are only linked from other contextual resources via e.g. placeOfBirth.

Contextual classess	Minimum required metadata elements per contextual class
edm:TimeSpan	edm:begin AND edm:end
skos:Concept	skos:prefLabel AND (skos:broader OR skos:narrower OR skos:exactMatch OR skos:closeMatch OR skos:related OR skos:note)
edm:Agent	skos:prefLabel AND (edm:begin OR rdaGr2:dateOfBirth OR edm:end OR rdaGr2:dateOfDeath OR rdaGr2:professionOrOccupation OR rdaGr2:placeOfBirth OR rdaGr2:placeOfDeath)
edm:Place	skos:prefLabel AND wgs84_pos:lat AND wgs84_pos:long
