Notes

For technical reasons, it is mandatory to specify the media type (in LIDO: <lido:resourceType>/<lido:term>) when publishing to portals such as German Digital Library and Europeana. Only one media type can be specified per media file.

The media format (MIME type) should additionally be specified in a separate data element (in LIDO: Attribut lido:formatResource> of the element <lido:linkResource).

Comparison with relevant standards and database models

Standard	Element name	Text/URI	Repeatable	Obligation level	Comment

Standard	Element name	Text/URI	Repeatable	Obligation level	Comment
German Digital Library: Metadata requirements for data provision	Medientyp [eng.: media type]	Text	No	Mandatory (also IANA media type mandatory)	In contrast to the minimum data set recommendation, in the German Digital Library the Medientyp [eng.: media type does not refer to the digital representation, but to the cultural heritage object. For example, if the cultural heritage object is a postcard, the media type for a data delivery to the German Digital Library must be "Text", regardless of whether the media file is a PDF or a JPG. In addition, the IANA media type (MIME type) must be specified for data deliveries to the German Digital Library. This should be provided via the attribute value of formatResource.
German Digital Library LIDO application profile (DDB-LIDO)	<resourceSet> / <resourceType> / <term>	Text	No	Mandatory (also IANA media type mandatory)
