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: <lido:linkResource @lido:formatResource>).

Comparison with relevant standards and database models
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. |
Text | No | Mandatory (also IANA media type mandatory) | |||
| DFG Basic Data Record | Digital Copy Media Type and Format | Text (controlled vocabulary) and/or URI | Not specified | Mandatory | Media type and format are combined in the DFG Basic Data Record; a specification according to https://www.iana.org/assignments/media-types/media-types.xhtml is preferred. |

| digiCULT | MIME Type | Text | No | Mandatory | The media type in digiCULT is derived from the format specification (MIME type). |
| museum-digital | (No match) | Text | No | Mandatory | The media type is selected in museum-digital when a resource is uploaded: If an image is uploaded, this corresponds to the media type "image"; if a video is uploaded, this corresponds to the media type "video". |
