Notes
This data element indicates the language in which the record is available. It is required for compatibility of the Minimum Record Recommendation with the LIDO harvesting format.
If certain free-text structured information, such as the Object title or name or an Object description, is also available in other languages, this is indicated separately for the corresponding individual data elements. The language labelling of individual data elements will usually have priority over the general language labelling of the data record in the processing of individual elements in portals.
In addition to the language of the dataset and the language labelling of individual data field values, the language of the cultural heritage object can be specified. This is mandatory when delivering data to Europeana for cultural heritage objects with the media type "Text", and it is is implemented in the LIDO element <lido:classification> with the type attribute='language' for data deliveries to Europeana via the German Digital Library. In Europeana EDM, the language of the cultural heritage object is indicated in the EDM element <dc:language>.
In LIDO, the language is not indicated by an element, but by the xml:lang attribute. Two-character language codes should be used for language labelling, if available for the language in question. Alternatively, three-character language codes may be used. This follows the recommendations of W3 and Europeana.
Lists
ISO-639-1 (two-letter language codes) preferred. As an alternative, ISO 639-2 / ISO 639-3 (three-letter language codes) can also be used.

Comparison with relevant standards and database models
Standard | Element name | Text/URI | Repeatable | Obligation level | Comment |
---|---|---|---|---|---|
German Digital Library: Metadata requirements for data provision | (No match) | Not applicable | Not applicable | Not applicable | |
<descriptiveMetadata xml:lang> and <administrativeMetadata xml:lang> | Not applicable: attribute | No | Mandatory | Language labelling is mandatory in LIDO at record level. Therefore, it is also mandatory in the DDB-LIDO application profile. | |
DFG Basic Data Record | (No match) | Not applicable | Not applicable | Not applicable | |
DFG Practical Guidelines on Digitisation: LIDO core metadata | <descriptiveMetadata xml:lang> and <administrativeMetadata xml:lang> | Not applicable: attribute | No | Mandatory (see comment) | Language labelling is mandatory in LIDO at record level. Therefore, it is also mandatory in the LIDO core metadata of the DFG Practical Guidelines on Digitisation. |
Europeana Data Model (EDM) | <edm:language> | Text (controlled vocabulary) | No | Mandatory (see comment) | The element is completed by the Europeana Data Ingestion Team at the time of import, based on the language of the data partner. In EDM, it is also strongly recommended to indicate the language of each element. Like LIDO, EDM provides the language attribute xml:lang using the ISO-639-2 standard for this purpose. In EDM it is also mandatory to label the language of the cultural heritage object for text objects (letters, postcards, brochures, etc.). This is done in the <dc:language> element. |
EODEM application profile | Record Language /lido:descriptiveMetadata/@xml:lang /lido:administrativeMetadata/@xml:lang | Text (controlled vocabulary) | No | Mandatory | |
digiCULT | /lido:descriptiveMetadata/@xml:lang /lido:administrativeMetadata/@xml:lang | Not applicable: attribute | No | Mandatory | |
museum-digital | Language | Text (controlled vocabulary) | No | Mandatory | The language for content and navigation is selected automatically, but can also be controlled using language selectors. |
