Wikidata:WikiProject Languages/Data model

This is a draft description of how items for languages are modelled in Wikidata.

Labels

Labels should not include words like "language" when it is used for disambiguation. Labels in Wikidata do not have to be unique and are not expected to be identical to the linked Wikipedia article names.

More information: Help:Label

Examples:

German (Q188)

In English, the label is "German" because language names do not normally include "language". People say things like "They're learning German", and not "They're learning German language". The English Wikipedia page is "German language" but this is necessary because page names have to be unique and "German" is a disambiguation page.

In German, the label is "Deutsch" (German) for the same reason as English. The German Wikipedia page is "Deutsche Sprache" (German language) and "Deutsch" is a disambiguation page.

In Japanese, the label is "ドイツ語" (literally: Germany language), because language names are typically formed by adding "語" (language) to a location. This is not disambiguation because without "語", it would mean something different.

American Sign Language (Q14759)

In English, the label is "American Sign Language" because "Sign Language" is normally part of the name of a sign language. People typically say things like "They're learning American Sign Language", and not "They're learning American Sign" or "They're learning American". Since it's part of the name, the words are capitalised.

Descriptions

Descriptions should help people identify the item and distinguish it from other similarly named ones. For languages, descriptions typically include the language family and where it is spoken.

Although languages are often closely connected to particular ethnic groups, it is generally not useful to include ethnic groups in the description. The language and the ethnic group often share the same name, and people are not likely to be familiar with the language but not the ethnic group, or vice versa.

Examples:

• Koro (Sino-Tibetan language spoken in India)
• Koro (Oceanic language spoken in Papua New Guinea)
• Koro (Oceanic language spoken in Vanuatu)
• Koro (Mande language spoken in Ivory Coast)
