Table of Contents

The datatype Monolingual text1 associates a text value with a specific language code. The annotation form is expected as foo@en with the first element being an arbitrary text while the second element divided by @ to contain a valid language code.

Notes

• An annotation with [[Has monolingual text::some text@en]] is identical to [[Has monolingual text::some text@EN]] because language codes are transformed to a IETF language tag / BCP47 (by "Localizer::asBCP47FormattedLanguageCode").
• The Language code is internally managed by special property "Language code"Handles BCP47 conform language codes specifying the language of the annotated text
• Internally each value of this special property ("MonolingualTextValue") is stored as separate entity using as special construct ("ContainerSemanticData") allowing for foo@en to be different from foo@ja by its data structure (oppose to a string comparison which only would establish that two strings are different but without the semantic interpretation that for the cited example only the language code is different).
• The printout can be defined with the option [Help:Ask_syntax/Language_filter|lang], e. g. ?Has monolingual text|+lang=de for a German language printout.
