Currently, Arc Tags Service does not support multiple-languages. For each tag you can only define one unique identifier, one slug, and one label.
We would like to be able to define one unique identifier for a tag, and one slug and one label for each language supported.
For example:
Tag ID = 00000001
slug_ES_es = opinion
label_ES_es = OPINIÓN
slug_PT_br = opiniao
label_PT_br =OPINIÃO
slug_EN_us = opinion
label_EN_us = OPINION
The value is to be able to navigate for the content of a tag, no matter the language that content is.
