For taxonomy terms, how you name them will depend on whether or not the terms are exposed on the site.
If the term is exposed on the site:
Taxonomy terms can be exposed if they appear in the categorizer section of Dynamic Content Lists (DCLs) or in other places like research interests. For the title of terms that are exposed, simply provide the title that you want to have appear to visitors of your site. Make sure to translate the term into French.
Tip: You may wish to hierarchize terms that are exposed under a parent term to group them together. This can help provide context and make it easier for users to understand where the terms are used.
If the term is not exposed on the site:
Most terms that you create will not be exposed on the site. Given this, you can follow the same naming convention as General Content Snippets. That is, enter the page name, followed by an interspaced hyphen, and then the name of the element.
For example, if you were creating a taxonomy term for a slideshow on the home page of your site, the term's title should resemble "Home - Slideshow".
