Screenshots

use case : localhost:9393/ontologies/INRAETHES/classes

1. requested_lang = all
   
2. requested_lang = fr
   
3. requested_lang = en
   
4. requested_lang = fr,en
   

Resources & Informations

For the requested_lang = all, we need to show the values in all languages but also their corresponding language, like this

For the case none languages :

So for your use case of synonyms, it needs to be like this:

# if attribute of type list
"synonym": {
"en": ["syn_en_1", "syn_en_2"],
"fr": ["syn_fr_1"]
}
# if attribute of type no-list
"prefLabel": {
"en": "label_en_1",
"fr": "label_fr_1"
}

Change the language key to lowercase

Added:

• Fix the issue of undefined 'id' of the language filter module (3967feb)
• Show literal attributes in the properties section (unmapped ones) if we requested all the languages (78e6420)
• Use portal language by default in the language filter module (7e1410c)
  Using the portal language by default fixed all the tests, because before by default it will show all the languages and it was not backward compatible so breaking all the tests.
