I see. Glad to hear then.
What do you think about multiple label "l" structure that i have shown in language or topic labelling? Do i need to change something in those cases?
Example:
Note/post which has multiple languages
["l","en","ISO-639-1"], ["l","ja","ISO-639-1"]
Note/post which has multiple topics
["l","science_and_technology","app.nfrelay.topic"], ["l","arts_and_culture","app.nfrelay.topic"]
