I do not see the wdtn prefix used in the Wikidata Query Service. For instance, This gives zero results:

SELECT
  ?s ?o
WHERE {
  ?s wdtn:P5822 ?o .
} 
LIMIT 10

Try it!

Is there something that I am missing?

Looking which properties have a "DirectClaimNormalized" predicate in the query service : https://w.wiki/9fQA it seems only identifier properties have this normalization.

Thanks, I see now.

SELECT 
  ?s ?o
WHERE {
  ?s wdtn:P212 ?o .
}
LIMIT 10

Try it!

Gives a result. I thought that amount properties would use wdtn for SI conversion
