Dear Wikidata List,I am a data science master's student at EPFL. For my semester project, I am working with some of your data.
I realized recently that the JSON dataset from 2021-08-30
("https://dumps.wikimedia.org/wikidatawiki/entities/20210830/wikidata-20210830-all.json.bz2") doesn't have any field named 'modified' (described here: "https://doc.wikimedia.org/Wikibase/master/php/md_docs_topics_json.html").
When parsing the JSON I obtain the following top-level structure :
{
  "id": "Q60",
  "type": "item",
  "labels": {},
  "descriptions": {},
  "aliases": {},
  "claims": {},
  "sitelinks": {},
  "lastrevid": 195301613
}
Which almost matches the one described except for the "modified" field that is missing.

Could you please tell me more about the field and where can I find it?

Kindest regards,

Augustin Kapps
