Jsonl base export structure

,
1

I did a NER revision of a base and now in the export I have what seems to be the original annotations and another annotation version, in the 'version' key. I'm insecure.
What is the latest data for training?
Do I just leave the 'version' and remove everything else?
In training, is the latest version automatically used?

Start like this:
inicio

In the 'version' part:
version

In this example here, there are 4 versions, they are marked in the text:
Which of these versions is the most current, since it has no timestamp?

versions
versions1055×920 38.2 KB

(the text is blank because it is confidential information)

That's interesting. Does your original task not have a timestamp attached?

I just tried the review command on a text classification dataset. The original blob looks like this.

{
	"text": "@Tesco 3/3 on the wrong which I really don\u2019t appreciate. This needs to be investigate and I was simply queuing to pay and the guy pushed in\ud83d\ude21",
	"_input_hash": -1341474668,
	"_task_hash": 1319679126,
	"options": [{
		"id": "product",
		"text": "\ud83d\udce6 sold product"
	}, {
		"id": "delivery",
		"text": "\ud83d\ude9a delivery"
	}],
	"_view_id": "choice",
	"config": {
		"choice_style": "single"
	},
	"accept": [],
	"answer": "ignore",
	"_timestamp": 1647886842
}

You'll notice that there's a _timestamp key attached to the original. When I pass this through review it looks like this:

{
	"text": "Ay @Tesco what\u2019s your policy on bottles of lemonade? 6 bottle max is a bit of a joke am thirsty",
	"_input_hash": -1402913396,
	"_task_hash": -768177885,
	"options": [{
		"id": "product",
		"text": "\ud83d\udce6 sold product"
	}, {
		"id": "delivery",
		"text": "\ud83d\ude9a delivery"
	}],
	"_view_id": "review",
	"accept": ["product"],
	"config": {
		"choice_style": "single"
	},
	"answer": "accept",
	"_timestamp": 1650614258,
	"_session_id": "tesco-support",
	"sessions": ["tesco-support"],
	"versions": [{
		"text": "Ay @Tesco what\u2019s your policy on bottles of lemonade? 6 bottle max is a bit of a joke am thirsty",
		"_input_hash": -1402913396,
		"_task_hash": -768177885,
		"options": [{
			"id": "product",
			"text": "\ud83d\udce6 sold product"
		}, {
			"id": "delivery",
			"text": "\ud83d\ude9a delivery"
		}],
		"_view_id": "choice",
		"accept": ["product"],
		"config": {
			"choice_style": "single"
		},
		"answer": "accept",
		"_timestamp": 1647886847,
		"_session_id": "tesco-support",
		"sessions": ["tesco-support"],
		"default": true
	}],
	"view_id": "choice"
}

As you can see, the _timestamp key is also copied inside of the versions list. How did the original json blob get created? Is there a reason why the _timestamp key would be missing?
