Clarification empty string

[Haatschii]

The specs are not 100% clear in my opinion, regarding empty strings. Are those valid Jason Lines?

The second bullet point in the specs says

Each Line is a Valid JSON Value
The most common values will be objects or arrays, but any JSON value is permitted.

This allows two viewpoints:

• An empty string is invalid, as the first and only line is no valid Json value.
• It is valid, as there are no lines at all, therefore all lines are valid.

The Validator on the website says it is valid. However it is also somewhat contradictory because a single /n is shown as invalid, although bullet point 3 of the spec says that a single /n at the end of the file is ignored, therefore either both ("", and "/n") should be valid or invalid.

Could you provide some clarification?

I agree with @Haatschii, that empty input should be valid, because JSON Lines is essentially defining an array. If you have an array of arrays there would be no way of indicating a zero length top level array.

Thank you we should word this so that it's clear. An empty file is valid but a file with only \n is not because \n indicates the end of a valid record. Any suggestion on better wording?
