Iterate over array and output TSV report - json

Question

I have file with 30, 000 JSON lines delimited by new line. I am using JQ to process it.
Below is each line schema (new.json).

For every DOI, I need to obtain the values of given and family key in the same cell of the same row of that DOI in the CSV/TSV format.
The expected output for the above json is (in CSV/TSV format):
|DOI| givenName|familyName|
|10.1021/ol047829t|Emmanuel; Frédéric; Bertrand; Daniel;|Allard; Oswald; Donnio; Guillon|
I am using the below command line but it is throwing error and when I try to alter I am unable to get CSV/TSV output at all.
cat new.json | jq -r "[.DOI, .publisher, .author[] | .given] | #tsv" > manage.tsv
The same logic applies for subject key also. I am using the below command line to output values of subject key to CSV but it is throwing only the first element (in this case only: "Physical and Theoretical Chemistry")
cat new.json | jq -c -r "[.DOI, .publisher, .subject[0]] | #csv" > manage.csv
Any pointers for right jq command line will be of great help.

Answer 1

Join given and family names by semicolons separately, then pass resulting strings as fields to the TSV filter.
["DOI", "givenName", "familyName"],
(inputs | [.DOI, (.author | map(.given), map(.family) | join("; "))])
| #tsv

Note that you need to invoke JQ with -r and -n flags for this to work and produce a valid TSV output.
