> This system was one of the oldest IT systems in NAV, and ran in production for 51 years, from when the National Insurance Scheme was introduced in 1967. In January 2018, Presys was put into production, which together with Pesys became the successor to DSF. At that point, DSF was also shut down.
The system is written in PL/I.
It's like the Apollo 11 code, but for social services.
I see mostly Java/Kotlin and Maven.
Pretty modern stack. I would start a government service using those today.
He is probably talking about this repo: https://github.com/navikt/DSF

Mostly PL/I but a few files of COBOL too, e.g. https://github.com/navikt/DSF/blob/main/src/GML/FO04D1X1.cob...
Who needs a Jones Act when you can have processes like these?
