IRMA has existed for a while, it's a non-profit spinoff from a Dutch university. But to my knowledge it is nowhere as widely known or accepted by relying parties as DigiD[1], this system is run by the government and based on passing the BSN (citizen service number)[2] to the relying party with SAML. It exists since 2005 and has become quite widespread: I can use it to file my taxes, make an appointment at pretty much any municipality town hall, and log in to my health insurance provider to name a couple of things. Before DigiD, the Netherlands has had a central digital population register since 1994 called the Gemeentelijke Basisadministratie Persoonsgegevens, but before that analogue version of a population register was in use for quite some time as well.
