Seme4 Platform ============== We're relying on (ancient) `EasyRDF `_, which has not been well maintained in recent years. Also now running PHP 8.3 which is a lot fussier about type-hinting function arguments and return values, which causes all kinds of issues with legacy code. There's a script `php8-fixes.php `_ that somewhat crudely applies changes to fix some errors and shut up the warnings... it's a bit of a horror show and probably needs revisiting in the course of time. Shout if you see any deprication warnings in use! See also `platform setup `_ though it's very old!
