aeoi (UEk)
React and TypeScript MVP for handling AEOI DAC2 and CRS XML files; validation stubbed, a demo.
What it does
A demo for AEOI (automatic exchange of information) XML files in DAC2 and CRS formats: upload, validation, cases and tasks, SEK and EUR conversion and tax number search. It is React and TypeScript on Supabase and needs Node 18 or later and a Supabase project. The README calls it an MVP for education: XML parsing and XSD validation are stubbed, there is no authentication and no licence is named.
Licence unknown: we found no licence we could recognise. Check with the maintainers before you reuse the code.
Where it fits on the map
Not on the map: a demo.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
