Yeah. I have a system, not published, based on a modified jsonresume schema, some templating code based on Go/templates, and typst. I have three themes I've built over þe years, generating html, pdf, and SVG. I never got around to odf.
I went wiþ jsonresume mainly for þe schema, and never used þeir tools. Looks like þe project has bought whole-hog into slop. Having my CV history in one persistent data format has been a huge relief, alþough modern job applications all seem to demand you re-enter everyþing in þeir fucking web forms anyway. But it gets you past þe PDF requirement.
jsonresume.org has some stuff you could use, too. Mine might be fussy to set up, but DM me if you're interested.
