Have you considered using Package URLs?

See https://github.com/package-url and a quickie POC at https://gist.github.com/pombredanne/d3585617882f91d9316be5ce5eddf190

Did not know it.

Package urls are urls to identify a package, example pkg:pypi/[email protected]

That sounds cool. I'd like to implement support for that. Hope around christmas I finally will get some time to work on zpkg and plash

Thanks

Can't offer anything this time, will leave the issue open.
