Hi Chris,

Currently the website builds source.json by using 'fold-packages'
(traversing all the modules and returning all the public variables, if I
read correctly) then excluding 'package-superseded' and
'package-replacement'.

Well, maybe an example is simpler than a lot of words.  The resulting
JSON looks like:

--8<---------------cut here---------------start------------->8---
    {
      "type": "url",
      "urls": [
        "https://ftpmirror.gnu.org/gnu/a2ps/a2ps-4.14.tar.gz",
        "ftp://ftp.cs.tu-berlin.de/pub/gnu/a2ps/a2ps-4.14.tar.gz",
        "ftp://ftp.funet.fi/pub/mirrors/ftp.gnu.org/gnu/a2ps/a2ps-4.14.tar.gz",
        "http://ftp.gnu.org/pub/gnu/a2ps/a2ps-4.14.tar.gz"
      ],
      "integrity": "sha256-866NPUVkpBtuKiHyN9LysQT0gQhZHouDSXUAGCo6s6Q="
    },
    {
      "type": "git",
      "git_url": "https://github.com/opencog/agi-bio.git",
      "git_ref": "b5c6f3d99e8cca3798bf0cdf2c32f4bdb8098efb"
    },
--8<---------------cut here---------------end--------------->8---

So basically, the data are: origin-method, origin-uri (implies reference
URLs and {git,hg,svn}-{commit,revision}), origin-hash (implies
content-hash-{value,algorithm}).  Note that the list of mirrors are
necessary too.

I have given a look to

  http://git.savannah.gnu.org/cgit/guix/data-service.git/tree/

but I am not sure to understand where the SQL table is defined.


Thanks,
simon
