Suggestion for a reliable yet portable modstore

gistfile1.txt

Add a modlist to minetest e.g.

https://github.com/minetest/modlist/modlist

Content is supposed to be json (... yes ... I know ... I hate it myself too ;-) ):

a simple example:

<<< FILE BEGIN >>>
{
    {
        "name" : "Mod1",
        "type" : "github",
        "url"  : "https://github.com/mod1",
        "validated_versions" : {
            {
                "tag" : "0.0.1",
                "min_minetest_version" : "0.4.10",
                "md5sum" : "......",
                (OR "sha256" : "......",)
            }
        }
    }
}
<<< FILE END >>>

Each mod is supposed to provide a mod description in it's repository. 
This file is supposed to contain all official versions. 

Example:

<<< FILE BEGIN >>>
{
    "current_version" : "0.0.7",
    "current_doc_version" : "0.0.3", 
    "versions" : [
        {
            "tag : "0.0.1",
            "description : "Initial version of mod",
            "main_screenshot : "http...",
            (optional "screenshots" :  [ "url1", "url2", "url3" ],
            "min_minetest_version" : "0.4.6"
        },
        {
            "tag" : "0.0.2",
            "description" : "Fixed version",
            "main_screenshot" : "http...",
            (optional "screenshots" : [ "url1", "url2", "url3" ]
            "min_minetest_version" : "0.4.6"
        },
        {
            "tag" : "0.0.3",
            "description" : "Test mod for example",
            "main_screenshot" : "http...",
            (optional "screenshots" : [ "url1", "url2", "url3" ]
            "min_minetest_version" : "0.4.7"
        },
        {
            "tag" : "0.0.4",
            --use 0.0.3 description
            "min_minetest_version" : "0.4.9"
        },
        {
            "tag" : "0.0.5",
        },
--{ "tag" : "0.0.6" } removed because of totally broken
        {
            "tag" : "0.0.7",
            --use 0.0.3 description
            "min_minetest_version" : "0.4.10"
        }
    ]            
}
