Re: author specification
Message ID:
Hi Brad,

There is no password or other cryptographic way, so authentication is 
not possible. Obviously, I might miss some insight here.

In the documentation I read; "|:auth| generally takes the form 
|hosting:ID|, as in |github:github-user| or |gitlab:gitlab-user|". For 
me, hosting is e.g. on GitHub or Gitlab to store the software, and 
ecosystems are for spreading the word, i.e. telling that there is a 
software available somewhere, and this somewhere is not important. That 
is the work for zef to find out.

And the word 'generally' means that it is just an example, it is in the 
end just a string.
Furthermore, there is no mention in the docs of any use other than 
naming it in a useful way. No remarks of needing it to login into some 
ecosystem and no word about that separator, being a column, or split it 
up in more than two fields using an other character.

Searching through some distributions I find 'zef:lizmat', 
'github:MARTIMM', 'tonyo', 'cpan:WARRINGD', 'github:ccworld1000,,', showing that there is 
absolutely no clear way to use that field. For me, it means again that 
the auth field must be completely free and the same, independent of the 
ecosystem in use.

The word 'github' is longer.

I didn't want to say that it was a bug, sorry for the confusion.

Do you want to write several meta files with different auth fields 
depending on the ecosystem you want to send it to? The only thing you 
can do without much work is sending a project e.g. to fez and another to 
cpan but I don't see the use of spreading your projects over several 

Also for a class you wrote, JSON::Class, what should I write (I took it 
to the extreme of course, 'use JSON::Class' would do)

use JSON::Class:auth<cpan:BGILLS>;
use JSON::Class:auth<github:b2gills>;
use JSON::Class:auth<fez:b2gills>;

All three are getting the same software, or not, when it is someone 
els-es auth.

That is the point I want to make. Keeping the auth field the same 
everywhere, independent of ecosystem, will show that the software is the 
same everywhere. If that someone has the same account name as someone 
else on cpan or fez it will show a difference in the auth field.

So, I think there is a lot to ponder over....
