This use an old standard for the META-spec, which should not be a
problem.  (I have a very old one also using 1.2 without problems as
well.)  But the 1st line looks a bit incomplete as the spec says:

|The first line of a META.yml file should be a valid YAML document
|header like "--- #YAML:1.0".

Maybe that's the problem?  (Just a wild guess as I'm not really familiar
with the old spec's details.)

If an author releases a new module (or new version) on PAUSE, an indexer
analyses the package including the META-spec (and usually sends a mail
to the author that everything went well, what it indexed etc.).  But
this process can sometimes fail and the author has to restart it
manually.  (I never had any problems though, I just read about it.)

Normally it gets added fully automatically, if the META-spec is correct
and the PAUSE server don't run into problems.

At least those that appear as "name" in the META-spec, yes.

Just my 2 cents.

Best regards, Thomas
