I don't have the latest Jack with metadata.
Can you tell me what kind of data exists now?
Malformed question. The metadata API exists for users (or systems) to add
arbitrary data. So no data "exists now".
If I ask a hardware port for its metadata, will I see
useful data
like port names?
Depends on whether any was added. I am probably the only person worldwide
to have added pretty-name data, and I'm the only person right now to have a
qjackctl hacked to display them.
Have any conventions been established as to what to
call our properties,
port naming formats, tags etc?
This was all discussed on the jack-devel mailing list last year.
(1) read the output of man jack_property
(2) then add in the fact that well known metadata "keys" were discussed
there, and the idea is for well-known ones to be URIs that resolve to
actual URLs where someone could actually read a description of what the
data is. So for example, we did decide upon http://jackaudio.org/metadata/*
as an "official" namespace, and there was wide support for
http://jackaudio.org/metadata/pretty-name and
http://jackaudio.org/metadata/role (although the 2nd one needs a vocabulary
which is not currently defined).
Unfortunately when we "lost" the drupal jackaudio site due to hacking
earlier this year, we lost the metadata/ part of the website, so the URIs
do not function as URLs right now.
