Dear Carl,
The DEP5 specification is starting to age because I and Steve have not been
very active driving it recently, but I am quite confident that, whatever the
final content of this DEP, it will use a less clumsy denomination than
"superset of RFC2822". Basically, all the comments I made on DEP3 not being a
RFC-2822 format hold there. I think that it will be better to clearly define
the format in the DEP5 itself.
At some moment, I thought it would be possible to write the DEP in a
format-independant manner. This is why there is some part that leaves the
possibility to implement it in YAML. But after experimenting a couple of hours,
I came to conclude that we can not use YAML for a stanza-based format if we
want to be still human-friendly. You can find more details in the following
email, that carries the same conclusion for Debian control files:
http://lists.debian.org/msgid-search/20090801021247.gh4...@kunpuu.plessy.org
for the machine-readable Debian copyright file (DEP5), I actually recomend to
not imitate the syntax of the Debian control files, which is more compact than
the current practices (the dh_make template), and does not alow free-form
comments. I propose a format similar in spirit but more flexible in the
experimental branch of the DEP that I maintain in a git repository (working on
the DEP unfortunately made me strongly allergic to bzr, where it is
maintained).
http://git.debian.org/?p=users/plessy/license-summary.git;a=summary
(every Alioth user has a write access to it).
I attached to this message three minimal copyright files, one using the dh_make
template, the other using DEP5, and the third using the alternative format I
propose for DEP5. I am still not completely satisfied for this format, as it
is very easy to break by forgetting to type some whitespace in the apparently
emptly line between the first line of the License field and the main part.
Have a nice day,
