The 'supported' metric doesn't really translate the same in reference
to open source software as it does to commercial software. When a
commercial software product becomes unsupported (think IE6), then you
are out in the cold. You don't have the source code, so you can't fix
an issue with it, or hire someone to fix the issue. Unless you are
really good with a hex code editor and patching binary files, you're
out of luck.
With open source software like Perl, you may see statements like 'Perl
5.6 is no longer officially supported'. This means you probably won't
be able to get the P5P team to fix bugs or security issues if they
come up. Still, you have the source code, so you can fix it yourself.
CPAN is a bit more murky in that individual authors can decide to
deprecate modules, or they can drop off the face of the earth, but
widely used modules such as Apache::DBI, SOAP::Lite (maintenance
recently stewarded by yours truly) will almost always have volunteers
step up and maintain them, because those volunteers need those modules
to be functioning for own work. In terms of a supported metric, I'd
say modules that are used by more than a few people are supported
100%.
With regards to Apache::DBI, it is very much supported :) But this
comes with the general open source software caveat - "Using open
source software doesn't mean someone will do *your work* for free". If
there's a feature that appeals to more than a couple users, or a bug
that affects more than a couple users, odds are that it will get
fixed. Features that only one user is after will likely not be
implemented by the maintainers, but patches for those features are
usually readily accepted.
