I think that feature could be used to define most tags when applied to
software.  However I think you're right to say that we can make a facet
to look at library features.  libfeature::*, maybe?  libfeature::fft,
libfeature::parsing don't look so well, though :(

You mean, you want to add new tags?  In that case, you can create your
own piece of vocabulary and merge it in the system.  I quote from my
/etc/debtags/sources.list (edited fixing the file: line, which requires
three /, and is wrong in the debtags/sources.list currently in sid)

  # Example of locally maintained custom tag data
  #
  # You can provide your own tag data.  To do so, place a file called
  # vocabulary.gz and a file called tags-current.gz in a directory, and
  # use the directory as a tag source.
  #
  # In the example given below, you would place the tag data in
  # /etc/debtags/mytags/tags-current.gz, and the vocabulary data in
  # /etc/debtags/mytags/vocabulary.gz
  #
  # The format of tags-current.gz is described in the tagcoll(1) manpage
  # and the file is similar to /var/lib/debtags/package-tags.
  #
  # The format of vocabulary.gz is like the Debian Packages file, and
  # the file is# similar to /var/lib/debtags/vocabulary.
  #
  tags file:///etc/debtags/mytags

The tags you put in your custom vocabulary will then be available in
debtags-edit.


Ciao,

Enrico
