> Why do we need [[Category:Mathematics]] and [[Category:Biology]]
when we
already have
[[List of xy topics]]?
1) Adding metadata to the article it belongs to makes it easier to
find
and update. Having it elsewhere would in fact add
aditional workload
and
require additional learning, because to verify whether
a
categorization is
correct, people would now also have to check all the
[[List of xy
articles]] page where it could be or has been entered. With a
Category:
approach, they only need to keep an eye on a single
page (the
article),
and the categories themselves are structured through
subcategories and
therefore easy to pick.
2) Category pages are not articles. Like talk pages and meta pages,
they
should be logically separated from articles, which has
numerous
benefits
(easier searching/filtering, counting etc.)
If we accept this principle, we should replace all of the [[list of ]]
entries with [[Category:]] entries.
I'm not quite entirely convinced that the healthiest thing to do is to
separate category/list pages from the main namespace, but it's not a
bizarre concept.
3) In terms of information organization, your approach
leads to
bloated,
big pages (the list of lists is going to be hundreds
of pages long,
the
lists themselves are going to be 30K and more),
whereas the category
approach generates all long pages automatically from the information
stored inside the articles. It is much easier to handle.
That doesn't seem like a great argument--the list of categories is going
to be big and bloated.
Rather than looking for points of conflict, I think the more useful
approach is to try to figure out what our specifications are.
For example, the hackish "list of" approach (which could have been our
"category of" approach--the name is immaterial) has plenty of problems
which we would want an alternative implementation to eliminate, for
example the basic problem of not being in sync with the entries in that
category. If someone makes an entry about a random American actor, he
currently has to check if that actor is listed on the list/category
page.
However, one advantage of the "list of" approach is that it allows
people to make more interesting groupings within the list than simple
alphabetization.
So what I'd like to see (and maybe it's on some meta page I've failed to
check--again the problem with having this discussion not be directly
linkable to Wikipedia content) is what it would look like for some
example entries.
Right now, for example, the Kevin Bacon "What links here" looks like:
* 2003 in film
* A Few Good Men
* Apollo 13 (movie)
* Bacon number
* Cigar Aficionado
* JFK (movie)
* July 8
* List of famous Philadelphians
* List of male movie actors
* List of people by name: Ba-Bd
* Mister Roberts
* National Lampoon's Animal House
* Six Degrees of Kevin Bacon
* Small world phenomenon
* Tony Banks
* William Rufus Shafter
That's a pretty nice set. It's not perfect but ideally I'd like to see
us figure out ways to improve upon "What links here" rather than ignore
it...
