I've been using tags here right from the beginning, because they provide a much more powerful and flexible way of categorising content than do simpler more static categories. This seems to be pretty much the consensus in the blogosphere now.
I started off using xtaran's
tagging plugin. The one thing I
didn't like about
tagging was that it has a fairly brute-force
approach to doing tag filtering - it basically just iterates over the
set of candidate files and opens up and checks them all, every time.
So I started messing around with adding some kind of tag cache to
tagging, so that the set of tags on a post could be captured
when a post was created or updated, and thereafter tag filtering
could be done by just referencing the tag cache. That means that
if you've got 100 posts, your tag query only needs to read one file -
the tag cache - instead of all 100 posts.
En route I realised I really wanted a more modular approach to
tagging than the
tagging plugin uses as well. For instance, I'm
experimenting with various kinds of
data blogging, like using dedicated
special-purpose blogs for recording bookmarks or books or photos.
And for some of these blogs I wanted to be able to do basic tagging
and querying, but didn't need fancier interface stuff like
So I've ended up creating a small set of blosxom plugins that
provide most of the functionality of
tagging using a tag cache.
The plugins are:
tags- provides base tag functionality, including checking for new and updated stories, maintaining the tag cache, and providing tag-based filtering. Requires my
storytags- provides a story level $storytags::taglist variable containing a formatted list of tags, suitable for inclusion in a story template. Requires
tagcloud- provides a $tagcloud::cloud variable containing a formatted wikipedia:"tagcloud" of tags and counts, suitable for inclusion in a template somewhere. Requires a hashref of tags and counts, which
tagsprovides, but should be able to work with other plugins.
Note that these plugins are typically less featureful than the
tagging plugin, and that
tagging includes functionality
(related tag functionality, in particular) not provided by any
of these plugins. So
tagging is still probably a good choice
for many people. Nice to have choice, though, ain't it?
