Tip #5 : Taxonomy in WordPress 2.3
Posted by Leonid Mamchenkov on August 27, 2007
The upcoming release of WordPress 2.3 introduces a new way of tagging and categorizing posts and links. It replaces the old way of categories and should provide enough flexibility to replace a whole bunch of plugins. Or, at least, make those plugins much simpler.
This new feature required a few changes in the WordPress database scheme. Gladly, Ryan Boren has posted the description of changes in the database structure.

It would be great if there would be a way to easily migrate from Ultimate-Tag-Warrior-Tags to the new built-in taxonomy.
Will the necessary migration-tools be included in 2.3?
Leonid Mamchenkov said
Jan,
yes, from what I know, WordPress 2.3 will have a migration tool for UTW plugin.
Jan said
This is very good news!

It will migrate the tags, but after it does that, UTW will be useless and will have no use (including things such as tag clouds.) The author did suggest she was going to modify those features to work with the new system.

This taxonomy thing is pretty straight forward for simple stuff like categories and tags. I have a feeling that it has a lot of potential for the non-obvious uses, but I’m still trying to wrap my head around it… ;)

If an example is needed of accessing tag information in 2.3, beyond what Kubrick does, check out Sandbox 1.0. Might be helpful.
Leonid Mamchenkov said
Scott,
thanks! I’m sure there will be a lot of interest for an example, once WordPress 2.3 is released. :)

Hi,
What about Simple Tagging plugin. This is better plugin (IMO) then UTW and supports import of UTW tags. Will it WP 2.3 support import of Simple Tagging tags?
Thanks
Leonid Mamchenkov said
Dejan,
right now there is a discussion on Trac (that’s where WordPress bug tracking and development happens) on whether the importer for Simple Tagging plugin should be available in the core when WordPress 2.3 will be released, or if it should be left for a plugin. You can cast your vote and voice your arguments here:

Other than the taxonomy implementation in WordPress 2.3, I have no idea what significance will it have on my site. Also, I am using All-in-One SEO Pack, I am still investigating if that may have any effect on this plugin.

You say : ” I have a feeling that it has a lot of potential for the non-obvious uses”…
I have exactly the same feeling, but I still do not have the answer.
Apart from making things easier for tagging, I am sure it will enable to imagine different classification techniques within a blog… Do you think that we could imagine other kind of object others than category, tag and blogroll ?
