Dependent/Conditional (?) Taxonomy

Hello folks,

I need some advice on how to structure a site that has photos of airplanes. Now say I want to have photos of airplanes that users can browse either by airline, manufacturer, or age? A traditional taxonomy structure would look as follows:

US Airways
-Airbus
--A320
--A330
-Boeing
--737
--757

American Airlines
-Airbus
--A330
-Boeing
--747
--757
--777

(Hypothetically speaking)

Proposal for a module: TAC fields

I'm considering developing a module to extend the functionality of TAC to role/field combinations. TAC works wonderfully for controlling access to whole nodes based on their taxonomy, but it's all-or-nothing; the module currently has no way of leveraging the per-field access control offered by Content Permissions.

I don't think the functionality belongs in TAC itself, as my proposed module is an additional layer of complexity that's specific to CCK content types.

Automated Readers Advisory - Taxonomy or Node Reference

I was wondering if anyone had any experience building something for automating readers advisory. My librarians are calling it "read-a-likes." The idea is that there is a list of authors. Each author would link to their page with links to other similar authors. You can see the example below.

If you like David Baldacci, then try:

William Bernhardt
Stephen J. Cannell
Linda Fairstein
Vince Flynn
James Grippando
John Grisham
Brad Meltzer
Kyle Mills
Robert Tanenbaum
Stuart Woods (Will Lee Series)

A further example can be found here.

Dealing with really large taxonomies and term relations to handle term metadata

Been a while since I browsed around the taxonomy group and thought it a good time to write a bit about what has come of the Taxonomy Sprint in Chicago last year re: large taxonomies and term relations / term metadata with respect to the Encyclopedia of Life. We soft launched LifeDesks (http://www.lifedesks.org) whereby anyone may create their own. To get a sense for what's transpired and how we deal with taxonomy, check out a recent YouTube video: http://www.youtube.com/watch?v=-QHSvYrP0O4.

Display a taxonomy image block when viewing the list of a term?

The taxonomy image block is usually shown only when viewing a node (full page view). Is it possible to show it, when viewing the list of nodes of a certain taxonomy term?

Taxonomy Manager 2.0 released!

The last month I've been working on some new features for the Taxonomy Manager. This new major release includes new features like an optional double tree interface (see screenshot), where you can display two trees side by side and perform operations between the two trees. The double tree interface supports operations to move terms in hierarchies, to add new translations and to switch terms between different vocabularies.

Max number of Taxonomies?

I'm curious if anyone has ever ran into a site or project where they went taxonomy crazy where there were TOO many taxonomies on a node?

3-4 Categories can be common and useful, but at what point do the taxonomies become a burden to performance? 10? 50?

Gut feeling says 5 or less would be optimal, but is it ok to have 10 or 20? I'm curious to get people's thoughts. If anyone has used a ton of taxonomies in a project I'm curious if it worked out for their site. Any links to articles/posts about the topic would be helpful too.

thanks!

taxonomy.module on line 70 error message

Hi all

Been trying to figure this wried error message everytime a user uploads a file. I did ask in the drupal forums but no one seems to know what to do.

when a user uploads a flash game on the site, it has a error message above of it:

/home/content/X/X/X/'database username'/html/modules/taxonomy/taxonomy.module on line 70.

it now displays the error message twice in one page.
I did try to re-upload the taxonomy module with a fresh new one but no signs of the error message going away. Can other modules like views or CCK can cause this error?

taxonomy_access_user module review

Hi drupal !

I'm posting here to request a review of a module i'd just coded and that i would
like to submit on drupal.org. Before doing this, i would like someone to review
my module. Even if i'm pretty confident with my code which i've been testing for last
2 weeks, i would prefer others' advice.

About the module :
This module provides taxonomy based user control for user but unlike modules already
available on drupal.org with inheritance notion. For more information please read the
README (available below).

Thank you by advance.

Code is available here on github : http://github.com/baloo/taxonomy-access-user
Or as a tgz : http://github.com/baloo/taxonomy-access-user/tarball/master

Vocabulary Relationships / Hierarchy and Usability

I've been trying to wrap my head around this for a while and I'm running into a roadblock in terms of providing good usability to community members vs. correct information architecture. As an example, let's say I'm running a website about plants, and visitors can add articles about different plants. This is just a crude example to help understand the problem. When a visitor goes to create a new article, they can categorize it as follows:

Plant Part
- Color
-- Produce

D7: Term field upgrade and migration strategy

With some kind of CCK Field UI going into core and taxonomy term field going in hopefully soon, we can really resolve the problems related to upgrade path. Please volunteer if you can! Here are the principles I'm drawing out of the discussion so far:

Data migration

  • For each vocabulary, create a field.
  • For each row in taxonomy_vocabulary_node_type create a field instance for that vocabulary's field on that node type's bundle.
  • For each row in taxonomy_term_node, save a row in appropriate field instance's table.

How to style a single-select dropdown?

Hey,

I originally posted this question here: http://drupal.org/node/507724, but got no response, so I am trying in this group. I will of course post a write up of the solution in the original post if I get one here 8o)

Does anyone know how to style a single-select dropdown, which is based on a taxonomy vocabulary?

As it is now, the styling is a dash added in front of the child terms, like this:

Parent
-Child
--Grandchild
-Child
-Child
Parent
-Child

Ideally I would like to style the parent term bold, to really make it stand out and clarify where a new category begins.

Cross vocabulary hierarchy

Hi all,

Is there a way to make vocabularies hierarchically dependent, so that their terms would inherit this hierarchy?

Example:

voc 1: Countries
  voc 2: Cities
    voc 3: Theaters

Now for tagging an event we first select Country, then City, then Theater.
I found no solution for this on D5, now I'm on D6.
Any ideas (patches are welcome too)?

And, of course, having this working together with http://drupal.org/project/hierarchical_select would be great.

p.s. Thing which is not an option - placing terms in one vocab.

Tagging comments?

Hello!

I'm curious - is there a good (and ideally easy) way to incorporate tagging of comments?

I'm thinking D6 here. Is node comment a good way to go? the only way to go?

Has anyone been down a similar road before? Any pitfalls?

Looking forward to any tips you might have!

Thanks!
