collective.taxonomy 2.0.0

Data structure

In order to limit both the memory and computation requirements, the term data is contained in exactly one persistent index per language, a mapping from the materialized term path to its term identifier.

The term:

Living Organisms -> Eukaryotic -> Simple multicells or unicells

will be indexed under this path:

"Living Organisms/Eukaryotic/Simple multicells or unicells"

The index allows us to provide an iterator over the sorted vocabulary terms, virtually without cost (as well as containment queries).

At the same time, while the hierarchy is encoded, we can quickly look up terms in a subtree.

Note: As collective.taxonomy uses slash as separator, you have to monkey patch the PATH_SEPARATOR constant if you want to use ‘/’ in your terms.

Data exchange

While collective.taxonomy (this package) does make it possible to create, manage and edit taxonomies from a browser-based interface, the primary focus is to support the exchange of terms in the VDEX format:

The IMS Vocabulary Definition Exchange (VDEX) specification defines a grammar for the exchange of value lists of various classes: collections often denoted “vocabulary”.

This exchange is integrated with GenericSetup which manages imports and exports using setup profiles. It is also possible to use the controlpanel for importing and exporting VDEX files.

The package comes with integration for the Dexterity content type framework: for each taxonomy, a behavior is available that adds a choice field which pulls its vocabulary from the taxonomy. The behavior is configurable in terms of field name, title and whether it allows the selection of one or more multiple terms. You should first install dexterity and then collective.taxonomy, otherwise the behaviors for the existing taxonomies will be missing.

How does it work?

The main objective during this project has been to get a high rate of through-the-Web administration. Therefore the use of the product will not require any Python programming nor configure.zcml directives.

In the controlpanel (/@@taxonomy-settings), the user can:

1. Import taxonomies from VDEX files.

2. Export taxonomies existing to VDEX files.

3. Delete taxonomies

4. Add and delete behaviours for taxonomies

When a new behavior is created for a taxonomy, it can easily be added to the desired content types using the content type control panel, provided by Dexterity. After this is done, the taxonomy is available on add and edit forms, and it is also available for collections, if plone.app.collection is used on the site. An index is also created, so the taxonomies can easily be used for catalog queries.

See a short guide on how to use the product here.

React/Redux app to edit taxonomies

The view @@taxonomy-edit-data that allow users to edit the taxonomy data is a React/Redux app (the source code is in the javascripts directory.

Here’s a preview of this view:

The languages allowed for the taxonomies are the languages defined in portal_languages.

i18n

The app uses react-intl to handle i18n. To translate the app, add a new language in the translations directory. For example, create a es file in the translations directory that contains:

const es = {
    submitLabel: 'Enviar',
}

export default es

Then, edit translations/index.js to add the language to the translations object:

import es from './es'

const translations = {
    es,
    fr
}

You’ll have to rebuild the js bundle: npm run build

That’s it!
