About

If taxonomies are defined as documents in the /sites subtree of the Neos ContentRepository, things tend to get complicated:

If the meaning of an item is determined by its position in a hierarchy, it is complicated to add more than one relation or relations for different contexts.
Mixing Taxonomies (meaning) with content (presentation) leads to a complicated structure that often is hard to comprehend for editors.
It is hard to share taxonomies across multiple sites.
It is hard to ensure taxonomies exist in all needed dimensions since this also affects the site structure.
Limiting read and write access to taxonomies inside sites is possible but not trivial.

Sitegeist.Taxonomies store vocabularies and taxonomies as nodes outside of the /sites hierarchy in the content repository. This way, the meaning of the taxonomy relations can be expressed better, taxonomies can be used across multiple sites and the taxonomy documents can be defined without interfering with the taxonomy meaning.

It also provides a separate backend module for managing vocabularies and taxonomies.

Installation

Sitegeist.Taxonomy is available via packagist composer require sitegeist/taxonomy. We use semantic-versioning, so every breaking change will increase the major version number.

Storing vocabularies and taxonomies in the ContentRepository

Sitegeist.Taxonomy defines three basic node types:

Sitegeist.Taxonomy:Root - The root node at the path /taxonomies, allows only vocabulary nodes as children
Sitegeist.Taxonomy:Vocabulary - The root of a hierarchy of meaning, allows only taxonomies nodes as children
Sitegeist.Taxonomy:Taxonomy - An item in the hierarchy that represents a specific meaning allows only taxonomy nodes as children

If you have to enforce the existence of a specific vocabulary or taxonomy, you can use a derived node type:

    Vendor.Site:Taxonomy.Root:
      superTypes:
        Sitegeist.Taxonomy:Root: TRUE
      childNodes:
        animals:
          type: 'Sitegeist.Taxonomy:Vocabulary'

And configure the taxonomy package to use this root node type instead of the default:

    Sitegeist:
      Taxonomy:
        contentRepository:
          rootNodeType: 'Vendor.Site:Taxonomy.Root'
          vocabularyNodeType: 'Sitegeist.Taxonomy:Vocabulary'
          taxonomyNodeType: 'Sitegeist.Taxonomy:Taxonomy'

Referencing taxonomies

Since taxonomies are nodes, they are simply referenced via reference or references properties:

    taxonomyReferences:
      type: references
      ui:
        label: 'Taxonomy References'
        inspector:
          group: taxonomy
          editorOptions:
            nodeTypes: ['Sitegeist.Taxonomy:Taxonomy']
            startingPoint: '/taxonomies'
            placeholder: 'assign Taxonomies'

If you want to limit the selectable taxons to a vocabulary or even a taxonomy, then you can configure a more specific startingPoint:

    taxonomyReferences:
      ui:
        inspector:
          editorOptions:
            startingPoint: '/taxonomies/animals/mammals'

Content-Dimensions

Vocabularies and Taxonomies will always be created in all base dimensions. This way, it is ensured that they can always be referenced. The title and description of a taxons and vocabularies can be translated as is required for the project.

CLI Commands

The taxonomy package includes some CLI commands for managing the taxonomies.

taxonomy:list List all taxonomy vocabularies
taxonomy:import Import taxonomy content, expects filename + vocabulary-name (with globbing)
taxonomy:export Export taxonomy content, expects filename + vocabulary-name (with globbing)
taxonomy:prune Prune taxonomy content, expects vocabulary-name (with globbing)

Privileges

Sitegeist.Taxonomy brings the following privilege targets to allow you to restrict read access, management and editing of taxonomies:

Sitegeist.Taxonomy:Module.Show Show the backend Module and explore the existing taxonomies by default granted to Editors.
Sitegeist.Taxonomy:Module.ManageVocabularyActions Add, edit and delete vocabularies. By default granted to Administrators.
Sitegeist.Taxonomy:Module.ManageTaxonomyActions Add, edit and delete taxons. By default granted to Administrators.

Reading and referencing taxonomies from other nodes is currently not limited.

Extensibility

Packages can add additional fields to the forms of taxonomies and vocabularies. To do this the following steps are required.

Extend the NodeTypes Sitegeist.Taxonomy:Taxonomy or Sitegeist.Taxonomy:Vocabulary in your package.
Add tha path to your additional Root.fusion to the Setting in path Sitegeist.Taxonomy.backendModule.additionalFusionIncludePathes.
In the fusion code define each field as prototype that accepts the props name plus taxon & defaultTaxon resp. vocabulary & defaultVocabulary.
Register addtional prototypesNames by adding them to the Settings Sitegeist.Taxonomy.backendModule.additionalVocabularyFieldPrototypes or Sitegeist.Taxonomy.backendModule.additionalTaxonomyFieldPrototypes
