Categories and taxonomies

version 0.1 | Read time 1m 49s

EU Space uses controlled categories to organise content and power filters and listings. Drupal calls a controlled category set a taxonomy vocabulary and calls each option within it a term.

For example, Event type is the category set and “Conference” or “Webinar” is one of its options.

Why categories matter

Category choices affect where content appears and how visitors can find it. Select only values that genuinely describe the page.

• Listings and filters use categories to decide which pages to show.
• Service and Component can affect service-specific presentation and routing.
• Page type changes the layout available to a Structured Template.
• Access categories determine which organisation can manage a page.

Categories used by editors

Category	Used on	What it describes
Sector	News, Event, Resource, Structured Template, Image of the Day, Use Cases	The topic or area of activity, such as Agriculture, Climate, or Maritime.
Service	Editorial content	The relevant EU Space service, such as Copernicus, Galileo, EGNOS, GOVSATCOM, IRIS², or SST.
Component	Editorial content	The programme component, mission, infrastructure, or system associated with the page.
News type	News	The editorial format, such as press release, announcement, or opinion piece.
Event type	Event	The event format, such as conference, webinar, information day, or workshop.
Resource type	Resource	The kind of resource, such as document, dataset, presentation, or factsheet.
Image of the Day categories	Image of the Day	Curatorial topics used by the Image of the Day listing.
Page type	Structured Template	The page layout, such as Component, Sector, Service, Overview, or Utility.

Categories editors can manage

Editors with the appropriate permission can add, rename, and reorder options in:

• Event type
• News type
• Resource type

Other categories, including Sector, Component, Service, and Image of the Day categories, are managed at platform level. Ask a site administrator before requesting changes to them.

Add or edit an option

1. Open Categories from the administration toolbar.
2. Select Event type, News type, or Resource type.
3. Select Add term to create an option, or select Edit beside an existing option.
4. Enter a clear name and, if useful, a description.
5. If the category supports a hierarchy, select the appropriate parent.
6. Save the option. Use the drag handles to change the displayed order when necessary.

Before adding an option, check that an equivalent option does not already exist under a different spelling. Duplicate or overlapping options weaken search filters and listings.

Creating a new category set: Adding an option to an existing category is different from creating an entirely new category set. A new set affects multiple content types and filters and must be agreed with the relevant services and site administrators.

Navigation and access categories

These categories support administration rather than normal page classification:

• Menu highlights — identifies content promoted in mega-menu panels.
• User affiliation — records the organisation assigned to an editor’s account.
• User role access — records the organisation assigned to a page for access control.

Internal category names

Each category has a permanent machine name that Drupal uses internally. Editors normally work with the readable category label, but the machine name may appear in reports, exported data, support requests, or configuration discussions. It should not be renamed by editors.
