I'm creating a new Drupal theme for news web sites, which needs some fields to be added to the Article content type to work. For example, the theme will change the header image into something science-related when the user is viewing an article tagged with the term "Science" of a taxonomy called "Section".
I have set up the "Section" vocabulary and added it as a field to my Article content type manually, but the theme I'm making should be "shippable" to end customers, meaning that someone should be able to download it and install it without manually creating taxonomies and fields.
The theme must in some way notify the user that it depends on the Taxonomies module, and, when installed, the theme must create the relevant taxonomies and add fields for it to the "Article" content type.
What is the best way to accomplish this in Drupal 7? The only way I can think of is to create a specific "installer module" for my theme, that officially depends on Taxonomies and are able to add the right fields to Article etc, but there must be a more robust and "standard" way to accomplish this?
