Ember Ghost has a single, powerful organisational taxonomy, called tags.
It doesn't matter whether you want to call them categories, tags, boxes, or anything else. You can think of tags a lot like Gmail labels. By tagging posts with one or more keyword, you can organise articles into buckets of related content.
When you write a post, you can assign tags to help differentiate between categories of content. For example, you might tag some posts with
News and other posts with
Cycling, which would create two distinct categories of content listed on
If you tag a post with both
Cycling - then it appears in both sections.
Tag archives are like dedicated home-pages for each category of content that you have. They have their own pages and hopefully soon will support their own cover images and meta data.
The primary tag
At the top of every post there is a tiny bit of YAML, and the tags key is an array of tags. The first tag in the list is always given the most importance, and some themes will only display the primary tag (the first tag in the list) by default. So you can add the most important tag which you want to show up in your theme, but also add a bunch of related tags which are less important.
tags: - news - cycling - bart-stevens - extreme-sports
In this example, News is the primary tag which will be displayed by the theme, but the post will also still receive all the other tags, and show up in their respective archives.
