Classification by categories and tags Taxonomy

Site Structure

Hierarchical and Relational

Classification of items in this website system,
and the principles of their arrangement.

I design sites as mindmaps first, with both strict hierarchy and graph-like relations.

The hierarchical structure reflected here in categories, and the relational in tags and metatags.


The category structure of the site is hierarchical, mandatory, and exclusive, meaning, that an article must have only one category, then one parent category, and up the branch to the stem of the tree. Categories are the primary organizing system of the website.



Tags are the main labels of the site, its secondary taxonomy, organized hierarchically.

Difference between Tags and Categories

Unlike categories, tags are not exclusive: one article can be labeled with multiple tags from different branches of their hierarchical tree.


These labels are the third organizing system on the site. Metatags are the part of the metadata of an article, readable by search engines. It is used for less common keywords and terms. They are used to provide a quick summary of the content and to link similar articles.

Difference between Metatags and Tags

Metatags has no hierarchy and can be added randomly, because they are not essential for the functioning of the website. Metatags are not represented in the navigation and have no dedicated descriptions.

All tags in alphabetical order (below). Main tags:

All secondary labels of the site.

Specific keywords assigned to articles in metadata according to the topics, listed alphabetically. Meta-tags are additional to categories and predefinedstructured site tags. This list includes links to articles.

Descriptive keywords - general labels, meta-tags.

Additional keywords used in metadata with meta-descriptions.
