Category Tree Level 1 is the list of the permanent top-level categories. These top-level categories have been agreed to in G2G discussions and through the collaborative efforts of the Categorization_Project. [1]

Contents

Overview

The purpose of this page is to be a G2G-linked reference blueprint of the agreed top-level category tree to be maintained. [2] Categories in this list should not be moved from their top-level position in the category tree, unless by consensus through the project and/or G2G discussions. Also, no new categories should be created or moved into the top level without discussion consensus.

Top-Level Explained

The top-level categories are simply the small group of the most general "parent" categories. They are each populated by other categories, which are more narrow in focus, and which are related to each other. Those "child" categories are also known as sub-categories. In this way, each category has a parent category. This structure makes it possible to easily navigate from any any categorized page, through successive layers of categories, to reach a more general or ultimate top-level parent category.

Another way to think of the top level of the category tree might be as the collection of the root categories. In genealogy, a root ancestor has many successive layers of descendants. In the same way, a root category has many successive layers of related sub-categories, which become more and more narrow in focus the farther away they are from the root.

How To Start a G2G Discussion

G2G discussions about any major changes to any of these top-level categories can be started from this page. To do so, follow these steps:

  1. Start a G2G discussion with this link
  2. in the box for category select "Policy and Style"
  3. in the box for WikiTree ID/URL put Space:Category_Tree_Level_1
  4. in the box for Surnames and project tags put categorization

If the category you wish to discuss already exists and is on this page in the lists below, first check to see if it already has a linked G2G discussion about it. Read those G2G discussions to see if they address your question.

But if the category is not listed on this page, then try to locate it on the lower level pages (under construction soon) for discussion from there. Please do not create any new category simply for the purpose of opening a discussion about it.


Top Level Template

All top-level and other high level categories should contain the template, {{Top_Level}} in the upper part of the category page.[3] This template displays the following box:

This is a high level category. Please do not add individual profiles. Add profiles to the narrowest category possible. See How to Categorize.

This means that a top-level category (and also nearby lower level categories) should primarily be for grouping together the related lower subcategories, and should NOT contain any person profiles at all. Instead, those person profiles should only be categorized at a lower, narrower level. [4]

However, in some cases some free-space pages might only be best categorized at the top level (For example, this page).

Other Languages

Parallel or mirrored category trees are being developed in other major languages. [5] Those category trees should be maintained to follow the same categorization pattern as the English category tree. [6] Each other language tree does not need to be as complete as the English tree, but where other language categories exist, they should be sub-categorized the same as the English tree, whenever possible. Differences between the language category trees should be resolved through discussion as needed.

Category Definitions

Each top level category should have a small bit of definition, appropriate links, and/or a template to describe what it is for or to direct viewers to related alternative categories. But the amount of description, graphics, etc. should be limited within reason, so as not to detract from its main purpose as a category listing of related narrower sub-categories.

If much more lengthy detail is desired (such as the history of a place), then create a free-space page on the topic instead, and categorize it!

Category Style

A top-level category should follow the style guidelines, so avoid using CSS and other non-wiki code.[7]

List of Top-Level Categories

The list below are the agreed top-level categories. They appear under Category:Categories. Note that Category:Categories is the only category which is not a member of any other category, by definition, and should never be added as a sub-category of any other category.[8] Instead, it is the top-of-the-category tree. [6]

This page is new, so be aware that notes appear next to some categories which are questionable, or are under discussion now or soon, because they were moved or created recently, without any thorough discussion. So those noted categories are subject to removal or change.

Otherwise, the top-level categories should always be the ones outlined here below:

List of top-Level Categories - #9 (Immigration) needs to be updated to show the current name of Migration (revised 18 May 2018 through discussion in G2G.
posted by Steve Harris
I'm trying to understand the larger concept of categories and started at the top with the permanent top-level categories which is listed on this page.

In the category structure, there is still 24 subcats but they don't correspond exactly to this list. Either the list should be updated or someone moved or renamed categories that should not have been moved or edited.
