Template talk:OEIS Wiki Knowledge Base

This is an awful piece of work! Congratulations, I'm almost speechless from admiration about the discipline it must have required to build! Some thoughts, nonetheless:

• it would be nice to have a mechanism to "fold" (collapse) and "unfold" subsections. Indeed, for well detailed (sub-structured) categories it is nearly impossible to get a global view
• it would be nice to have a mechanism which builds this table automatically from the structure of the categories as used on the wiki. Clearly, that structure is not rigid enough (one category can be subcategory of several other categories), but one could imagine a special mechanism to make this unique (e.g. consider for this purpose only the very first category ([ [ Category: xxx ] ] tag) listed in a given category. — M.

The thing is, it's nearly impossible to manually keep "Overview pages" in sync with the actual category hierarchies. Plus, the "Overview pages" just get way too big... so they are very much outdated with respect to the current category hierarchies, making those "Overview pages" essentially moot... unfortunately. On OEIS Wiki Overview (top level) you can see links to more "Overview pages"

OEIS Wiki Knowledge Base Overview

Mathematics Overview

Sequences Overview

Integer Sequences Overview

but they are also very much outdated with respect to the current category hierarchies... (I'm pretty sure that they eventually will all be deleted, especially if we use one of the MediaWiki extensions that I mention hereafter...)

What we would need is the following MediaWiki extensions to be installed (where the Administrators have to ponder the performance and security issues pertaining to those extensions...)

Extension:DynamicPageList—MediaWiki.org.

Extension:TreeAndMenu—MediaWiki.org. (creates dynamic dropdown and folder tree menus, thus requires JavaScript to be enabled with the browser)

We might also want to consider

Extension:Semantic MediaWiki—MediaWiki.org.

Also, the categories hierarchy is a network (should be a DAG), not a tree, and all the parent categories currently have equal status, the first category is not a primary parent category and the remaining (after the first) parent categories are not secondary parent categories.
