DMOZ

DMOZ (from directory.mozilla.org, an earlier domain name, stylized in lowercase in its logo) was a multilingual open-content directory of World Wide Web links. The site and community who maintained it were also known as the Open Directory Project (ODP). It was owned by AOL (now a part of Verizon Media) but constructed and maintained by a community of volunteer editors.

DMOZ used a hierarchical ontology scheme for organizing site listings. Listings on a similar topic were grouped into categories which then included smaller categories.

Personally I have DMOZ categories data files, which I use as inspiration to organize my files. It’s sort of FHS but for my local files.

Usually use Ripgrep to find required categories.

rg figlet ~/Computer/data/dmoz_category
rg Finance ~/Computer/data/dmoz_category/categories.txt|bat

Simpler alternative to DMOZ can be DuckDuckGo !Bangs.
