Collection – This could be as simple as making a list. The most common directory in use is the Contacts list on your smartphone (people and phone numbers, sorted in alphabetical order)
Curation – Seeking to list the “best of” resources for a topic
Examples
Feed Handbook (by Andy Sylvester) – Information on feeds of many types (RSS/Atom/etc)
Radio Userland Resource Directory (by Andy Sylvester) – created in 2007! (have to hover in front of the entry to see the link, need to update this sometime…)
Bob Dylan Bibliography (by Ron Chester) – created in 1996!
Indieseek XYZ (by Brad Enslen) – A human edited Indieweb directory
href.cool (by Kicks Condor) – in the style of the old DMOZ and Yahoo directories
Tools
Web page – make a ordered list or an unordered list and – voila! – a directory is born
Hugo – static site generator, used for the Feed Handbook above
OPML – XML file format used for subscription lists for podcast players
OPML Editor (for editing OPML files)
Little Outliner 2 (for editing OPML files)
WordPress – use of categories could create a directory structure, also there are many plugins to support creating directory websites (like Yelp, etc.) or simple directories
