Notes and knowledge
16 notes and knowledge listings with a free or open edition: 12 with a named customization surface, 16 with an interface an agent can drive.
Adaptable means the source is public and there is a named surface to change. Operable means an agent can drive it through an interface; the reach list on each page says which jobs. One entry in the directory, describing one piece of software in one form factor. The unit of the directory.
