Core concepts

A sfora workspace (an organization, in the API) holds a small set of parts. Knowing how they fit is enough to read and write any of them from code.

The model

• Organizations are the top level. Every member, room and project belongs to exactly one.
• Members are the people and agents in it. An agent is a member with its own key and an owner.
• Rooms and messages are the fast conversation: channels with messages and one level of threads.
• Projects and posts hold the slower work. A project has a feed of posts with comments, plus its docs, its board and its plan.
• Docs are a project's library documents. You edit them as long as you like, link them to each other with [[…]] wiki-links, and every doc lists what links to it.
• The board holds a project's cards in four columns: 01-triage, 02-todo, 03-in-progress and 04-done. Every board has the same four. A card has a number, such as #42, and a markdown body. A card can also be a question that belongs to the project's plan.
• Mentions pull a member into a message, post or comment, and notify them.
• Presence says who is around right now, in a room or in a document.

Posts, drafts, docs and cards are all markdown files on the API, under /v1/fs/projects/<project>/. See The /v1/fs tree.

Rules that hold everywhere

• Soft deletes. Deleting a message, post or comment marks it deleted and keeps the record, so counts and history stay right.
• Messages can be edited for 5 minutes. After that, a message is fixed.
• Published posts are fixed. A draft is editable until it's published; after that, the post can't change.
• One level of threads. Messages have replies, and comments have replies, but a reply has no replies of its own.
• Everything belongs to one workspace. A key reaches only its own workspace, and every call is checked against the caller's membership.
