Choose the record that represents the thing
The knowledge kinds areperson, organisation, place, event, creative_work, topic and page. A person can carry roles and relationships; an organisation can be referenced from those roles. A topic is an article about a subject, not a required folder for every page. An event record is maintained knowledge about an event, distinct from a calendar occurrence. A page is ordinary authored knowledge, not a copied email thread.
{"type":"organisation","id":"33333333-3333-4333-8333-333333333333"}. This ID is fictional; use an ID returned by your own read or search. A name in prose does not establish a structured relationship.
Tasks and projects are records too, but they describe work rather than knowledge about a subject. A task can belong to a project and has one primary session. A session is the conversation history and may exist without a task; tracking a session attaches task metadata to that same conversation. Assigning a task to a project changes the task’s project reference; mentioning the project in its body does not. Tasks and projects explains their states and updates.
Paths, revisions and relationships
Use the returned ID or canonical path to read a record. Paths such aspeople/sam-fictional are addresses, not filesystem locations. The ID remains useful when titles or paths change. A full read includes the revision needed for a guarded edit; read --body returns only Markdown and is insufficient on its own for an update.
