My equivalent, as best as I can tell, is:

• Permanent notes (atomic, linked concepts) = Notions
• Temporary notes (half-formed thoughts, links, snippets, etc.) = Notes
• Temporary notes initially, which later become permanent notes = Ideas (see later comment about why)
• Admin notes (projects, tasks, meetings, etc.) = Work notes

Similar to how I've come to think of my "admin" or "operational" notes. They're instrumental in that they serve a purpose that is usually about moving some project forward.
