Turns out using an isosec identifier is a problem because there is no indication of what that node is about, nor is there any promise that the time of the isosec has any relevance. Instead, I’ll be forcing myself to create actual names that match the titles and deprecating or deleting or redirecting when that title changes. This is what I did for several years before the latest iteration of my zet design. I felt having the names free to change was best.
Strictly speaking, there is nothing in the KEG specification that prevents others from using isosec if they wish.
