Which of these are equivalent (more or less) to the Atom/RSS notions<br>
of a modification time stamp? Which are not? In combination with an id<br>
(already recommended in GeoJSON) that kind of timestamp lets you sync<br>
features between systems. With this in mind, the "adding media" bullet<br>
suggests that some of us are looking for GeoJSON to expand its domain<br>
to cover that of feeds. Is my assessment right?<br>
