Liz is writing an article about her work She would like to get Jean-Luc's opinion,
so she sends him a link to the article stored on her personal datastore
he prefers to use an academic view to read her article
He uses the article's interactive components to understand her work better
Then signs in to his own store
And annotates a section with a suggestion, (this is saved directly to his store)
Liz sees Jean-Luc's comment and signs in
makes the change he suggests,
and saves directly back to her store
