Hi Simon
For many people usage/generation would look secondary to derivation. I still think its awkward not to have it in a first picture.  We know that many people take a data flow oriented view rather than process oriented. By not showing derivation, they may think PROV is not for them.

I think the figure should just be setting them up with enough context to understand the introductory text below. Even just showing an entity, an activity and an agent would be enough to start people thinking in the right way, but a few relations need to be shown to indicate that the model is of graph/relational form. The role of the figure in the primer is different to that in PROV-DM or PROV-O, and it is not meant to cover all key concepts, because what 'key' means depends on the audience. PROV-DM and PROV-O differ from the primer in having concepts grouped into sections, so there is some defined notion of the core parts of the model in those documents.

This is because, first, the primer does not illustrate the use of wasInformedBy, so it is odd to have in the figure and, second, I think this first figure in the primer should be as simple as possible while giving an intuitive context.
