I think the figuredincluded at the top of the file may work better in the "API Examples" section of the file.

@Emmavt which figures do you mean? The Google example? I think the reason they are there is to give participants a quick overview of how RESTful APIs can be read/understood. Did this end up being confusing?

Sorry - my initial text was absolutely not clear enough. I meant the workflow referencing the UC library resources for accessing remote data.
