e.g.

• lang=en (as per #767 )
• aspect= author (we essentially have that in the current URL scheme for aspects, so maybe not necessary)
• panel = recentpublications (or a more persistent ID, as per #1113 )
• parameter = LIMIT1 (we'd have to find a way to refer to specific LIMITs or similar calls in a SPARQL query as variables from JavaScript or Python)
• parametervalue = 500

If we had that and persistent IDs for individual panels, then that would provide users (or us, perhaps in some selenium-y way) with a mechanism to retry a failing panel with other parameters.
