Markus, do you have access to the corresponding HTTP request logs? The fields there might be helpful (although I might be overtly optimistic about it)
Yes, we can access all logs. For bot-based queries, this should be very helpful indeed. I can still think of several cases where this won't help much:
* People writing a quick Python (or whatever) script to run thousands of queries, without setting a meaningful user agent. * Web applications like Reasonator or SQID that cause the client to run SPARQL queries when viewing a page (in this case, the user agent that gets logged is the user's browser).
But, yes, we will definitely look at all signals that we can get from the data.
Best, Markus

This graph uses both (one to get all countries, the other is to get the list of disasters) https://www.mediawiki.org/wiki/Extension:Graph/Demo/Sparql/Largest_disasters * There has been some discussion to allow direct WDQS querying from maps too - e.g. to draw points of interest based on Wikidata (very easy to implement, but we should be careful to cache it properly) Since all these queries are called from either nodejs or our javascript, we could attach extra headers, like X-Analytics, which is already handled by Varnish. Also, NodeJS queries could set the user agent string.

Having a way to tell apart bots and tools from "organic" queries would already be great. We are mainly looking for something that will help us to understand sudden peaks of activity. For this, it might be enough to have a short signature (a URL could be given, but a tool name with a version would also be fine). This is somewhat like the "user agent" field in HTTP. But you are right that some formatting convention may help further here. How about this: #TOOL:<any user agent information that you like to share> Then one could look for comments of this form without knowing all the tools upfront. Of course, this is just a hint in any case, since one could always use the same comment in any manually written query.
