Analysis languages must, first and foremost, carefully describe how to extract and aggregate data. All analysis languages must be able to make a plot of an event's Missing Energy, for example. Of course, much more complex queries must also be supported, like making the plot of Missing Energy only for events with at least two jets that satisfy certain requirements. A project was started to try to collect examples in repo's of 8 such challenges ranging in complexity from the simplest to the complex. This presentation will describe the effort and the list of languages that have participated, and highlight some examples from the repositories submitted at the time of CHEP. It should be noted that while the authors are helping to coordinate the effort, the language authors and others have done the work to implement the various challenges.
