  • $\begingroup$ Define "simple dataset". I'm querying something that is a list of associations. All associations in the list have exactly the same keys. The value associated with each key has exactly the same structure, typically just one number, but sometimes a list of numbers. I'm really not doing anything fancy -- I thought. It's so frustrating when you invest many days to learn a new topic (Datasets), build something from it, and then encounter erratic behavior nobody understands. $\endgroup$ Commented Jul 8, 2017 at 16:05
  • $\begingroup$ Indeed, renormalizing fixes it. But that's the crux of the question. Is it expected practice to need to renormalize after every query? If so, why isn't that the default format of a query result? Perhaps Dataset[#//Normal] processing should be the default and there should be an option Abnormal to give you the abnormal behavior should you actually want it. $\endgroup$ Commented Jul 8, 2017 at 16:14
  • $\begingroup$ @ChrisNadovich. I did not mean 'simple' as technical term; the usual dictionary definition will do. Or the renormalized form my be considered to define simple in this case. Datasets are a work in progress. They behave a lot better in V11.1.1 than they did in V10.0. I can't say more because the dataset you use in your example was derived by querying another more complicated dataset and you give no information about that process. $\endgroup$ Commented Jul 8, 2017 at 20:03

    $\begingroup$ @ChrisNadovich. Unfortunately, I have found renormalization is often necessary, but less so in V11.1.1 than in previous versions. It is something any user of datasets should keep in mind when weirdness happens. $\endgroup$ Commented Jul 8, 2017 at 20:07

    $\begingroup$ @ChrisNadovich. Well, that's a nice sentiment and great goal the development team to have :-P Let us pray that we will live to see its achievement. $\endgroup$ Commented Jul 13, 2017 at 22:32
