@fkaelin is this something you pick up now that you're back? :)

The public content gaps datasets are stored on https://analytics.wikimedia.org/published/datasets/knowledge_gaps/. These are CSV files, in the same format used by the knowledge gaps index tool prototype.

Where did you this link originate? I shall delete the data itself as it is outdated, and update any reference to it.

@fkaelin ok, thanks! I can access the data you linked. I found the link to the .json files at https://meta.wikimedia.org/wiki/Research:Knowledge_Gaps_Index/Measurement/Content (and I now can confirm that at least a couple of the other ones, like age, have a similar issue). Once you update the documentation on meta, please resolve this task.
