So it's been pointed out that a lot of this data would be effectively worthless in a public data dump, due to the fact that they're generally months out of date. In addition, XML is huge, and the Stack Overflow data dump is already very large.
Therefore, I recommend including all of the information outlined above (with Anna's clarifications and caveatsAnna's clarifications and caveats) in the Stack Exchange Data Explorer, but adding only the following to the public data dump:
- Links but excluding Related links
- Also a LinkTypes table documenting the two types of links that are included
- Account ID on Users rows
That is all. Note that I'm explicitly excluding Close and Reopen flag-votes: as Anna noted, including deleted votes gives a skewed picture of what actually happens unless flags related to deleted posts are included as well... Since most close and re-open flags are deleted, this leaves very little relevant information to include in a public, months-out-of-date dump.
It would be nice to figure out a way of including some meta-data on deleted posts, as that would enable including a much larger set of information regarding flags and reviews... However, this would be a fairly major change, and as such is out of scope for this feature request.
