What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

SEDE has been a great tool to poke into SE data. I have seen some saved queries on it.

  • Is there a definitive [official] list of queries used for badges on there? [apparently not]
  • Is there a way to distinguish/quickly find queries used by SE itself and not user-contributed queries?

Since there is no definitive list, how many queries like this one Legendary are available from questions/answers on meta?

Re badge queries (subset of question) >
Keep in mind that some of the badges depend on information that is not available in the data dump (like sportsmanship, talkative and so on)

Kop has produced some queries split across 2 answers below. Can anyone validate that they are official/real? –  RichardTheKiwi Feb 1 '11 at 23:21

Is there a definitive [official] list of queries used for badges on there?

There is.. It's a bit out of date though.

The post is apparently too long; part 1 of 2

Is there a definitive [official] list of queries used for badges on there?

There is no official list.

Is there a way to distinguish/quickly find queries used by SE itself and not user-contributed queries?

SEDE is a dataset for users to browse—Stack Exchange uses an internal database which is not connected to SEDE. The data in SEDE dumped monthly from the database, but queries and other database information is not included (and some information, like vote records, is removed).

Keep in mind that some of the badges depend on information that is not available in the data dump (like sportsmanship, talkative and so on)

I already understood the 2nd part, but will wait for the jury on the first. SEDE is dumped monthly btw (and there appears to be commitment to continue doing so), but the Creative Commons dump is bimonthly as of this year. –  RichardTheKiwi Jan 26 '11 at 23:50
    
@waffles Understand the restrictions, but other queries? Everyone being programmers, it helps understand the exact rules from the horse's mouth. –  RichardTheKiwi Jan 27 '11 at 0:54

@cyberkiwi, I follow, I'll discuss this with Jeff, the trouble is we often tweak queries, our table names are not the same on data.se and prod, it would be quite a lot of overhead to keep a public "badge spec" up to date –  waffles Jan 27 '11 at 1:11
