osu!mania data

I extracted osu!mania data from the osu! website for data analytics.

Most information about the data can be found in the following.

BEATMAPS

Only ranked & loved beatmaps are grabbed.

There are 3 entries per unique ranked beatmap.

  • Half Time
  • No Mod
  • Double Time

You can tell them apart in the mods column.

These entries only vary in the difficultyrating from what I know.

"approved"             : "1",                   // 4 = loved, 3 = qualified, 2 = approved, 1 = ranked, 0 = pending, -1 = WIP, -2 = graveyard
"submit_date"          : "2013-05-15 11:32:26", // date submitted, in UTC
"approved_date"        : "2013-07-06 08:54:46", // date ranked, in UTC

"audio_unavailable"    : "0"                    // If the audio for this beatmap is unavailable (DMCA takedown, etc.)

Columns, "max_combo", "diff_aim", "diff_speed" may be NULL.

SCORES

Only ranked & loved beatmaps are grabbed.

Only the top 100 scores are grabbed, hence note the following:

  • The top 100 may not be all No Mod
  • enabled_mods define the mods used
  • Loved scores do not have pp
"score_id"         : "7654321",
"score"            : "1234567",
"username"         : "User name",
"count300"         : "300",
"count100"         : "50",
"count50"          : "10",
"countmiss"        : "1",
"maxcombo"         : "421",
"countkatu"        : "10",
"countgeki"        : "50",
"perfect"          : "0",          // 1 = maximum combo of map reached, 0 otherwise
"enabled_mods"     : "76",         // bitwise flag representation of mods used. see reference
"user_id"          : "1",
"date"             : "2013-06-22 9:11:16", // in UTC
"rank"             : "SH",
"pp"               : "1.3019",        //Float value , 4 decimals
"replay_available" : "1"              // 1 = replay is available for download, 0 = replay is unavailable

SAMPLING (2500)

In every data set, there's a sampleset for 2500 randomly selected.

Hence:

  • SCORES_2500 may not have beatmap_id that match BEATMAPS_2500.
  • Entries of BEATMAPS_2500 may not include all 3 variations.
  • Top 100 of a single beatmap is never guaranteed.
