[This list is incomplete]

Formatted datasets:
Each datasets follow strictly the same formats (CSV and compact), detailed in the next sections. Compact format enables datasets usage in size-constrained environments (e.g. in browsers).
Note: Use raw files to use data not included in current formats.

CSV format description

• First line: header
• Column 1: User's name
• Column 2: Typed text
• Column 3 to N: User meta-data
• Column N+2k+1: Press to Release durations [=A->a] (integer in ms)
• Column N+2k+2: Press to Press durations with next typed character [=A->B] (integers in ms)

Example:
UserID Text gender A->a A->B B->b
1 ab M 1 2 3
1 ab M 1 2 3
2 ab F 1 2 3

Compact format description
The formatted datasets follow this format (in UTF-16):

• The typed text
• 0x0000
• Users meta-data array (JSON)
• 0x0000
• For each users its number of entries (2-bytes integer)
• 0x0000
• For each users:
  • For each user's entries:
    • For each typed characters:
      • Press to Release durations [=A->a] (2-bytes integers in ms)
      • Press to Press durations with next typed character [=A->B] (2-bytes integers in ms)

Example:
ab # typed text.
0x0000 # Beginning of users meta-data.
[{"gender":"M"},{"gender":"F"}] # 2 users, user 1 is male, user 2 is female.
0x0000 # Beginning of users number of entries.
0x0002 # 2 entries for user 1.
0x0001 # 1 entry for user 2.
0x0000 # Beginning of users entries.
0x0001 0x0002 0x0003 # User 1 first entry.
0x0001 0x0002 0x0003 # User 1 second entry.
0x0001 0x0002 0x0003 # User 2 first entry.
# 0x0001 => A->a = Release(A) - Press(A) = 1ms
# 0x0002 => A->B = Press(B) - Press(A) = 2ms
# 0x0003 => B->b = Release(B) - Press(B) = 3ms
