Structured list of title holders

[hyperpape]

This is something I've wondered about off and on. Is there any publicly available list of title holders available? By structured, I mean json, xml, csv or somesuch. Actually, even well structured HTML would not be so bad, since it's not too hard to parse into one of the other formats.

DO you want current title holders or a complete historical list? Some of the information must be on Sensei's Library.

The software I use to maintain my SGF collection includes lists of title holders,
and a database of player ranks, so that the BR and WR fields can be checked.
Can you use something like

Code: Select all

# the first five are really the ACOM Cup
agontable = [
        ["O Rissei", "1994-09-17", "1995-09-09"],               # 1
        ["Kato Masao", "1995-09-09", "1997-09-28"],             # 2-3
        ["Yoda Norimoto", "1997-09-28", "1998-09-26"],          # 4
        ["Kobayashi Satoru", "1998-09-26", "1999-10-10"],       # 5
        ["Kobayashi Koichi", "1999-10-10", "2000-10-08"],       # 6
        ["Cho Sonjin", "2000-10-08", "2002-10-13"],             # 7-8
        ["Cho Chikun", "2002-10-13", "2003-10-13"],             # 9
        ["Kato Masao", "2003-10-13", "2004-10-09"],             # 10
        ["Hane Naoki", "2004-10-09", "2005-10-08"],             # 11
        ["Iyama Yuta", "2005-10-08", "2006-10-07"],             # 12
        ["Cho U", "2006-10-07", "2009-10-17"],                  # 13-15
        ["Hane Naoki", "2009-10-17", "2010-10-02"],             # 16
        ["Yamashita Keigo", "2010-10-02", "2011-10-01"],        # 17
        ["Iyama Yuta", "2011-10-01", "2012-10-06"],             # 18
        ["Cho U", "2012-10-06", "2013-10-05"],                  # 19
        ["Murakawa Daisuke", "2013-10-05", "2014-10-18"],       # 20
        ["Iyama Yuta", "2014-10-18", "2015-99-99"],             # 21-22
]
...

Historical. Senseis would be of some value, though it's quite limited for some events, and it would be a little bit of a pain to process.

aeb: what database is that? Also, I'm guessing the dates are when the player gained then lost the title?

At least the history of big titles are listed on http://senseis.xmp.net/?BigTitle

Yes. It is a fragment of supporting software that intends to automatically check data like

Code: Select all

2014-10-08  33rd Female Honinbo Title  1  227  B+R  Fujisawa Rina (2p, Aizu Cup)  Mukai Chiaki (5p, Female Honinbo)  FHon-2014-1.sgf

(If one collects games from the net, then all conceivable mistakes occur. Wrong date, wrong event, wrong players, wrong moves. That means that to get a somewhat reliable collection, everything has to be checked. Player ranks are in http://www.cwi.nl/~aeb/go/misc/progression.html, player titles in the above-mentioned tables.)

Example of where Senseis falls a little short: http://senseis.xmp.net/?Siptan. No years, non-standard format.

I did a little work filling in gaps in some of the senseis articles a few years ago.
