Subject: SGF - request for final comments


Hello folks,

I'm planning to bring the discussion to an end, i.e.
I want to upload one more version (V10) and then make
it the official FF[4] SGF standard.

So email your final comments to sgf_std!
Note: please don't bring up topics that we've discussed AND solved
in the past.

What has to be changed for version 10?

- remove BO & WO
  There are so many different byo-yomi systems out there that
  these properties are no good at all

- I intend to keep SQ (Anders supposed using SC)

- Should we allow text in between game-trees?
  David misunderstood me last time, so let me make it more clear:
  An SGF file consists of exactly ONE collection which consists
  of one or more game-trees.
  The standard allows text in front of the collection.
  I want to add allowing text after the collection plus text
  in between game-trees which are direct decents of the collection,
  i.e. in between games but not in between variations.
  Why?
  Because applications have to skip text there anyway to find
  out if another game-tree follows or if the end of file is
  reached. Applications may even use the same FindTreeStart()
  function they use for finding the start of the collection.
  Otherwise apps would have to complain about every signature
  they find at the end of a file sent via email.
  Opinions?

- I want to add DS (Diagram spec) and modify FG for applications which
  are used to print diagrams.
  FG: current value: none
      should have: (composition of number : simpletext)|none
      Where number contains some flags (any ideas?)
      and simpletext contains a title for the diagram.
  DS: value: number
      0 ... use move numbers
      1 ... use 'modulo 100' numbers as known from books/mags
      2 ... don't number moves
      any DS setting is valid until another DS value is set or
      another figure (FG) starts - DS is only valid for the
      current variation.
  Opinions?
 

That's all what comes to my mind right now.

Comments, criticism etc. welcome
