[LSC] Call for votes: Optional qualifiers for !LDRAW_ORG header

[William Howard]

With 3 votes for, none against, and two (as yet) uncast, this proposal is carried.

I'll amend the header spec and announce on Lugnet later.

CHRIS: This should now give you what you need for the Library Update

  Subject: [LSC] Call for votes: Optional qualifiers for !LDRAW_ORG header


  IMPORTANT: This proposal replaces the one of 25 Aug 2007 with a very similiar title
  The only difference between the two is that the previous one only allowed for one optional qualifier, while this one allows for zero or more qualifiers
  -----------

  Background - http://five.pairlist.net/pipermail/lsc/2007-August/000915.html

  This proposal is in THREE parts.

  A "no" vote for part a) will imply "no" votes for parts b) and c)
  A "yes" vote for part a) will require seperate votes for parts b) and c)

  ------------Beginning of proposal---------- 
  a) To add optional qualifiers to the !LDRAW_ORG meta-command.
  The new syntax for this meta-command becomes
      0 !LDRAW_ORG Part|Subpart|Primitive|48_Primitive|Shortcut (qualifier (... qualifier)) UPDATE YYYY-RR
  (see http://www.ldraw.org/Article398.html).  
  The  "Unofficial_" extension of Appendix I is still valid.
  There may be zero or more qualifiers per file.


  b) To define an "Alias" qualifier for the !LDRAW_ORG meta-command.  
  The purpose of the Alias qualifier is to identify a part which is visually identical to another (often caused by LEGO using two differnet numbers, one for opaque and one for trans versions of the same part e.g. http://www.ldraw.org/cgi-bin/ptdetail.cgi?s=32061, but more recently, there have also been new part numbers for well-established parts - such as brick 2x6).
  An alias file will typically, but not necessarily, contain only one sub-file reference (line type 1) entry
  A file with an Alias type qualifier must not refer to a file that itself has an Alias qualifier.


  c) To define a "Physical_Colour" qualifier for the !LDRAW_ORG meta-command.
  The purpose of the Physical_Colour qualifier is to identify a part which is encoded as a specific colour of a part e.g. http://www.ldraw.org/cgi-bin/ptdetail.cgi?s=73311

  An alias file will typically, but not necessarily, contain only one sub-file reference (line type 1) entry, where the entry has a specific colour value and not colour 16
  ---------------End of proposal--------------
