Minutes

Reviewed Proposed Merged model.

  • Current model: http://wiki.spdx.org/index.php/File:Model-4-16-2013.png
  • Decision to merge Document and Element.
  • Decision to consider Document, Package, File, Snippet as sub classes of Elements.
  • Snippets: byte ranges as sub class of Element. Multiple elements, overlap range.
    • Not required, but permit and support, as sub case of elements.
    • File is 0..#(EOF byte).
    • snippet is only valid if it has a relationship to a file. "is part of".
