Google Summer of Code

  • Would like some additional visibility on status and projects
    • Being discussed in business team
    • Merge tool status discussed - progress being made. Will post weekly status to mailing list


  • Nuno has a number of additional file types that he has used
  • Concern about too much detail and possible "re-inventing the wheel"
  • Discussion on Mime-type as a related standard
  • Question on how this impacts licensing
  • Agree that more detailed file types are needed for tooling, but is it needed in the resultant SPDX document?
  • Proposal: Take media type and subtype
    • Concern that we might want to express source since it is licensing related
  • Follow-up to map mime types to file types - Kate will follow-up

License Expression Language

  • Mark Gisi has a draft shared with those on the call
  • Request to merge the detailed syntax descriptions from the current spec into the proposal
  • Discussion on parenthesis
    • Not included on the list of precedence, but described later (since parenthesis is not an operator)
    • Proposal to restrict prenthesis to AND and OR
      • Concern over increasing complexity
      • Agreed that it is not a good practice
      • Mark will consider adding to the spec
    • Jack proposed an alternative way of describing license expressions - will send to Mark for consideration
