Type(s): Issue

Subject Identifiers (1)

Internal Occurrences (3)

  • Description
    • The XTM DTD contains a number of implicit constraints, such as that an addressable subject may not be used as a theme or a type. Should these constraints be mirrored in the SAM?
  • Opinion
    • we should evaluate them and not be afraid to NOT model them in the same. i.e. constraints such as 'A Topic that *is* a resource cannot be a used as a scoping topic.'. I'm actually torn on this one. It seems like we'd be adding some sensible 'real-world' usage constraints. But this also prohibits people from doing cool funky things we havent thought of yet. - Scope: Graham Moore
  • Resolution
    • The SAM should not necessarily attempt to mirror the constraints implied by the XTM 1.0 DTD.
