XMI13 — XMI Schema Issue - representation for Associations

  • Key: XMI13-3
  • Legacy Issue Number: 5304
  • Status: open  
  • Source: Adaptive ( Mr. Pete Rivett)
  • Summary:

    Association elements are essential for referenceless associations, and can
    be very useful for creating links between existing objects for associations
    with references also (the latter should be optional controlled by a new
    They are not mentioned at all in section 4 (Schema Design Principles)
    despite appearing as Rule Set 10 in 5.2.1. and Rule Set 7 in 5.3.1.

    Also the schema and document generation rules for Association elements are
    unnecessarily heavyweight and inconsistent with the treatment of references
    on classes. For example it does not make sense for an AssociationEnd element
    to have the fixed xmi attributes; and it should be possible to dispense with
    them completely: letting an Association element refer to the linked elements
    using XML attributes. e.g. for association A with ends b and c, a link could
    be represented as follows (b1 and c1 are xmi.id's): <A b=b1 c=c1 />).
