MARTE — NFP does not introduce the concept of dimension

  • Key: MARTE-116
  • Legacy Issue Number: 11871
  • Status: closed  
  • Source: THALES ( Sebastien Demathieu)
  • Summary:

    Subject: NFP does not introduce the concept of dimension. Details: NFP defines the notion of unit attached to a type but it does explicitly express the dimension related to this unit. This should be fixed to provide a comprehensive support for modeling quantities in RTES.

  • Disposition: Resolved — MARTE 1.0b2
  • Disposition Summary:

    The Dimension concept, and its possible attributes such as the base dimensions,
    is required to do dimensional analysis and verify consistency of expressions with
    quantitative NFPs.
    The concept of Dimension is not explicitly formalized in the NFP domain model
    nor in the NFP profile. However, the enumeration which gather the literals that
    are stereotyped by Unit can be already seen as a Dimension. We make this
    concept explicit here. The design of the current profile support this clarification
    with minimal changes.
    Note that SysML also includes the concept of dimension. As a first result of
    discussions between SysML and MARTE communities and a first step towards
    an alignment between both profiles in this domain, we propose to also explicitly
    support this concept.
