DTV13 — spec should provide a simple library of datatypes for use in UML and data modeling

  • Key: DTV13-11
  • Legacy Issue Number: 17349
  • Status: closed  
  • Source: Adaptive ( Mr. Pete Rivett)
  • Summary:

    This spec should provide a simple library of datatypes for use in UML and data modeling. This is present in many physical data standards (e.g. SQL/JDBC, XML Schema) but is lacking in OMG for platform independent modeling. That would include types such as:

    • Date
    • DateTime
    • TimeStamp
    • Duration

  • Disposition: Resolved — DTV 1.3
  • Disposition Summary:

    Revise clause 18 to define datatypes

    The principal DTV concepts that will be represented in software are time interval, time coordinate, duration value, occurrence, and various properties and relationships among time intervals and occurrences. The latter two are Classes and any Class implementation will be a view that incorporates only the desired associations. Time coordinate and duration value will have datatype representations. The representations of these concepts are specified in Clause 18. The text of Clause 18 is modified to describe them as 'datatypes'. In addition, the text of Clause 18 is reorganized and enhanced to reflect the 'datatype' view of representation.

    In the discussion of this issue, it was noted that the Internet Time representations (described in Clause 14) are omitted from Clause 18. The corresponding text is added to clause 18 as an alternative form.
