Liaising OCL examplesBernd
  • Liaising OCL usage examples to MEF, SG15, ...
    • Bernd gave an overview on the example of learning and using OCL (Object Constraint Language) in UML modeling.
    • In the example, the cardinality is 2. Noted that OCL doesn't support infinite cardinality (i.e., *).
    • As shown in the example, the iteration of the loop has to be explicity listed. When the cardinality is large, then the list will be long.
    • Noted that the constraint is not just applicable to creation. It can also be applicable when trying to change the value of the attribute
    • MEF has been working on using OCL
    • Should mention about using OCL to describe the pattern of attribute
    • Agreed to liaise to: MEF, SG15 Q14, OASIS (they look at constraint-base) of TOSCA, ONAP,
    • Should go into the UML modeling guidelines document.
    • Action item - Bernd: draft the LS text for the group to review.
  • Finalize Packet examples for TR-512.A.6 v1.4 publication
    • Editor instruction from the discussion:
      • Enhance the text under Figure 4-1: more flexibility on case 1
      • On Fig. 4-2 (b), describe the distinction of the tag types, some are layers and have termination (S-tag and B-tag), some not (I-Tag). And thus the difference as shown in the diagrams.
    • Fig. 4-3, LAG: The LAG model has not been agreed yet. See TR-512.4 v1.3.1 in section 4, Figure 4-38 in the inverse multipleing example on LAG,
    • Will have more discussion on Thursday OIMT call.
  • Summary work on TR-512.A.5. Not discussed.
 IEEE 802.1Qcp DMBernd/Kam
