This page shows the differences between the current clean version model with ETSI IFA011 v2.4.3 .and other proposed changes:
- Verified against IFA011 v2.4.3. Also verified against v2.4.3 of the info model.
- Added "Attribute Type" column to indicate whether the class attribute is an "attribute" or member end of an "association". Without this information it is difficult to create a class diagram. We might want to consider also for those "Attribute Types" that are associations to put whether there is shared or composite aggregation, or no aggregation at all. Not added to current proposal.
- Changed attribute Applied Stereotypes to OpenModelAttributerepresent the actual stereotypes being applied, and not just a property of a stereotype.
- Added class definitions and applied stereotypes
- Proposal to define actual enums and not use the general term "Enum"
- Proposal to remove incorrect usage of valueRange in OpenModelAttribute stereotype
