GSIM v1.2 Release Note

What’s changed?
Some of main changes in GSIM v1.2 are listed by GSIM group below. Note that this list is not exhaustive, for full list of changes, see GSIM v1.2 Change Log.
For all GSIM Groups
Attribute of an object that can be inherited/derived from its relationship with other object(s) was removed. For example,
attribute “Currently Valid” of object Classification Item was removed as it can be derived from Administrative Details
attribute “History” of object Statistical Program was removed as it can be derived from self-association relation “relates to”, in conjunction with attribute “Description” which is inherited from Identifiable Artefact
All value types for attributes were made consistent. GSIM v1.2 now has following 7 value types: Boolean, ControlledVocabulary, Date, DateTime, MultilingualText, Number and String
Text in definition and explanatory text were reviewed and made consistent in terms of use of wording and vocabulary
