GSIM object for marking publishing status? "Changes from Previous Version" attribute of "Statistical Classification" object? (Q&A from GSIM e-training)

(this is Q&A from GSIM e-training GSIM Concept Group)

Question 1. Is there an information object about data that is published? The instance of published data? Some data is published from a separate database that is specialized in sharing data. It is important for us to indicate which data can be published (moved to publishing database) and which cannot. Which object will be best suited to mark it?

=> In Base Group, there are objects that we use to identify and version. Administrative Details (in Base Group) has an attribute called Administrative Status where you can indicate it. Also, in Structure Group, there are Unit Data Set (for micro data) and Dimensional Data Set (for macro data). What you can do is you use Dimensional Data Set and give it Administrative Details that you can use to indicate whether the data set is ready for release, etc.

Question 2. In "Statistical Classification" object, there is an attribute "Changes from Previous Version or Update" which direct us to "Classification Item" object and its attribute “Changes from previous version and updates”. The problem is that there is no “Changes from previous version and updates”. Should it be added?  

=> During GSIM revision, several attributes were removed as they can be covered by Base Group objects. Base Group provides features which are reusable by other objects to support functionality such as identity, versioning etc For more information, refer to GSIM Change Log.
