Kim, we recently upgraded to 10.2.2 so we're still able to create SDE views. You mentioned two years ago that the problem of metadata for views was something that ESRI planned to address before the admin commands were retired. Has it been addressed at 10.3, or if not, at 10.4?
ArcGIS metadata is stored in the geodatabase system tables, so you cannot store ArcGIS metadata for objects that are not registered with ArcSDE or the geodatabase. The views created through ArcGIS Desktop are database views and are not registered with ArcSDE or the geodatabase and, therefore, ArcGIS metadata cannot be stored for them.
We realize this is a limitation that needs to be addressed before the admin commands are retired. At present, though, the only way to store ArcGIS metadata for a view is to create it with the sdetable command as you described.
