Publishing Tabular Models to SSAS

This is a follow-up from my blog post last month here on SQL Server Pro about utilizing common traditional reporting tools like Excel and Report Builder with the new SQL Server 2012 Tabular models (http://www.sqlmag.com/blog/sql-server-bi-blog-17/business-intelligence/report-builder-tabular-model-databases-142942) . I've received a few notes about some confusion concerning the processes to publish PowerPivot-generated models and the Visual Studio SSDT-generated models to SSAS 2012. I was sent a question pointing to the currently empty Books on Line entry on the "Restore from PowerPivot" technique that I was advocating: http://msdn.microsoft.com/en-us/library/hh230822.aspx.
