SSAS: Reporting on Metadata

I had a comment recently on one of my older posts that I did about XMLA which asked about listing cubes in a database and whether the cube is processed and it's size.

I have posted about a number of different ways of doing this over the last few years, but I thought I would use this opportunity to consolidate a list all the various ways of doing this that I could think of. Under the covers all these techniques are ultimately issuing some sort of XMLA discover against the SSAS database and returning a result, it's just that they all use different levels and types abstractions.
