Tim, any chance of you posting your code? Or at least the metadata interrogator class?

Thanks!!

Oh - I meant to add in the article that by far the best book on this subject is ".NET and COM - The Complete Interoperability Guide" - as per the following:

Oh trust me, you'll be delighted by Longhorn :-)

WinFS has a much stronger understanding of the underlying metadata and will be able to do filtering, grouping and complex queries with a sub-second response. You can expect to see all these properties properly managed and surfaced via an XML schema. Check out the promotion / demotion stuff in this post:

I've endeavoured to do the same thing on a number of occassions trying to get my media collection metadata into a DB ..

I've mused a couple of times how nice it would be if Media Player had the option to store media metadata in MSDE -- or even better, with the advent of longhorn, use WinFS..

I'm glad that someone at MS sees the value in this ;)
