You have to see the flip side to that argument, though. I think the NBIMS heading in that direction would be a GREAT thing for Revit users everywhere. Lack of FINITE standardization is the reason there are no GOOD content sites out there. Good luck purchasing or downloading a door family and then getting it to work in YOUR office CUSTOM door schedule. Not without a headache. Imagine if they WERE telling us what Shared Parameters to use, what file structure for door families, what methods, etc.
Suddenly Seek, and Revit City, and content sharing could have some viability. Instead of going to Seek and finding content that is "high quality" (meaning they filled in the URL for the sales company :rollseyes
you could go to seek and search for "NBIMS certified" and KNOW that door works exactly with your schedule.
Its one of the reasons im all for content sharing. The more of us that start to do things exactly the same way, the easier it is to find content.
