ENTERPRISE METADATA FRAMEWORK

Over the past few years, I’ve had the opportunity to discuss enterprise metadata to a wide variety of audiences and much of this conversation is captured in this “Best Practices” implementation framework.

Of course, this summary can only be a few pages long so the depth of the content here will be a tad shallow but you should be able to get the basics from the diagram and the description that follows.
