I'm in the process of choosing a framework for my flex development, and one of the questions that was asked about a framework was "is this a framework or a micro-architecture"?

Can someone clarify what's the difference?

What exactly is a framework, and when can we start calling what we have a framework? I work with FlexBuilder3 (now called FlashBuilder4) and have a lot of standard things that I do for almost all projects, and components that I created for easy re-use. Some are very very small, but the benefit of a 1-liner has been immense for me instead of repeating the code over and over. So in the framework/micro-architecture scheme, can I say that these are my internal in-house framework or are they part of a micro-architecture?

Trying to understand this topic better.
