Is there a difference between Compact and Sloping frames

[janiejones]

Is there a difference between what is often called compact (like Giant's OCR) and sloping top tube frames - for example, Ridley offer sloping frames such as the Boreas, Helium etc that are listed as "sloping top tube" but they also offer a frame called "Campact" which is named the same size for example a "small" but has different (smaller) measurements from the Boreas "small".

So is there such a thing as a "traditional" frame with a slightly sloping top tube.

The Treks seem traditional? Are they? looking at Allen Davis, you first think his frame is too big - but then you go hang on...

I'm getting a little confused about frame sizing these days.
