Named Elliptical Curve parameters Are named curve parameters always the same? I know this may be a stupid question however I think this is the case. For example the secp256r1 is defined in this documet http://www.secg.org/SEC2-Ver-1.0.pdf.
They are de facto conventions that somewhere may not being followed. I think the one you mention has started with the P1363, but not sure if there is something previous.

It is the first thing one have to check in any document: which is the naming convention followed there. Perhaps also is useful to see from there some of them comes. The Weierstrass Normal Form (or WNF) can be saw as:

$y^{2} + a_{1}xy + a_{3}y = x^{3} + a_{2}x^{2} + a_{4}x + a_{6}$

And usually uses it reduced form when is defined over $\mathbb{F}_{p}$ as:

$ y^{2} = x^{3} + ax + b $

On characteristic 2 ($\mathbb{F}_{2^m}$), I think is more usual the form:

$ y^{2} + xy = x^{3} + ax^{2} + b $

Different names for the same parameters and even mixing them. Not forgetting that there are many more curve representations, one each you can find even different conventions.

Then points naming can change from one document to another, where is usual to see $G$ as the generator (also represented as $&lt;G&gt;$), but cannot be assumed because you can see a $P$ or $Q$ or $R$. 

I think coherence is important and where ever it's used, the convention must be described at the beginning and followed to the end. This convention you mention, perhaps is the more spread.
