What exactly do you mean by "virtual structure?" Just a ZZ
representation of the data in a specific file format-- or a set of
virtual cells describing the content of an actual external file, in such
a representation? Your wording seems to suggest the latter, but I'm not
positive I'm really understanding yet.

In any case, I agree that a ZigZag mapping of the data in common file
formats is a good thing. One I would like to propose as a starting point
is the Java .class format, because being able to represent it might make
writing a clang compiler easier; we want to write such a beast at some
point and hope that it will boost development. However, as it's not
quite time to do that, I won't insist on starting with .class. Word
would be another good starting point, because it's something interfacing
with is particularly important, but it's probably quite complex and twisted.

And, of course, XML... but bare-bones XML should be easy.

Just to emphasize: this is of course not what I was proposing; you can
standardize dimensions in any scheme for dimension identifiers, what I
was proposing was only to have a "super-scheme" for dimension
identifiers that works for all hypergrid implementations. But then of
course being able to define the dimensions once and for all impls makes
the value of standardized dimensions much greater.

The nice thing about standardized dimensions is that nobody is forced to
use them; if they don't do what you need, you can invent your own ones.

Where do you intend to start? Or do you have already?

Looking forward to discussion,
