This is quite a bit different than what I took from the book (and I no
longer have it with me). What you now seem to be claiming is that a
meta-representation is a process rather than a thing. It the process of
comparing different representations in different representation systems and
modifying them based on those comparisons.
So then memetic reproduction would be the transfer of those processes?
What I took from your book was that a meta-representation was a higher
level representation that could be applied broadly to a number of a
objects. So for example, "blue" would be a meta-representation because it
was a property that applied to a number of different objects. Alex has not
only the ability to recognize "blue" and identify it, he can also recognize
the concept of "color", which I thought would have been a
meta-representation of a meta-representation.

Alex would of course have a had a bit of trouble recognizing French, but
then so would I. He does though engage in self-reflection. When left
alone, he babbles to himself, combining the words he has in to different
combinations.
I still think that you are underestimating the reasoning capacity of
animals. Let me give you another example: a rhesus monkey was observed
trying to climb a tree with very thorny bark. The monkey found some leaves
and wrapped them around its feet, and then made its climb. Clearly, the
monkey was doing some pretty complicated thinking there.

Doesn't discernment through these advanced forms of imitation require
outside information? If it is going to be something other than rote
copying, doesn't there have to be another representation to compare to and
draw infererences from? And doesn't this run into exactly the same problem
you allege for copying of artifacts?

I disagree. Now, I only took piano lessons for a few months, but I
remember that I had to be careful about which finger to use to play a
certain note, so that I could reach the next set of notes with the right
set of fingers. The score doesn't tell me which fingers to use. Yes, an
experienced pianist knows this, but it certainly isn't contained in the score.
In fact, I would argue that there is actually more information contained in
the recording than in the score. A piece played exactly according to a
score can still sound wooden, while a piece played by an expert will have
enhancements about it that a discerning listener will be able to pick up on
and apply that they could never find in the score.
Here's another example:
This is the enabling language from a patent (actually one my brother was
the inventor of). It is the entire body of words that defines the legal
boundaries of the invention itself:
"What is claimed is:
1. A method of forming an interconnection comprising:
depositing a masking material over a first conductive region of an
integrated circuit substrate;
depositing a dielectric material over the masking material;
forming a via through the dielectric material to expose the masking material;
depositing a first photoimageable material in a portion of the via over the
exposed masking material such that the via is partially filled with the
first photoimageable material; after depositing said first photoimageable
material depositing a second photoimageable material and patterning said
second photoimageable material over the dielectric material defining an
area for a trench
after patterning the second photoimageable material, forming a trench in
the dielectric material over a portion of the via;
removing the first photoimageable material from the via;
extending the via through the masking material; and
depositing a conductive material in the via."
Could you make this invention now, or would you require some outside
information?\

You've left me with more questions. Which I suppose might go further to
demonstrate that the representation system itself does not always contain
all the information necessary to convey the underlying ideas. Or perhaps I
actually understood the ideas, and there were a few actual flaws there.
