Nice Igor!
Do you plan maybe on writing a book about pawn structures in the openings? 
Principal opening strata and transitions

Many transitions are obvious just from their stratification codes. For example,
3g|5d + 4c|6e --> 4c3g|5d6e
indicates how someone can transit from King's Indian attack (A07) to English: Agincourt (A13).

LoL Actually, not so much hard work, everything is almost obvious!
Yes, but such categorizing doesn't show the transition from one opening to another.

Ajedrecito, nice!
U can write 3c4de|5cd6e instead of 3c4d4e|5c5d6e. And yes, the push of white e-pawn is +1e|.

If you put that skeleton on the board you will see that at first it is a Sicilian, then a French.
An interesting study for students of the game would be to analyze openings with very similar or identical pawn structures, but different piece placement (bad bishop inside vs outside chain, etc) to see what the advantages and disadvantages are of certain move-orders and what plans are relevant in positions reached from certain move-orders with the same basic structure.
Yes, indeed, U have nicely explained the basis of my presentation.
Nice!
It would be great to show the difference between whitesquared bishop and a blacksquared one in this pawn structure. Caco-Kann ( 1. e4 c6 2. d4 d5 3. e5 Lf5 ) has similar pawn structure without the weakness of a whitesquared bishop and there the difference can easily be spotted by begginers.
Yes, I know that... but I think it's better not to have a weak bishop, than to lose more moves than one to exchange it ( Bd7, Qb6, Bb5 or similar in French ). I don't play any of them as black... but I avoid playing Advanced Caro-Kann, while Advanced French is my main weapon, for white. It's just my opinion.

How would you classify this Sicilian to French transition?
Very nice example for a transposition bolevole - I was not aware of that !
There is another example, that I like:
Do you know more of them ?

Cool !
Transpositions are amazing tools. Luring opponents into your own system !
Well, it's natural to stratify all chess positions by pawn structures. I started to look at Game Explorer (up to A50 now) and to make a list of principal strata. I'm also planning to describe all transitions between them.
