Hi all, hello Damien!
DG> This thread is not very frequented now.
DG> May be because the debate has to become much more technical.
Yes, there is not so many traffic here nowadays. We knew this will be
a long project because it's a big project with many steps. There is
many questions to clarify, there is a huge amount of types of
connections/connectors, etc...
I promised we will keep the tips, the collected connections in tables
and update the proposal. We will do it ASAP, but now I have a little
bit technical problem but Jacob try to help me. (Many thanks to
Jacob!)

I think it's not a danger, it's the normal flow of development. At
first we defined the basic level (or layer) called LCD. This will
solve the connections and nothing more. The next layer is the LMPL
highly based on LCD. And maybe there will be additional layers too.
And all of these will work via GUI interface, so it means there is no
need to textual programming for the end user. (Similarly you not have
to code anything if you want to use LDraw. Only when you want develope
something new. Now you can develope only parts and nothing
more. If we want to define connections and later movements we will
need additional syntaxes and keywords to script them. Finally we can
call it a language. Also, I think the LDraw file format is a language.
Small, but language. :)
LAD> Let me report that LMPL is almost ready. It is going to be published soon.
DG> Good news. May be I will better know what I am talking about, when published.
LAD wrote it, and now I do the formatting and illustrating according
to the new LDraw.org site style. I try to do it ASAP, but it's more
complex and longer than the LCD. :)

And it must be flexible enough for future extensions. That's why we
think in layers.

Hm, this is a very interesting question!
In my humble opinion first we need to connect the parts somehow and
after that we can move the connected parts (as in real life) and start
to play with it. If we have no connections than we have nothing to
play with. (Imagine a minifig starting to walk. Without connections
the minifig will lose his/her head and all the other member. :)))
DG> I am currently at stage 1 (nothing is done).
DG> So my credibility is very low.
I trust you, so I encourage you to work out your approach as a
complete proposal!
