Hi SignWriting list,

     I want to congratulate Profo Rubens Almeida and team for the 
beautiful work they put into this project.

Val and Steve,

     I was thinking that it's great you are working so that they can add 
they other symbols to the ISWA 2020.  But I am also thinking that there 
is what I feel is a shortcoming to the ISWA 2010, which is easy 
extensibility to create new handshapes.  I believe if the members of 
SignWriting community who had an issue the the thumbs, if they had 
easier ways of creating new handshapes and sharing them it wouldn't of 
been more enjoyable for them. Also for my hand shape selections, no all 
symbols look quite the way they should in each position as is.  It 
would've been nice to have alternative handshapes that fit more with 
what they would like to choose, where they expect it or show them only 
the ones in ISWA 2010 like they have now.

I'm not sure which ones were most problematic just right now.

I think the idea of composing new symbols from the pieces is nice.  It 
would also be backwards compatible with ISWA2010 without any problems.  
The real issues are really

1- keep the parts of the new symbols together so that they can all be 
moved together.

2- displaying them in the symbol area to choose to include in a sign.

In my opinion, a way to do these two things would be more beneficial 
than add a few new symbols every 10 years.

To do it we would need a way to group symbols together within a sign so 
that they can be moved all together. Maybe creating an extension to FSW 
to tell the program which symbols should be treated as one symbol.

A separate piece of data to let the programs know under which finger 
group to display them,  and just display them at the end of the existing 

Have a way to distinguish the created symbols, possibly by a hash of the 
codes of the symbols making it up plus its rotation and palm facing.

I think it would be a better long term solution than changing symbols 
out from ISWA2010 to ISWA2020.

If you decide to replace some of the symbols in the new ISWA2020 and 
create FSW.  How will people know not to load it in programs that still 
have ISWA2010?   They signs would become unreadable in those programs as 
they would have the old symbols.  Of course this will only be a problem 
for people having written something with the new symbols in Brazil.

I was just wondering if you had thought of a solution for this problem.

The only solution that I can think of is to version the FWS and other 
outputs to let the programs know which set of symbols it is 
representing, if you use the same values.

If we only create composite symbols, then they can work in all 
programs,  just that the older programs we will have to drag all the 
pieces of a symbol one by one. Or in my programs, try to select them 
together to drag them together.

I realize that ISWA2020 replacing some of the symbols from ISWA2010 is 
the fastest way to do it but without backwards compatibility.

Look forward to your responses.
