Hi Jonathan,
BSWML is Binary SignWriting Markup Language. It is equivalent to BSW
but 3 times larger. The DTD is available online.
http://www.signpuddle.net/bswml.dtd
You can take a look at the other data equivalent forms on the BSW HTML
Reference.
http://signbank.org/bsw/#m
SPML will be a text file and it will include BSW as text using hex
values "0-9" and "a-f" with spaces to separate signs and punctuations.

Yes, the transition does take a bit of work. After the ISWA 2008, I was
hoping we wouldn't need to update the ISWA ever again. But a few things
were bothering me, and Val had a couple of issues. After some
discussion, we both agreed that now was the time for a focused refactor
before wide spread adoption.

I already have the conversion wired into SignPuddle. SignPuddle can
create BSW 2010 from the ISWA 2008 data. The conversion is 100%
accurate, unlike the IMWA conversion which was only 99.9% accurate and
much more complicated
SignPuddle will change over to the ISWA 2010 with SignPuddle 2 sometime
this summer before the next school year. The data for SignPuddle 2 will
be available very soon.

I created BSW before I had a way to parse it. I even considered using
YEX and YACC. But after much thought and research, I decided on tokens
with regular expressions. I can still remember the morning when I wrote
out the first regular expression to validate an entire sign text. The
heavens opened up, the angels were singing, and a beam of light flooded
my white board.
Regarding BSW, you can see the JavaScript library online. It has about
400 lines of code and it's relatively easy to understand.
http://www.signbank.org/swis/bsw.js
The tokensplit function is the real workhorse. If you can understand
how it's used, you can understand the library. There are 2 terms I
didn't define properly: segment and unit. A unit is either a sign or a
punctuation. A segment is a list of signs ending in a punctuation.
If you can reproduce the BSW library in your programming language,
you're ready to use BSW.
Thanks for being on the bleeding edge,
-Steve
