The symbols in the International SignWriting Alphabet 2010 (ISWA 2010) were designed by SignWriting inventor, Valerie Sutton (sutton@signwriting.org).
The symbols were transformed by Stephen E Slevinski Jr (slevin@signpuddle.net).
Available for review is a working prototype of a smart font technology that uses Graphite with a TrueType Font.
Smart font development by Eduardo Trapani: iswa.ttf, 6.1MB Github Source
The TrueType Font works with Graphite
Enable Graphite in the Firefox Browser: instructions
For comparison, view the reference example created using the SignWriting Icon Server

Derivative fonts are conceptually compatible, but are not supported directly in SignPuddle or the SignWriting Icon Server.
These two fonts were imagined and created by Jonatha Duncan. An original encoding, each symbol was analyzed for repeating shapes or peices. Each type of peices was only encoded once. Each symbol can be constructed with the common peices using XLink with Cartesian coordinates in SVG. His work is available on his SignWriting Studio download page.
Here are the numbers he is reporting.
| Font | SQLite | Text | SQLite Percentage of SVG Refinement | Text Percentage of SVG Refinement | ||||
