Welcome to the Sortal.org website.
Sortal structures are representational structures based on a concept for representational flexibility. Sortal grammars are a formalism (or rather, a class of formalisms) for design grammars, utilizing sortal structures as representational structures.
If you're interested in exploring sortal grammars, you may download SortalGI, a sortal grammar interpreter developed for the Processing programming environment.
Please be aware that this website is still under development, and as such missing some information. We hope to correct this as soon as possible.
