Translacja XTTML do innych formatów z użyciem XSLT. : ontologie (OWL), graphviz

• XSLT
• obsługa XSD
• repr. reguł w OWL, RIF?
• gotowe transl xslt do owl
• format graphviz: wizualizacja tablic

• próba translacji XTTML20 do graphviza

• syntetyczny opis ograniczeń podejścia xttml→gv (czego i dlaczego nie da się zrobić)
• próba zrobienia tego w SVG patrz proj z miw z zeszlego roku

Reprezentajca tabel w graphizie :

digraph structs {
 node [shape=record];
 struct1 [shape=record,label="<f0> left|<f1> mid\ dle|<f2> right"];
 struct2 [shape=record,label="<f0> one|<f1> two"];
 struct3 [shape=record,label="hello\nworld |{ b |{c|<here> d|e}| f}| g | h"];
 struct1 -> struct2;
 struct1 -> struct3;
}

Translacja XTTML20 do graphviza

• Translacja dotml do grapviza (dot) dotml2dot.xsl
• Translacja XTTML20 do dotml (XSLT) xtt2dotml.xsl
