Translacja XTTML do innych formatów z użyciem XSLT. : ontologie (OWL), graphviz
proj z miw z zeszlego rokuReprezentajca 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;
}

Firefox tez sobier radzi z tralnslacja pliku (musi byc dostepny plik xtt2svg.xsl) : thermostat.xml

Celem projektu było stworzenie tlanslatroa XSLT z formatu XTT do plików dot oraz SVG. Niestety reprezentacja plików XTT nie prezentuje sie najlepiej w graphize. Ograniczenia jakie napotkałem podczas tworzenia plików dot są opisane poniżej:

Opis ograniczeń podejścia xttml→gv
Plik XSL: xttml → svg (XSL) xttml2svg.xsl
Działanie translatora zostało przetestowane na poniższych silnikach XSLT: Poniżej podano komendy wywołujące dany silnik.
XALAN
java org.apache.xalan.xslt.Process -in thermostat2.0.xml -xsl xttml2svg.xsl
