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

Spotkania

080311

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

080318

  • próba translacji XTTML20 do graphviza

080401

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

Projekt

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;
}

Sprawozdanie

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:

xttml→gv

Translacja XTTML20 do graphviza

Opis ograniczeń podejścia xttml→gv

  • Tekst w komurakch tabeli nie moze zawierać znaków : <, >, }, {
  • graviz nie radzi sobie z odpowiednim ustawieniem przy złożonych diagramach (źle rysuje polączenia miedzy tabelami)

xttml→SVG

Plik XSL: xttml → svg (XSL) xttml2svg.xsl

Działanie translatora zostało przetestowane na poniższych silnikach XSLT: Poniżej podano komendy wywołujące dany silnik.
