JP 0.9定義の確認ページを公開

JP V0.9に基づいてOpen Peppolの電子インボイスの定義内容を表示するサイトを作成しました。

公式ページからダウンロード出来るスキーマトロンファイルには、BASICルールが含まれていません。そのため、python のライブラリを使って、ページの内容からデータを抽出してみました。ルールは、本家からページ内容をBeautiful Soupで読み出して加工していますので、誤っている箇所もあるかもしれません。

BASICルールは、未だ確認中のようで、次の様なものも含まれています。

UBLのCardinality定義が0..1なので、複数あるとスキーマ検証でエラーとなり、2つ以上定義出来ません。

次の定義は、BasicとSharedで同じ条件に対して違う表現を使用しており、あえてSharedのルールを定義しなくても良いと思います。

おまけ

Pytho3（Beautiful Soup）のプログラムは、下記です。
response = request.urlopen(base_url)
soup = BeautifulSoup(response,”lxml”)
response.close()
の３行でbase_urlで指定したページを読み込んでJSONファイルに保存しています。
