genealogytree：如何在通用密钥中保存数据库密钥

Question

通常在家谱树节点我必须说
p[]{name=Jane, birth={2-2-1888}{somewhere}}

我怎样才能创建一个键，像persdata=JaneID扩展为的一样name=Jane, birth={2-2-1888}{somewhere}，这样我只需要说：
p[]{persdata=JaneID}

不工作或不正确的 MWE：

\documentclass[landscape,paper=a5]{scrartcl}
\usepackage[all]{genealogytree}

\begin{document}
% Works not: 
\pgfkeys{
     persdata/.initial={name=Jane, birth={1-1-1777}{somewhere}},
     persdata/.get=\persdata,
     persdata/.store in=\persdata,
}
\gtrset{database/save/persdata/.get=\persdata}


\begin{tikzpicture}[]
\genealogytree[template=signpost, 
processing=database,
]{
parent{
g{name=first child}
c{name=second child}
c{name=third child}
p[]{persdata=JaneID} % <---------------- Problem here....
p[]{name=works, birth={1-1-1777}{somewhere}}
         }
}
\end{tikzpicture}
\end{document}

Answer 1

此答案提供了一个新的/gtr/database键persdata，它接受预定义的选择，例如JaneID。persdata=JaneID使用时，将检索以该样式存储的相应键值列表。

\documentclass[landscape,paper=a5]{scrartcl}
\usepackage[all]{genealogytree}

\begin{document}

\gtrset{
  database/.cd,
  persdata/.is choice,
  persdata/JaneID/.style={name=Jane, birth={1-1-1777}{somewhere}}
}


\begin{tikzpicture}[]
  \genealogytree[
    template=signpost, 
    processing=database,
  ]
  {
    parent{
      g{name=first child}
      c{name=second child}
      c{name=third child}
      p[]{persdata=JaneID}
      p[]{name=works, birth={1-1-1777}{somewhere}}
    }
  }
\end{tikzpicture}
\end{document}
