Special style for commentary citations

Question

I need to have a special citation style for commentaries in my thesis. I hope he following example illustrates the problem sufficiently:

\documentclass[fontsize=10pt, fleqn, pdftex, version=last, x11names,pointlessnmbers]{scrartcl}
\usepackage[]{ngerman, geometry, graphicx, keyval, ifpdf, ifvtex, placeins, nicefrac, abstract}

\section{Section to illustrate the problem}
Here ist how the commentary should be quoted in the bibliography:\\[0.5cm]
\textsc{Mustermann, Max} (Hrsg.), Zürcher Kommentar, 5. Aufl., Zürich 2013 (zit. ZK - \textsc{Bearbeiter}, Art. N Rn. N)\\[1cm]
And thats how the citation has to look like:\\[0.5cm]
ZK - \textsc{Bearbeiter}, Art. 500 Rn. 3.\\[1cm]
And this is how it looks like right now\footnote{vgl. \cite[Bearbeiter][Art. 500. Rn. 3.]{ZK}}.

\end{document}     

@commented{ZK,    
    Date-Added = {2013-10-12 15:40:02 +0200},
    Date-Modified = {2013-10-12 15:42:11 +0200},
    Editor = {Max Mustermann},
    Howcited = {ZK},
    Publisher = {Z{\"u}rich},
    Shorttitle = {ZK},
    Title = {Z{\"u}rcher Kommentar},
    Year = {2013}}

Answer 1

jurbib implements an author (title if necessary to disambiguate more works by the same author(s)) citation style, while you seem to favour a title style, so jurabib might not be the best choice after all.

The separator between the comment and the commenting author is easily changed by \DeclareRobustCommand{\jbhowsepannotatorlast}{ -- }%.

To get the shorthand for the commentary instead of the author/editor, the easiest way seems to be to put the commentary title into the shortauthor field, like so:

@commented{ZK,    
  Editor = {Max Mustermann},
  Publisher = {Z{\"u}rich},
  Shorttitle = {ZK},
  Shortauthor = {ZK}, % this is new (and quite an abuse of the shortauthor field)
  Title = {Z{\"u}rcher Kommentar},
  Year = {2013}}

Normally, jurabib uses the author/editor to cite a work, not the title, so we abuse the shortauthor field.

There seems to be no sensible way to get the "Art. 500 Rn. 3" stuff in the bibliography, however, but it does not seems to make too much sense: one would not say "cited as Knuth 1986, p. 5" in the bibliography.

To get a comma between the citation and the page use the package option commabeforerest=true,.

The MWE

\documentclass[ngerman]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{filecontents}
\usepackage[utf8]{inputenc}
\usepackage[
  howcited=multiple,
  authorformat=smallcaps,  
  commabeforerest=true,
]{jurabib}

\begin{filecontents*}{\jobname.bib}
@commented{ZK,    
  Editor = {Max Mustermann},
  Publisher = {Z{\"u}rich},
  Shorttitle = {ZK},
  Shortauthor = {ZK},
  Title = {Z{\"u}rcher Kommentar},
  Year = {2013}}
\end{filecontents*}

What you want seems to be easily - and more semantically correctly - implementable in biblatex (with biblatex-juradiss, you can find the biblatex-juradiss documentation here), see biblatex and German juristic commentaries.
