Biblatex style=authoryear changes

Question

My bibliography is not perfect. I need to make some changes.

NOW:

MUSTERMANN, Hans (1994). The World Wide Web. URL: http:\\websiteisdown.tld\WoWiWe (besucht am 01.02.2013)

Better:

MUSTERMANN, Hans (1994): The World Wide Web. Online http:\\websiteisdown.tld\WoWiWe, Urldate is 02.2013.

The minimal example:

    \documentclass[a4paper,titlepage]{scrartcl}

\usepackage[utf8]{inputenc}

\usepackage[T1]{fontenc}

\usepackage[ngerman]{babel} % lang new german

\usepackage[babel,german=quotes]{csquotes}

\usepackage[style=authoryear]{biblatex}
\bibliography{literaturdatenbank}
\DefineBibliographyStrings{ngerman}{
    references = {Q}
}
% Names
\renewcommand*{\mkbibnamelast}[1]{\textsc{#1}}

\usepackage{filecontents}
\begin{filecontents*}{literaturdatenbank.bib}
@online{ art:web,
  author = {Hans Mustermann},
  title = {The World Wide Web},
  year = {1994},
  url = {http:\\websiteisdown.tld\WoWiWe},
  urldate = {2013-02-01}
}
\end{filecontents*}  

\usepackage[toctextentriesindented]{tocstyle}

\usepackage{hyperref}
\begin{document}






\section{Example}
Content
\footcite[Vgl.][]{art:web}.


\printbibliography
\end{document}

How can I fix this. Thank you.

Answer 1

I hope this is the result you're looking for.

To achieve it, add the following strings to ngerman:

\DefineBibliographyStrings{ngerman}{
    references = {Q},
    urlseen = {Urldate is},
    url = {Online}
}

Also, redefine the url and urldate as follows:

\DeclareFieldFormat{url}{\bibstring{url}\space\url{#1}\addcomma}
\DeclareFieldFormat{urldate}{\bibstring{urlseen}\space#1}

and add the line

\renewcommand*{\labelnamepunct}{\addcolon\space}

Complete MWE:

\documentclass[a4paper,titlepage]{scrartcl}

\usepackage[utf8]{inputenc}

\usepackage[T1]{fontenc}

\usepackage[ngerman]{babel} % lang new german

\usepackage[babel,german=quotes]{csquotes}

\usepackage[style=authoryear]{biblatex}
\bibliography{literaturdatenbank}
\DefineBibliographyStrings{ngerman}{
    references = {Q},
    urlseen = {Urldate is},
    url = {Online}
}
% Names
\renewcommand*{\mkbibnamelast}[1]{\textsc{#1}}
\renewcommand*{\labelnamepunct}{\addcolon\space}
\DeclareFieldFormat{url}{\bibstring{url}\space\url{#1}\addcomma}
\DeclareFieldFormat{urldate}{\bibstring{urlseen}\space#1}

\usepackage{filecontents}
\begin{filecontents*}{literaturdatenbank.bib}
@online{ art:web,
  author = {Hans Mustermann},
  title = {The World Wide Web},
  year = {1994},
  url = {http:\\websiteisdown.tld\WoWiWe},
  urldate = {2013-02-01}
}
\end{filecontents*}

\usepackage[toctextentriesindented]{tocstyle}

\usepackage{hyperref}

Some variants

With

\DeclareFieldFormat{url}{\textsc{\bibstring{url}}\space\url{#1}\addcomma}

you get

while with

\DeclareFieldFormat{url}{\mkbibacro{\bibstring{url}}\space\url{#1}\addcomma}

you get
