-  abstract = {During the development of large software-intensive systems, developers use several modeling languages and tools to describe a system from different viewpoints. Model-driven and view-based technologies have made it easier to define domain-specific languages and transformations. Nevertheless, using several languages leads to fragmentation of information, to redundancies in the system description, and eventually to inconsistencies. Inconsistencies have negative impacts on the system’s quality and are costly to fix. Often, there is no support for consistency management across multiple languages. Using a single language is no practicable solution either, as it is overly complex to define, use, and evolve such a language. View-based development is a suitable approach to deal with complex systems, and is widely used in other engineering disciplines. Still, we need to cope with the problems of fragmentation and consistency. In this paper, we present the Vitruviusapproach for consistency in view-based modeling. We describe the approach by formalizing the notion of consistency, presenting languages for consistency preservation, and defining a model-driven development process. Furthermore, we show how existing models can be integrated. We have evaluated our approach at two case studies from component-based and embedded automotive software development, using our prototypical implementation based on the Eclipse Modeling Framework.}

-\section{Frames}
-\subsection{Title and Footer}

-    % Bei Frames mit Option \texttt{[t]} werden die Inhalte nicht vertikal zentriert, sondern an der Oberkante begonnen.
-	With frames with the option \texttt{[t]}, the content is not vertically centered but started at the top edge.
-\end{frame}
-
-\begin{frame}
-	With frames without a title, the free space for title can be used for content.
-\end{frame}
-
-\begin{frame}[plain]
-    % Bei Frames mit Option \texttt{[plain]} werden weder Kopf- noch Fußzeile angezeigt.
-	With frames with the option \texttt{[plain]}, neither header nor footer are displayed.
-	\\
-	The command \texttt{$\backslash$pagesNotes\{<label>\}} can be used to create a page with grid lines for notes, shown on the next slide. \\
-	\texttt{$\backslash$refnotes{<label>}} creates a symbol linked to the page with notes. \refnotes{note1}
-\end{frame}
-
-\subsection{Grid Page for Hand-written Notes}
-\pagesNotes{note1}
-
-\subsection{Footnotes}
-\begin{frame}{Footnotes}
-	\begin{itemize}
-		\item This is a normal footnote\footnote{This is a normal footnote.}.
-		\item \texttt{$\backslash$nomarkfootnote} creates a footnote without a mark in the text\nomarkfootnote{This is a footnote without a mark.}.
-		\item This is another normal footnote\footnote{This is another normal footnote.}.
-	\end{itemize}
-\end{frame}
-
-\section{Other Tips}
-\subsection{Citations}
-\begin{frame}{Citations using BibLaTeX}
-  Citations in beamer were often dealed by pasting the full text in the footnote. \\
-  The biblatex package enables citing from your .bib file. \\
-  Note that these commands requires setting \texttt{\schlagwort{backend=biber}} when loading the \texttt{biblatex} package.\\
-  Here are several ways of usage:\\[-.5em]
-  \begin{itemize}
-	\item Cite full text in footnote \footfullcite{Rode23ECOC} by \texttt{$\backslash$footfullcite}.
-	\item If the mark is not wanted, combine \texttt{$\backslash$nomarkfootnote} and \texttt{$\backslash$fullcite}. \nomarkfootnote{\fullcite{Rode23JLT}}
- 	\item Cite author and year in text \autocite{Rode23JLT}.
-  	\item Cite title in text \citetitle{Karanov18JLT}.
-\end{itemize}
-\textit{\footnotesize For more usage please refer to \href{http://tug.ctan.org/info/biblatex-cheatsheet/biblatex-cheatsheet.pdf}{\textcolor{kit-blue}{Biblatex Cheat Sheet}}.}\\
-%   \vspace{-1em}
-%   You can print all references that are cited at the end of presentation, as shown in the next slide.
-\end{frame}
-
-\subsection{Handout Mode}
-\begin{frame}{Handout Mode}
-	Handout mode is activated by the option \texttt{handout} in the document class.\\
-	A frame with multiple animated slides will be shown on one slide in the handout version.\\
-	One can still control the number of slides of one frame in the handout version, e.g.,
-	\begin{itemize}
-        \only<1|handout:0>{\item One: This will not be shown in the handout version.}
