Open Core model: how to manage the (moving) border

\begin{itemize}
\item
Avoid excessive proprietarisation
\item
Give enough space for companies to make a living
\end{itemize}
\end{block}
\pause
\begin{block}
{
Tracking impact
}
\begin{itemize}
\item
The proprietary paradigm has its own set of impact
indicators (patents, royalties
\ldots
)
\item
Full tracking is impossible with open source
\item
Work on indirect ways of ascertaining impact
\end{itemize}
\end{block}

{
Challenges 2/2
}
\begin{block}
{
Monetisation
}
\begin{itemize}
\item
Challenge self-financing model for KT or
\ldots
\item
Try to find some sources of revenue compatible with open
source (see examples in software like the Linux Foundation)
