%\label{fig:metamodel}
%\end{minipage}
The Semantic Network of Information Management in Hospitals (SNIK) is an OWL 2 DL ontology with a modular architecture:
The meta model provides a common vocabulary for the domain of hospital information system (HIS) management.
% and thus defines, which superclasses and relations can be used., see \cref{fig:metamodel}.
It defines three basic disjunctive classes: Role (who), Function (does what) and Entity Type (which information is read and written).\\

\begin{posterbox}[name=methods,below=background]{Methods}
Semantic Web technologies principles are used to create, store and publish SNIK as Linked Open Data~\cite{sniktec}.
Subontologies are manually extracted from different sources and build upon the meta model by attaching their subclass hierarchies to the Function, Role and EntityType classes.\\

To achieve our aim of making SNIK available as Linked Open Data over several different interfaces, we publish SNIK under the CC BY-NC-SA 4.0 as:

\begin{subsectionbox}{SNIK Graph~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\url{http://www.snik.eu/graph}}
\emph{SNIK Graph} visualizes the structure of SNIK by modelling each class as a node and each RDF triple and OWL restriction as an edge:
\includegraphics[width=\textwidth]{img/snikgraph.png}
%SNIK Graph queries the list of classes and their relations from the SPARQL endpoint and transforms them into nodes and edges of the graph.
%Exploration options like the “spider worm”, which consists of the shortest path between a start node and an end node together with the end node’s neighbourhood, illustrate the context of a concept.
%The meta model and the subontologies can be freely accessed via SPARQL queries:

\end{subsectionbox}
\vspace{-0.5em}

\begin{subsectionbox}{SPARQL Endpoint~~~~~~~~~~~~~~~~\url{http://www.snik.eu/sparql}}
The SPARQL endpoint is the most expressive interface to SNIK but requires knowledge of both the SPARQL syntax and the SNIK meta model.
%Read access is publicly available at \url{http://www.snik.eu/sparql} 
It can be used both as an API and directly. Examples:\\

Which healthcare network components are not healthcare institutions?
\begin{lstlisting}
SELECT ?x {bb:HealthCareNetwork meta:entityTypeComponent ?x.
  MINUS {?x rdfs:subClassOf* bb:HealthCareInstitution.}}
\end{lstlisting}
How many functions is the CIO responsible for?
\begin{lstlisting}
SELECT COUNT(?f) {bb:ChiefInformationOfficer meta:isResponsibleForFunction ?f.}
\end{lstlisting}

\begin{posterbox}[name=discussion,column=1,below=results]{Discussion}
SNIK is published using open standards over interfaces with different compromises between expressivity and accessibility for different audiences.
Future work includes a dedicated ontology modelling tool.
%Different user groups can use the interfaces of SNIK that are most suitable to them:
%For example, the IT management of a hospital can use SNIK as a vocabulary to integrate data from different formats that result from application components from different vendors.
%Using the SPARQL query language, experts can also integrate applications with the SNIK ontology.
%Experts can also use the SPARQL query editor to answer specific questions.
%Students and teachers benefit more from SNIK Graph and the RDF browser, which intuitively presents knowledge without the need for technical skills.
