\end{itemize}
\textbf{Annotations and segmentation}\\
Metadata also consist in temporal information such as:
\begin{itemize}
-\item a list of \emph{time-coded markers} associated with annotations
-\item a list of of \emph{time-segments} associated with labels.
+\item a list of \alert{time-coded markers} associated with annotations
+\item a list of of \alert{time-segments} associated with labels.
\end{itemize}
The ontology for those labels is relevant for ethnomusicology (e.g. speech versus singing voice segment, chorus, ...).
It should be noted that annotations and segmentation can be done either by a human expert or by some automatic signal processing analysis.

\textbf{Audio features extraction}\\
Given the extracted features, every sound item in a given collection can be automatically analyze. The results of this analysis can be displayed as a support to ethnomusicological studies.
-Further works lead by the DIADEMS project will incorporate advance Music Information Retrieval methods in order to provide automatic annotation, segmentation and similarity analysis.
