+  <description>
+    <p>
+      DataLab is an open-source platform for scientific and technical data processing and visualization, with features designed to meet industrial requirements.
+    </p>
+    <ul>
+      <li>Process signals (1D): FFT, filtering, fitting, peak detection, stability analysis and more</li>
+      <li>Process images (2D): filtering, morphology, edge detection, blob detection and more</li>
+      <li>Apply processing in batches, with regions of interest</li>
+      <li>Record a history of actions and replay it on new data</li>
+      <li>Automate tasks with Python macros and extend the application with plugins</li>
+      <li>Control DataLab remotely from Jupyter, Spyder or any IDE through XML-RPC or an HTTP/JSON web API</li>
+      <li>Open data from many file formats (text/CSV, NumPy, MAT-Files, TIFF, PNG, DICOM, HDF5 and more) and save workspaces in HDF5 format</li>
+    </ul>
