Since the version of 3.7 it is possible to fetch attributes from the asset framework.
To do this derive from <code>OSIPI datapoint</code> and add a new integer property <code>OSIPI_SOURCE</code>, for which you select the <code>OSIPI_SOURCES</code> selective list (namespace: <code>System.Interface.Module.OSIPI</code>).<br/>
Choose <code>Attributes</code> as its value.<br/>
Since the version of 3.7.1 this property is provided as a system property via database update.
