  We present VOnDA, a framework to implement the dialogue management
functionality in dialogue systems. Although domain-independent, VOnDA is
tailored towards dialogue systems with a focus on social communication, which
implies the need of long-term memory and high user adaptivity. For these
systems, which are used in health environments or elderly care, margin of error
is very low and control over the dialogue process is of topmost importance. The
same holds for commercial applications, where customer trust is at risk.
VOnDA's specification and memory layer relies upon (extended) RDF/OWL, which
provides a universal and uniform representation, and facilitates
interoperability with external data sources, e.g., from physical sensors.
