ODP, QoS, Enterprise Viewpoint, UML, Metamodelling
The QoS-ODP standardization initiative has led to a frame
work by which QoS aware ODP systems can be modeled
using ﬁve viewpoints. These viewpoints include an enter
prise viewpoint, which focuses on the objectives and poli
cies on the enterprise that the system is meant to support.
However, several issues have to be solved in order to in
crease the applicability of the QoS-ODP framework.
We address in this paper the need to develop formal
notations for the QoS-aware speciﬁcation of the ODP en
terprise viewpoint. The UML is being deﬁned as a formal
notation. Several approaches are being used in the ﬁeld of
the formalization of UML. For several reasons, we use the
metamodelling approach to deﬁne an UML meta-model of
the core QoS concepts and their relationships. This meta
model is the abstract syntax of a concrete language for
QoS-aware ODP enterprise speciﬁcations.
