The proliferation of Data as a Service (DaaS) available
on the Internet and offered by cloud service providers
indicates an increasing trend in providing data under Web
services in e-science and business domains. While data usage and
selection are dependent on different constraints established on the
basis of several data concerns, for example, quality of data and
data privacy, existing data service engineering approaches lack
techniques to allow the evaluation, association and publishing of
such concerns with data provided via DaaS. Furthermore, data
sources behind DaaSs are not static but dynamically changing,
thus requiring the evaluation and publishing of data concerns to
be dynamic and on-the-fly as well. In this paper, we present
a novel data concern-aware service engineering process for
evaluating and publishing data concerns inside DaaS that covers
different evaluation and publishing scopes, modes, and integration
models. Based on our process, we present a framework and
its implementation for the evaluation and publishing of quality
of data metrics associated with data provided by DaaSs. In this
paper, we also perform several experiments to demonstrate the
usefulness of our framework.
