Abstract:
A growing number of domains are adopting semantic
models as a centralized gateway to multiple data sources, or
directly for modeling and managing relevant information.
In such contexts, granting access to the semantic model and
its data only to the authorized users is a crucial requirement.
In this paper, we present a fine-grained access control
model specifically tailored to regulate access to semantic
models. One of the relevant features of the model is the
granularity of the resources that can be protected. Access
control can be enforced at the level of both the model’s entities
and the entities’ instances. Authorization decisions are
determined by evaluating access control policies. An implementation
of the proposed model adopting the XACML
standard and the SeRQL query language is also discussed.
