A principled approach to context schema evolution in a data management perspective

作者：

Highlights：

• The paper proposes a formal approach to manage the evolution of context schemas over time.

• Context schemas describe the possible contexts in a given scenario.

• The evolution strategy is founded on a sound and complete set of operators.

• The impact of the evolution on the context-aware data tailoring process is also studied.

• A prototype ensures the feasibility and efficiency of the approach.
