Taxonomy-Driven Adaptation of Multi-layer Applications Using Templates
Found in: Self-Adaptive and Self-Organizing Systems, IEEE International Conference on
By Razvan Popescu, Athanasios Staikopoulos, Peng Liu, Antonio Brogi, Siobhán Clarke
Issue Date:October 2010
pp. 213-222
Current adaptation approaches mainly work in isolation and cannot be easily integrated to tackle complex adaptation scenarios. The few existing cross-layer adaptation techniques are somewhat inflexible because the adaptation process is predefined and stati...
 
Template-Based Adaptation of Semantic Web Services with Model-Driven Engineering
Found in: IEEE Transactions on Services Computing
By Athanasios Staikopoulos, Owen Cliffe, Razvan Popescu, Julian Padget, Siobhán Clarke
Issue Date:April 2010
pp. 116-130
Service-oriented enterprise systems, which tend to be heterogeneous, loosely coupled, long-lived, and continuously running, have to cope with frequent changes to their requirements and the environment. In order to address such changes, applications need to...
 
Workflow Semantics of Peer and Service Behaviour
Found in: Theoretical Aspects of Software Engineering, Joint IEEE/IFIP Symposium on
By Antonio Brogi, Razvan Popescu
Issue Date:June 2008
pp. 143-150
In this paper we introduce SMoL, a simplified BPEL-like language for specifying peer and service behaviour in P2P systems. We define a transformational semantics of SMoL in terms of YAWL workflows, which enables the simulation (e.g., testing possible executio...
 
Design and implementation of Sator: A web service aggregator
Found in: ACM Transactions on Software Engineering and Methodology (TOSEM)
By Antonio Brogi, Matteo Tanca, Razvan Popescu
Issue Date:January 2010
pp. 1-21
Our long-term objective is to develop a general methodology for deploying (Web) service aggregation and adaptation middleware, capable of suitably overcoming syntactic and behavioral mismatches in view of application integration within and across organizat...
     
Semantics-based composition-oriented discovery of Web services
Found in: ACM Transactions on Internet Technology (TOIT)
By Antonio Brogi, Razvan Popescu, Sara Corfini
Issue Date:September 2008
pp. 1-39
Service discovery and service aggregation are two crucial issues in the emerging area of service-oriented computing (SOC). We propose a new technique for the discovery of (Web) services that accounts for the need of composing several services to satisfy a ...
