This work investigates the use of knowledge about organizational roles captured in enterprise models for service configuration. Based on an industrial case, it presents a way to extract a role's information demand and to use this as initial configuration for agent-based services. In addition to the metamodel included in the enterprise modeling language, the use of a common ontology is proposed which captures both, the perspective of information demand and services. The architecture of the agent-based services is following the idea to characterize all enterprise members and components by their functions and to represent them by sets of services provided by them. The main contributions of the paper are (1) to show that a role's information demand is relevant for service configuration, (2) to present a way of extracting information demand from enterprise models, and (3) to extend an approach for SOAbased enterprise representation with information demand.

Data Mashup is a special class of mashup application that combines information on the fly from multiple data sources to respond to transient business needs. Mashing up data requires an important programming skill on the side of mashups' creators, and involves handling many challenging privacy and security concerns raised by data providers. This situation prevents non-expert users from mashing up data at large. In this paper, we propose a declarative approach for mashing-up data. The approach allows data mashup creators to create data mashups without any programming involved, they just need to specify "declaratively" their data needs. The approach will then build the mashups automatically while taking into account the data's privacy and security concerns.

Abstract-The real value of Web services under the SOA paradigm lies in their ability to be assembled to obtain a new functionality. Assembling Web services can be achieved through a standard called BPEL, which creates executable processes by orchestrating Web service invocations. The problem with BPEL is the inability to separate the process description from its realization. In other words, it requires a prior retrieval of concrete Web services, which can be very challenging regarding the issues surrounding service discovery and selection.In this paper, we propose to separate a BPEL process description from its realization. We extend the notion of abstract BPEL processes, in order to enable developers to describe their desired orchestrations abstractly without identifying concrete services, according to three levels: the needed functionality, the expected QoS levels, and the composition flow. Then, the abstract BPEL process is realized by a selection framework that automatically discovers, classifies, and selects suitable services to render the process executable. Backup services are also discovered to assure the continuity of the realized process.
