Abstract:

This paper overviews and compares the DERI and DEI-Cefriel approaches to the SWS-Challenge workshop

mediation scenario in terms of the utilized underlying technologies and delivered solutions. In the mediation

scenario one partner uses RosettaNet to deﬁne its B2B protocol while the other one operates on a proprietary

solution. Goal of the workshop participants was to show how could these partners be semantically integrated.

1 INTRODUCTION

This paper compares two different approaches to

semantic integration of a RosettaNet-enabled client

with legacy systems in the context of the Semantic

Web Services Challenge (SWS-Challange)

work-

shop series. Here we compare the submissions of

the Digital Enterprise Research Institute

and the joint

team DEI

and Cefriel

to the mediation problem.

The solutions of both groups differ quite sub-

stantially in terms of the underlying technologies.

The DERI team based its solution on WSMO con-

ceptual framework for Semantic Web services which

comes from the quite young Semantic Web research

area while DEI-Cefriel followed the path of well-

established Software Engineering methods. We com-

pare the similarities and differences of provided so-

lutions mainly with respect to the data and process

modeling, execution environments, tool support and

changes required in the solutions once the integration

requirements change.

The paper is structured as follows. First we

overview our approaches, in section 2 the DERI team

submission is described while in section 3 that of

DEI-Cefriel is described. Section 4 provides in-depth

comparison of our submissions. In section 5, we pro-

vide reference points to other works in the area of se-

mantic integration. Finally, in section 6 we describe

our further plans and conclude this paper.

2 SOLVING THE SERVICE

MEDIATION SCENARIO WITH

WSMX

In order to address the SWS-Challenge requirements,

DERI based its solution on the speciﬁcations of

WSMO (Roman et al., 2005), WSML (Roman et al.,

2005) and WSMX (Mocan et al., 2006b) providing a

conceptual framework, ontology language and archi-

tecture for Semantic Web services.

2.1 Environment

The following artefacts have to be created during the

design time phase to apply WSMX middleware to

the system integration: ontologies for both involved

parties (i.e. service requestors and providers), bidi-

rectional XML–WSML adapters and lifting/lowering

rules, WSMO Goals and Services, data mediation
