IRS-III: A Broker for Semantic Web Services Based Applications

Abstract

In this paper we describe IRS-III which takes a semantic broker based approach to creating applications from Semantic Web Services by mediating between a service requester and one or more service providers. Business organisations can view Semantic Web Services as the basic mechanism for integrating data and processes across applications on the Web. This paper extends previous publications on IRS by providing an overall description of our framework from the point of view of application development. More specifically, we describe the IRS-III methodology for building applications using Semantic Web Services and illustrate our approach through a use case on e-government.

Semantics for Service-Oriented Architectures

“…Several tools are provided for WSMO, including a suite of reasoners for the different variants and an API for the programmatic management of WSMO elements and definitions. Moreover, there are implementations of execution environments for Semantic Web services, namely WSMX as the WSMO reference implementation (see www.wsmx.org), and IRS that provides a broker for Semantic Web services [14].…”

Multimedia Content Provisioning Using Service Oriented Architectures

“…As a result, we use our own RDF-based workflow model and language with added support for describing the streaming of data between participants. For the actual instantation there already exist systems, like IRS-III [9], which can create service compositions using goal based reasoning. However, creating and maintaining the domain ontology needed for the reasoning process is a complex and time-consuming task.…”

“…Common to these description languages is the modelling of actions in form of IOPE objects, specifying Inputs, Outputs, Preconditions and Effects. Instances of such languages are OWL-S, WS-CDL, BPEL, WSMO [12], or systems like IRS-III [9]. Respective languages from the multi-agent systems domain are given in [11] with a foundation in Action Logic, for instance systems like Golog [18].…”

Process Mediation of OWL-S Web Services

“…OWL-S broker [29] also assumes that the requester formulates its request as query which is used to find appropriate providers and to translate between the requester and providers. The work in [32] and [33] describe the IRS-III broker system based on the WSMO methodology. IRS-III requesters formulate their requests as goal instances and the broker mediates only with providers given their choreographies (explicit mediation services are used for mediation).…”
