The important premise of adopting service-oriented architecture (SOA) is the ability to increase enterprise agility through composition and reuse of coarsegrained services. However, without dynamic integration and alignment with business processes SOA would be nothing but yet another abstract architecture proposal. The response to that issue is Universal Description, Discovery and Integration (...

In this paper we describe a framework for exploiting the semantics of Web services through UDDI registries. As a part of this framework, we extend the DAML-S upper ontology to describe the functionality we find essential for ebusinesses. This functionality includes relating the services with electronic catalogs, describing the complementary services and finding services according to the propert...

Searching for appropriate web services on the internet is becoming more and more laborious, because it depends on human processing and evaluating of the available web services in UDDI repositories. Furthermore, if the requester language is different form available WSDL files then it would be more complicated. If this process could be done automatically, this will save effort and time. In order ...

An Extended Enterprise is comprised of not only the enterprise itself but also the enterprise's suppliers, clients and other associated organizations. The Extended Enterprise, in response to business needs and decisions, can dynamically alter these interrelationships, for example possibly swapping out some partners and swapping in others. Web services are an appropriate technology choice to fac...

As the World Wide Web has grown, it has been a challenge to allow meaningful understanding of content on the web. To face this challenge several technologies and initiatives have been introduced under the umbrella of web services among these are the SOAP and UDDI initiatives. This paper provides an overview of these initiatives. This paper will also discuss the challenges that may prohibit the ...

As international standards setting processes strengthen and converge, technologies fundamental to distributed systems architectures, such as XML, SOAP and WebServices, are being introduced into the marketplace. These facilitate the development of e-Commerce models and technology deployment patterns that allow both the closed, traditional e-hub and ‘open’ trading partner identification and appli...

The future of the web seems to be in machine-readable syntactic and semantic descriptions of machine-usable services, which enable also mobile devices to dynamically discover, select and invoke web services. This article presents methods proposed to add semantics to service descriptions with WSDL-S, and to enhance UDDI service directory with semantic references and external matcher services. So...

With WSDL, SOAP and UDDI, Web services are becoming popular with Web application. However, current Web services architecture is confronted with a few intractable problems. We shall give an overview of these problems and current efforts. Finally, we set an eye on the amalgamation of Web services and Grid technologies.
